Closer to user needs Canon EOS 650D in-depth evaluation

IT 168 evaluation 2012 in June, canon released a new generation of high-end entry-level SLR camera EOS 650D. Canon, which adheres to the balanced route, did not upgrade the pixels this time, but further improved the performance of the camera. EOS first joined the touch screen, APS-C size sensor first joined the phase difference detection? Can these help EOS 650D become the king of entry for the first time? Please see the in-depth evaluation brought by IT 168.

Canon EOS 650D didn't upgrade pixels this time, but the picture quality should be improved because of the addition of DIGIC 5 processor. Speaking of the most attractive upgrade, EOS 650D adds a multi-touch touch screen and a newly upgraded focusing system.

â–² Overview of Canon EOS 650D

Although Canon regards these upgrades as very important progress, many people are complaining that Canon has not upgraded the pixels of EOS 650D. In fact, from the release of EOS 5D MARK III this year, we can see that Canon is taking a balanced route? The balance between pixel and image quality. So pay more attention to whether the high photosensitivity of EOS 650D has been improved, whether the touch screen can bring us different control, and whether the latest focusing system can bring high-speed real-time focusing. These are the real highlights of EOS 650D d.

The appearance of 650D has no obvious change.

EOS 650D and EOS 600D are almost identical in appearance. The appearance, feel and button layout are the same, so users who are familiar with Canon EOS 600D will easily get started with EOS 650D, but how many EOS 600D users will upgrade 650D?

â–² Front view of Canon EOS 650D

The volume of Canon EOS 650D is about133.1x99.8x78.8mm and its weight is 575g. It is a plastic body. Although EOS 650D is small and light, its overall workmanship is not sloppy. There are decorative skins on both sides of the fuselage, which can be said to be the advanced goods in the entry-level SLR.

â–² Canon 650D rear view

The layout of buttons on the back of Canon EOS 650D fuselage is the same as EOS 600D. Perhaps because the layout of EOS 650D is very reasonable, EOS 650d has not been changed. Of course, the biggest attraction of EOS 650D is also behind the fuselage? Brand-new 3-inch 1.04 megapixel touch screen.

This touch screen is a capacitive screen, which supports up to 4 points of touch, and 1.04 million pixels can also get a very good playback effect. But whether it can bring us a good operating experience or not will be explained in detail below.

â–² Top view of Canon EOS 650D

Compared with EOS 600D, Canon EOS 650D mode turntable has an important function, that is, hand-held night scene function. The author believes that as an entry-level product, more such functions are closer to users. As for the hand-held night view, we will explain it in detail below.

In addition to the hand-held night scene function, starting from EOS 650D, the most obvious is the two microphones next to the hot boots. It seems that Canon is determined to make its SLR products have professional video shooting function.

â–² Canon EOS 650D Left (photographer's direction)

Canon EOS 650D has a flash button and a depth of field preview button on the left. At the same time, the MIC interface, HDMI interface, video output interface and cable release interface are all on the left.

â–² Canon EOS 650D interface

MIC interface can record purer sound when shooting video and avoid noise interference. EOS 650D has its own video output line, which can directly play back photos on TV. If you don't have to watch HD playback, you don't need an HDMI cable.

â–² Right side of Canon EOS 650D (photographer position)

Because the operation of the right hand on the camera mainly lies in the top and back of the camera, there are no buttons on the right side of the Canon EOS 650D fuselage. The card bin is located on the right side of the camera body, and the card bin is designed with a single SD card, which is the standard configuration of entry-level SLR cameras at present.

â–² Canon EOS 650D card warehouse.

Because the Canon EOS 650D has 6.5438+0.8 million pixels, a single photo file is not small (about 9M). I suggest that everyone should be equipped with at least an 8G SD card. Full HD camera shooting, everyone should be equipped with at least one SD card with a speed of more than 8 categories.

â–² Canon EOS 650D bottom view

Canon EOS 650D has a metal tripod hole at the bottom, and the product model and code are also at the bottom of the camera. Check the three codes in one when purchasing. You need to see here. (Three codes in one: the package code, warranty certificate code and body code must be consistent before the warranty can be guaranteed. In addition, the battery compartment of Canon EOS 650D is also at the bottom of the fuselage.

â–² Canon EOS 650D battery compartment

â–² Canon EOS 650D uses a battery.

Canon EOS 650D adopts 1 120mA LP-E8 lithium-ion rechargeable battery, which is similar to the previous generation EOS 600D. It is no problem for the author to take 600 pictures after actual use. For Canon EOS 650D, if you don't travel frequently, there is no need to prepare another battery.

Appearance summary:

From the overall material, shape and key layout of EOS 650D, it shows that EOS 650d is an entry-level product, and there is no need to criticize its plastic shell as plastic slippers. At the same time, continuing the shell layout of Canon's three-digit series will help old users get started quickly, and the flip screen of EOS 600D will help users take photos and take selfies. In short, for an entry-level SLR, EOS 650D has nothing to be picky about in appearance.

Canon EOS 650D has a good resolution.

Although the Canon EOS 650D has not changed in pixels, the resolution performance of the original EOS 600D is still good. And for cameras equipped with APS-C size sensors,18 million pixels is enough.

In the test, we used Canon EOS 650D equipped with EF 50mm F 1.4 USM lens to shoot the sample of ISO 12233 resolution target (line 4000), and tested it by Imatest software, and finally got the best resolution value. The following are the best resolution test results of Canon EOS 650D:

â–² Canon EOS 650D best resolution test results.

The test results show that the optimal resolution of Canon EOS 650D JPG has exceeded 3,000 lines, while the resolution of Raw to JPG has even reached about 3,500 lines, nearly 500 lines higher than JPG. This achievement has been very good in the current APS-C format SLR.

â–² Canon EOS 650D JPG directly gives the best resolution visual effect.

From the actual visual resolution, the best resolution of JPG is only about 2,800 lines horizontally and 2,600 lines vertically, which is lower than the test result of Imatest, but the visual effect is more in line with the actual level of18 megapixel SLR.

â–² The visual effect of Canon EOS 650D RAW to JPG with the best resolution.

For the visual effect of RAW to JPG resolution, the horizontal resolution and vertical resolution have reached about 3200 lines. Canon EOS 650D will have better sharpness when using RAW to JPG, which is also the performance of SLR cameras.

Canon EOS 650D is excellent in definition measurement.

Resolution test can let us know the theoretical definition of a camera, but it is best to see if the photo can reach the definition we want.

â–² Clarity test environment

We used Canon EOS 650D to take this photo in a standard evaluation environment. The lens used was EF 50mm F 1.4 USM, the shooting parameter was F8 aperture under A file, and the sensitivity was set to ISO 100. For the convenience of comparison, we 100% cut off four parts (the red box area above) of the sample taken by Canon EOS 650D for observation.

â–² Canon EOS 650D definition proofs 100% screenshot.

From the real shot of definition, the overall picture details of Canon EOS 650D are good, which can be seen from the front of the banknote, but there is a slight pseudo color in the background. The actual definition of EOS 650D is consistent with the resolution test results, and its performance is quite sharp, not losing to the previous generation EOS 600D, which is the best definition in Canon APS-C format SLR.

Solution summary:

On the whole, Canon EOS 650D seems to have inherited the high sharpness of EOS 600D and made some progress. For the average user, 6.5438+0.8 million pixels and such sharpness performance are enough to meet any demand. There is absolutely no need to be upset because the number of pixels has not reached 24 million.

EOS 650D has excellent sensitivity.

Canon EOS 650D upgraded the image processor compared with 600D, because it still has18 million pixels. Number 5. So we must look forward to the high-sensitivity performance of EOS 650D in detail.

The following scenario is the standard sensitivity test environment of IT 168 evaluation room. We fixed the camera on the gear platform of a heavy tripod and let the camera shoot the photosensitive effect of each gear motionless. Then we cut the photo slice from the same position in the above picture, as shown in the red box, to see how the sensitivity of EOS 650D is.

â–² Sensitivity test target and slice range

First, let's shoot a set of JPG slices with noise reduction turned off.

â–²EOS 650D JPG directly displays the ISO performance of each file.

From the sample, we can see that Canon EOS 650D has fine imaging and good image quality at ISO 800 and below. In ISO 1600, the graininess is slightly obvious, but it is completely available. 𙌠graininess sensitivity is aggravated, and the color deviation is obvious. The author believes that the highest sensitivity required for excellent image quality is between ISO 1600 and ISO 3200.

Let's look at the comparison between a group of original JPG and JPG. See if RAW format shooting will get better high-sensitivity effect. But for a camera like EOS 650D, if the quality of high-sensitivity photos taken by RAW is obviously better than JPG, it will be a tragedy for the majority of primary users.

Judging from the test results, the photos taken by Canon EOS 650D using RAW will have better definition. However, the available sensitivity still does not exceed ISO 3200. Although the use of RAW is beneficial to the later stage, for EOS 650D, JPG can be used to avoid the burden brought by the later conversion format.

Summary of high sensitivity test:

On the whole, the high sensitivity performance of Canon EOS 650D is in a good position in the current mainstream entry-level SLR. Although the available sensitivity has not been improved to ISO 3200, the availability of ISO 1600 is already a great achievement in APS-C format SLR. The gap between the high sensitivity performance of Canon 650D and Nikon D4 is less than 1.

Where is the high sensitivity level of EOS 650D?

The entry-level SLR has always been a battleground for military strategists. EOS 600D once had a very good performance in the entry-level market. Today we compare the high performance of EOS 600D, Nikon D3200 and EOS 650D.

Canon EOS 650D adopts the latest DIGIC5 image processor, which should have better high-sensitivity performance than EOS 600D. But from the actual comparison, EOS 650D is only sharper than EOS 600. Compared with EOS 600D, the high sensitivity of EOS 650D is improved by almost 0.3EV.

Although Canon EOS 650D is not as good as Nikon D3200 in pixels, it has obvious advantages in high-sensitivity performance. The performance of EOS 650D in ISO 3200 is between Nikon ISO 800 and ISO 1600, and its high sensitivity performance is better than D32001.7ev..

It can be seen that the Canon EOS 650D has advantages in high-sensitivity performance, whether compared with the previous EOS 600D or compared with the competitor Nikon D3200. If you want to buy an entry-level SLR with good image quality, Canon EOS 650D is the best choice.

"EOS 650D noise reduction can be set to normally open.

Professional photographers generally choose RAW+ noiseless shooting. This can get a good sharpness. As for high ISO, the more the better. But for ordinary users, turning on noise reduction is the best way to get good image quality. So the author tested three kinds of noise reduction effects of EOS 650D? Low noise reduction, high noise reduction standard.

In ISO 800, after turning on different noise reduction effects, we can see that with the increase of noise reduction, the noise of the picture is also decreasing, and the clarity of the picture is also decreasing. From the actual effect, the effect of standard noise reduction has both fine image quality and sharpness retention.

In ISO 1600, the effect of turning on different noise reduction is similar to that in ISO 800. The standard noise reduction is the balance of picture clarity and fineness. The picture with noise reduction turned off has some color cast, but the color cast is not obvious after noise reduction turned on.

In ISO 3200, the picture without noise reduction has obvious graininess and color cast, and the gear with low noise reduction cannot effectively suppress graininess and color cast. The loss of sharpness is also very obvious in standard noise reduction and high noise reduction.

In ISO 6400, the graininess of the picture is very serious. Because of this severe graininess, standard noise reduction and high noise reduction have better sharpness retention than no noise reduction. Through the comparison of noise reduction effects, it is recommended that you use for the degree of noise reduction. Noise reduction standard? This gear.

Noise reduction test conclusion:

For the majority of primary users, we can set the amount of noise reduction at the noise reduction standard. In this gear, the high-sensitivity photos taken not only have a certain sharpness, but also have a much more delicate picture.

"EOS 650D has a hand-held night view function.

In addition to improving the sensitivity, EOS 650D also provides an option: hand-held night scene function. This function, which has long been popular in Sony's all-in-one system, is actually very useful for beginners, and the author often uses this function in many external shots.

With the hand-held night scene function of Canon EOS 650D, the shutter speed of the camera will be automatically set to the reciprocal of the equivalent focal length (65438+ 0.6 times of the actual focal length), so as to ensure the safety of the shutter and prevent hand shaking.

Under ISO 1600, through the superposition of four photos, the photos obtained by hand-held night scene function are better than those directly taken by ISO 1600 in aperture priority mode. For ordinary users, shooting night scenes is not only simple, but also better results can be obtained by directly adjusting the mode dial to the handheld night scene mode.

In a dark environment, the graininess of the photos taken by the hand-held night vision function of Canon EOS 650D is obviously smaller than that of ordinary mode photos exposed at the same sensitivity. However, after using the hand-held night scene function, the clarity drops obviously. I wonder if it has anything to do with the author's shaking hands. If this is the case, I believe most photographers will be distressed by the decline in sharpness, because the author's iron fist is not bad.

In addition, due to the superposition of four photos, the imaging range is smaller than the framing range. When there are four photos in continuous shooting, the imaging range changes according to the camera moving range.

Summary of noise reduction evaluation:

The author thinks that the hand-held night scene function of Canon EOS 650D is very easy to use. Do you need a tripod to shoot at night? For beginners, no, because there is a hand-held night scene (this sentence has been said many times when using Sony micro-single).

Canon EOS 650D automatic white balance works well.

Clarity and high-sensitivity imaging are important manifestations of image quality, and the color performance of Canon EOS 650D is also worthy of attention. One is to see whether the white balance of EOS 650D can accurately restore the original color temperature of the object, and the other is to see what kind of theme the overall color tendency of Canon EOS 650D is more suitable for.

â–² Color test environment

In order to understand the imaging style of Canon EOS 650D, in the color test, we equipped EOS 650D with EF 50mm F 1.4 USM lens, set automatic white balance and manual white balance to shoot standard color cards respectively (the red box area in the above picture is the color test range), and obtained the final data through imatest software:

â–² Canon EOS 650D Manual White Balance Test Results

This test chart reflects the difference between the actual imaging color value and the ideal value of Canon EOS 650D. The part surrounded by gray lines in the picture is the color gamut range of Canon EOS 650D. The square color block in the test chart is the ideal color value, and the circular color block is the actual shooting value.

Among them, manual white balance exceeds the sRGB color gamut by 20.4%, and Canon EOS 650D has moderate bright color, which can be used for post-processing and direct output. At the same time, EOS 650D is sensitive to red and suitable for portrait shooting, which is also Canon's consistent imaging style.

â–² Canon EOS 650D automatic white balance test results.

In terms of automatic white balance, Canon EOS 650D's automatic white balance color temperature is very accurate. As the Canon EOS 650D, which mainly faces the primary user market, automatic white balance will be everyone's main purpose. Automatic white balance can accurately display the original color temperature of the picture, which is very important for users.

Color evaluation summary:

Canon EOS 650D color performance inherits the consistent imaging style of Canon camera. Novices can use the camera's automatic white balance setting with confidence.

The key setting is reasonable, and EOS 650D is simple to operate.

Exposure adjustment of EOS 650D

Holding Canon EOS 650D, the finger of the right hand can be naturally placed on the shutter button, and the thumb of the right hand is just placed at the position of the dial wheel. Although the Canon EOS 650D is small in size, it will not be difficult for both male and female users to hold it, but it is more suitable for women to hold it.

â–² Basic posture of holding the camera

When Canon EOS 650D is in position A or S, you can adjust the aperture size or shutter speed by turning the dial wheel. To adjust the exposure compensation, you need to press the exposure compensation button on the back of the fuselage, and then dial the wheel to adjust.

â–² To adjust the exposure compensation, just press the button+dial wheel.

Although this mode of operation is not as good as high-end SLR cameras, it can control the aperture (shutter) and exposure compensation separately, but the speed will not be slow after skilled operation.

EOS 650D sensitivity adjustment

Although it is an entry-level SLR camera, the independent buttons of Canon EOS 650D can be said to be designed at the point, and there is an independent ISO button next to the shutter button.

â–² Press ISO key+left and right control keys.

When setting the sensitivity, just press the ISO key, and then press the left and right keys in the direction keys to adjust. It should be noted that you can only use the left and right keys to adjust the sensitivity. Although there are two rows of sensitivity, you can't choose quickly with the up and down keys. Of course, for EOS 650D, you can directly use the touch screen to select the sensitivity.

White balance adjustment of EOS 650D

In addition to aperture, shutter, exposure compensation and sensitivity, white balance is also a parameter that is often adjusted. Canon EOS 650D, like sensitivity, also has a special white balance adjustment button. The button is the up key in the direction key, marked WB.

â–² White balance adjustment method

After pressing WB key, press left and right keys to set different white balances. For the setting of custom white balance, you can first take a photo of a white reference object in the preset environment, and then set the photo as custom? White? Do it.

Continuous shooting selfie adjustment of EOS 650D

For selfie continuous shooting, Canon EOS 650D also has a special button. There is a continuous shooting icon on the left key of the direction key, which is the continuous shooting selfie mode key.

â–² continuous shooting selfie of Canon EOS 650D is very convenient.

After pressing the shooting mode button, you can adjust the modes of single shooting, continuous shooting, delayed selfie and remote shooting by selecting the left and right keys.

As for the time to delay the selfie, the last option after pressing the shooting mode button is the clock C and the number. Press the up and down keys in this position to select the countdown time.

Overview of control efficiency:

Canon EOS 650D has prepared independent buttons for common settings, and the detailed settings are also very easy to adjust. The layout and settings of keys originated from 600D are indeed very reasonable, and no changes are needed. In addition, EOS 650D has a touch screen. Let's take a look at the effect of touch screen operation.

${PageNumber}

EOS 650D provides the first efficient touch screen for cameras.

EOS 650D touch screen is very different from other cameras. This is a capacitive screen, just like our mobile phones. Therefore, the most intuitive feeling for the author is that this touch screen responds very quickly, much like the feeling that I love crazy 4.

â–² Touch flip screen of â–²EOS 650D.

Let's watch the operation video of the touch screen. Let's start with a video of parameter setting:

Let's shoot another video with the touch shutter:

Finally, the video of playing back the photos:

Through this touch screen, the author can quickly adjust various parameters, and the playback of browsing photos will feel very smooth. Up to 4: 00 multi-touch can enlarge photos like a mobile phone, which feels good. There have been many cameras with touch screens before, but I have been reluctant to use touch screens because they are not easy to use. The touch screen of EOS 650D makes stubborn authors think that touch screen is such a thing? Reliable!

Let's take a look at the proofs taken by EOS 650D:

â–² Scenery sensitivity: ISO 200 focal length: 50mm shutter: 1/500s

â–² Portrait sensitivity: ISO 200 aperture: F2.8 shutter:1125s

â–² Indoor sensitivity: ISO 100 aperture: F 1 1 shutter: 2.5s

â–² Night sensitivity: F4 ISO 400 aperture: 1/60s

â–² Cat sensitivity: ISO 1600 aperture: F3.5 shutter: 1/500s.

Canon EOS 650D video focus has been significantly improved.

SLR shooting video imaging is very good and the effect is profound. However, due to the need to lift the reflector when shooting video, the phase difference focusing system of SLR camera has failed. Therefore, when shooting video, the focusing speed of SLR is very slow, and it is impossible to achieve real-time focusing. However, EOS 650D applies phase difference focusing pixels to APS-C size sensor for the first time, and EOS 650D can realize phase difference focusing+contrast focusing when shooting video.

Let's watch a video shot with EOS 650D autofocus tracking:

â–² Canon EOS 650D focus tracking effect is very general.

From the video, we can easily find that it is difficult to ensure that the subject is always in focus when the subject keeps rushing out of the focal plane. It can be seen that although the Canon EOS 650D adopts phase difference+contrast focusing, it is still difficult to guarantee complete focus tracking for objects with slightly faster moving speed.

Let's take a look at the focusing effect of EOS 650D when shooting video:

The autofocus effect of EOS 650D shooting video is still very good. With EF 50mm F 1.4 USM lens, you can focus quickly, but there is still a slight respiratory effect.

Let's compare the focusing video of Nikon D3200:

By comparison, we find that the video focusing of EOS 650D is much better than that of SLR only by contrast focusing.

Although I didn't get the EF-S18-135mm f/3.5-5.6 ISTM and EF 40mm f/2.8 STM lenses, I tried these two lenses at the EOS 650D evaluation seminar. See if the STM lens used for EOS 650D shooting video will be perfect. The following two videos were shot with ef-s18-135mm f/3.5-5.6 isstm.

From the actual shooting, we found that even using STM lens is inevitable? Respiratory system effects? Just better than USM lens. By the way, if you buy EOS 650D with EF-S 18-55, the speed and sound of the range hood will be unbearable when the video is focused.

Video evaluation summary:

Using Canon EOS 650D to shoot video must be equipped with USM or STM lens. If you must shoot video with EOS 650D, try not to focus on high-speed moving objects. Generally speaking, the focusing speed of EOS 650D shooting video can be said to be the best in SLR cameras. It's just the road of video shooting with SLR cameras, and it needs to go further.

Evaluation summary: EOS 650D is a work of continuous improvement.

Canon EOS 650D does not upgrade pixels, but it brings very good imaging effect. The imaging quality of EOS 650D can rank first in the entry-level SLR.

Functionally, EOS 650D is also constantly improving itself. The upgrade of the focusing system allows the SLR to shoot video by going up one flight of stairs; With the addition of hand-held night scenes and other functions, I feel that Canon's three-digit series is getting closer and closer to primary users.

Besides, the most important upgrade? The addition of touch screen really makes the author feel the charm of a useful touch screen. I believe beginners will like this smart phone-like operation very much. It can be said that various upgrades of Canon EOS 650D make this new SLR closer to primary users.

Purchase suggestion:

At present, the price of EOS 650d 18-55 sets is around 5700-6200. If you are a user of 600-D, the parameters of 600-D are out of date in the current entry-level SLR, so there is absolutely no need for people with 600-D to upgrade 650D-D. As for users who have bought SLR for the first time and have no plans to upgrade in the future, the author still thinks that buying a new one is not buying an old one, but the price of 650d is relatively high at present. I suggest you wait for a while and reduce it to less than 5000 yuan.

In addition, it is highly recommended that you buy the 18- 135 STM kit of EOS 650D. Because the speed and sound of the lens 18-55 will drive you crazy when shooting video.
