Full-featured, simple and easy to use Sony single battery A37 comprehensive evaluation.

IT 168 evaluation single battery does not lose SLR in function and image quality, and continuous shooting's performance is far better than SLR. Now, Sony, which plays a leading role in radio and TV stations, has officially released a new entry-level radio station-Sony? 37。 As? An upgraded version of 35, Sony? Has the picture quality improved? What changes have been made to the functional parameters? Let this in-depth evaluation tell you.

Before the evaluation, let's have a comprehensive understanding of Sony from the appearance and function. 37:

▲ Sony single power? 37 main functions

Sony? The 37 is equipped with an Exmor APS high-definition CMOS image sensor, and the effective pixel is 1665438+ million. In pixels? 37 relative? 35 (16.2 million pixels) has not been improved, but on the basis of the original panoramic scanning, high-speed continuous shooting, hand-held night scenes and photo effects, Sony? The 37 also adds smart portrait composition, clear image zooming, 3D photo taking and other functions, which is much higher than similar SLR in continuous shooting and functional interest.

▲ Sony? 37 (left) looks the opposite? 35 (right) There have been some changes, and the overall height has become a little higher.

Sony? 37 appearance relative? Some changes have taken place. The logo and model of 37 were moved to the same side of the fuselage, and the handle groove where the index finger was placed was further deepened. Even if the index finger is placed on the shutter when held by one hand, the fuselage can be well balanced only by the middle finger. At the same time, the leather ornaments of 37 are also relative? Much better, the leather feels more comfortable and the texture of the fuselage looks better. 35 plastic feels much better.

▲ Side of the handle

As you can see from the side, Sony? The thicker handle and the deeper groove can help the user to grasp it better? 37。 Electronic viewfinder is much more prominent than SLR, so it looks longer.

▲ Sony? 37 rear view

Sony? The design of buttons on the back of 35 continues the design style of the previous generation products. The arrangement of buttons has not been adjusted, but the skin of thumb has become much more delicate. With what? 35' s 920,000-pixel LCD screen is different. 37 is also equipped with a mainstream folding screen, which can be folded to 135? Fold down 55? It is very convenient to shoot from multiple angles. However, the screen pixel is only 230,000 pixels, which makes a certain discount on the display effect.

▲ The screen is folded.

▲ Screen folding down effect

▲ Sony? 37 top button distribution

On the mode disk, Sony? 37 adds a separate mode for 3D photography and video recording, but slightly changes the D-RANGE key near the shutter button to the ZOOM key (clear image zoom). After pressing this key, you can double the zoom effect by using the main dial wheel or the arrow keys on the back (described later). In addition, the position of the on-off key and the design of the camera key have not changed.

▲ Sony? 37 side

Is the flash on button on the left side of the fuselage still extended? The design of 35. At the same time, the MIC interface, HDMI interface, video output interface and remote control terminal are all on the left side of the fuselage. In order to make the fuselage look less introductory, the mode dial of the 37 has also changed from silver to black.

▲ Sony? 37 data interface

▲ Sony? The bottom of 37

Sony? There is a metal tripod hole at the bottom of the 37, 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, the warranty certificate code and the body code must be consistent before the warranty can be guaranteed)

▲ Card bin and battery bin

In addition, batteries and battery positions are located in Sony? The bottom of the 37 does not affect the replacement of the battery and SD card after installing the quick-loading board.

▲ Sony? 37 NP-FW50 batteries were used.

Sony? 37 adopts NP-FW50 lithium-ion rechargeable battery,1080mA. When fully charged, the electronic viewfinder takes about 450 photos and the LCD (CIPA test standard) takes about 500 photos, which is not much different from the entry-level SLR.

Sony's The overall material, shape and key layout of 37 show that it is an entry-level product, but it has improved a lot compared with the previous generation. But the only drawback is, Although equipped with a more convenient folding screen, the 37 has only 230,000 pixels, which is much worse than the previous generation's 920,000 pixels.

Sony? 37 resolution test performance is average.

Sony? The effective pixel of 37 is 1665438+ million, although the opposite is true in pixels. 35 instead of 654.38+ megapixels, but? BIONZ image processor of 37 will optimize sensor imaging, so? What's the improvement? Might as well through the next test to verify it.

Do we use Sony in the resolution test? Equipped with a 50mm F 1.4 lens, 37 took samples of ISO 12233 resolution standard board (4000 lines) at each aperture, and tested them with Imatest software, and finally got the best resolution value. The test results are as follows:

▲ Sony? 37 optimal resolution

Through the measurement of resolution, it is found that Sony? The best resolution of 37 is around 2000 lines, which is medium among cameras of the same level, but what do you think? Imaging from the center to the edge is relatively uniform. In order to avoid the influence of internal sharpening, also look at Sony? What is visual resolution?

▲ Sony? 37 Best visual resolution

It can be seen that in terms of visual resolution, Sony? The horizontal resolution and vertical resolution of 37 are close to 2400, which is much higher than the score of Imatest software. The reason for the low running score may be the dark exposure of the test samples. However, these are only individual test results. Do we have to watch Sony? What is the comprehensive performance of 37 in real shooting?

Sony? 37 clear real photos with rich details.

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.

▲ Clarity test environment

We use Sony? This photo was taken in a standard evaluation environment. The lens used is 50mm F 1.4, the shooting parameter is F8 aperture under A file, and the sensitivity is set to ISO 100. For the convenience of comparison, we 100% cut off four parts of the sample (the red box area above) for observation.

▲ Sony? 37 clarity proofs 100% screenshot

Judging from the 100% screenshot of the face, Sony? The details of 37 are quite good, but some sharp marks can be seen through the algorithm, but it is good for novices who don't understand the later period. And the screenshot of the pen container can be seen, Sony? The expression of color is natural, but the reduction of objects is general, as can be seen from the screenshot of coins.

Editor's comment: Although the resolution test data is average, it comes from Sony? 37, 1665438+ megapixel resolution is enough for beginners. In the ISO 100 sample, we can hardly see any noise in the picture, so? What will happen on other sensitive issues?

${PageNumber}

Sensitivity ISO800 can be tested with Sony A37 high sensitivity.

In addition to clarity and resolution, there is also an important indicator that determines the quality of photos, that is, noise performance at high sensitivity, which is also a matter of great concern to everyone.

▲ Sensitivity test environment

For high-sensitivity performance, we shoot the same scene and then shoot Sony at the position shown in the picture. 37. I believe that no amount of description is as intuitive as looking at the picture directly.

▲ Sony? 37 Rigid width ISO800 is available

Can you see Sony in ISO400 and below? The picture of 37 is very clean and delicate. In ISO800, there is a graininess that can be recognized by naked eyes, but it is still within the acceptable range. However, when ISO 1600 and ISO3200 are used, the details of the picture will be lost with the increase of ISO value, but the number of noise will not increase obviously, but become jelly-like. Until ISO6400, the graininess of noise became more obvious. For what? As far as the overall high-sensitivity performance is concerned, ISO800 is fully available, and ISO 1600 has little problem in emergency use, which is already the same as the entry-level SLR.

Sony? Automatic white balance works well.

Clarity and high-sensitivity imaging are important manifestations of image quality, and? The color performance of 37 is also worthy of attention. First, it depends. Can the white balance of 37 accurately restore the original color temperature of the object? Second, it depends. What kind of theme is more suitable for the overall color tendency of 37.

▲ Color test range

Know Sony? 37 imaging style, in the color test, we Gensonnie? 37 equipped with a 50mm F 1.4 lens, shoot the standard color card (the red box area in the above picture is the color test range), and obtain the final data through imatest software:

▲ Sony? 37 Manual white balance test results 1

This test chart reflects Sony? 37 and ideal value. The part surrounded by gray lines in the picture is Sony? 37. The square color block in the test picture is the ideal color value, and the round color block is the actual shooting value. Among them is Sony? The automatic white balance exceeds the sRGB color gamut by 2 1.5%, and has moderate bright color performance, which can be used for post-processing and direct output. 37 is sensitive to red and blue, suitable for shooting landscapes and portraits.

Meanwhile, Sony? The automatic white balance color temperature of 37 is very accurate, and? The main users of 37 may be the first-time users of a single battery, and the automatic white balance will be used more, so the automatic white balance can accurately show the original color temperature of the picture, which is simple and enough for users!

Image quality summary: Visible Sony? 37 still improve the image quality through BIONZ image processor. Judging from the real shooting effect of definition, the resolution of 37 can definitely meet the needs of beginners, and its high sensitivity performance is no different from that of SLR, plus the easy-to-use automatic white balance, in terms of overall image quality? 37 is a single camera that can shoot everyday.

Sony? The 37 keys are clearly marked and easy to operate.

Is it comfortable to hold an entry-level single battery? Is the key easy to use? The adjustment efficiency of main parameters is not high, which is very important for primary users. Professional functions are very important, but it is important to let users get started quickly.

▲ Sony? 37 Two-handed grip effect

Holding Sony in both hands? 37, the left hand can easily hold the fuselage. What about Sony? 37 is small, so both male and female users will have no difficulty holding it. What about Sony? The fuselage only weighs 448g, even if the battery is added, it will not bring too much burden to the user.

▲ Basic posture of holding the camera

At the same time, when taking pictures, the fingers of the right hand can be naturally placed on the shutter button, while the thumb of the right hand is just placed on the skin on the back of the fuselage. With a slight movement, you can press and hold the exposure compensation button on the top of the machine and adjust the EV value with the front wheel.

▲ Press and hold the exposure compensation key and turn the front wheel to adjust the exposure compensation value to 1/3EV.

Besides, when is Sony? When the 37 is in the A or S position, the front dial wheel on the handle can also adjust the aperture size or shutter speed. To adjust the exposure compensation, you need to press the exposure compensation button near your thumb and toggle the wheel to adjust.

Sensitivity adjustment method

As an entry-level single camera, Sony? Because of the folding screen, there are no multi-function buttons on the left side of the fuselage. Different from some high-end models, Sony directly sets the common functions such as ISO, white balance and continuous shooting/timing shooting on the direction keys on the back, which avoids the problem that users don't know how to set them themselves, and displays the functions of the corresponding function keys with easy-to-understand signs.

▲ Press and hold the ISO key and the up and down arrow keys to adjust the ISO value.

Basically, hold down the ISO key, and you can adjust the ISO value by pressing the up and down arrow keys. If you pursue efficiency, you can also use the front wheel to adjust quickly. From where? 37. Generally, it is set to ISO 100-400 in a well-lit environment, and it is recommended to use ISO800- 1600 indoors, which can reduce the influence of hand shake and avoid high-sensitivity image quality that I really can't accept.

White balance adjustment method

In addition to aperture, shutter, exposure compensation and sensitivity, white balance is also a parameter that is often adjusted. Same as sensitivity, Sony? There is also a 37 white balance adjustment button on the direction key.

▲ White balance adjustment method

The adjustment method of white balance is the same as ISO, just press WB's right shoulder, and then quickly adjust it by the up and down arrow keys or the front wheel. In fact, the automatic white balance of Sony 37 is quite accurate in restoring color temperature. If it is not in the case of extreme color cast, everyone can use its automatic white balance

Continuous shooting/timing setting.

Sony? Continuous shooting speed of 37 is 7 frames per second. If you have children or pets at home, you can use high-speed continuous shooting to capture them, which will make the shooting more successful. And in order to facilitate self-portraits, Sony? 37 also set up a delayed self-timer function for everyone.

▲ continuous shooting, timing shooting adjustment.

After pressing the left arrow key (shooting mode button), you can adjust between single shot, continuous shooting, delayed selfie, stage exposure, single shot exposure, white balance exposure and other modes through the up and down arrow keys. In addition to single shot, you can also make a second choice among various options. For example, continuous shooting can choose high speed or low speed, and the delayed selfie can choose 2s or 10s.

Summary of control efficiency: Even if there are not many independent function buttons, Sony? The main parameters of 37 are basically based on? Button+dial adjustment? Therefore, its control efficiency is not low, and the key function is very simple and practical, so users don't need to think too much.

Intelligent Portrait Composition: Super Combination of Sony Self-timer

It's not just Sony, is it? 37 control, if you have paid attention to the self-timer micro-single NEX-F3 released by Sony before, you know that there is a function called? Intelligent portrait composition? What about Sony? 37 has the same function.

▲ Brake Portrait Composition+Smile Shutter Works

The advantage of intelligent portrait composition is that it can help ordinary users who have no professional portrait shooting experience to automatically take photos closer to the golden composition rule.

For a big problem of party selfies, through Sony? The super combination of 37 face detection+smiling shutter+smart portrait composition-can be easily realized in perfect selfie. Because of this, Sony? 37 will automatically detect the face in the picture, and will automatically shoot after capturing the smiling face. You don't have to worry that there is no one in the camera, and you don't have to worry that the expression can't catch up with the time when the camera starts recording. And smart portrait composition can take a better composition when no one is shooting, so don't worry that there will always be photographers in the picture ~

Seven continuous shooting. Nice speed.

Sony? Although it is also called single electricity, it is different from other brands of single electricity in structure. Because of Sony? 37 adopts a fixed semi-transparent reflector, so it is not necessary to lift or put down the reflector like a SLR when shooting, and it is easy to realize 7 continuous shooting per second.

▲ Sony? 37 photos taken at 1 temple

We can see Sony from the picture above. With the shooting ability of 37 seconds, I believe this continuous shooting speed can definitely capture the lovely side of the baby or pet at home.

What is clear image scaling?

For the small card, it is easy to achieve a larger zoom and can shoot farther. However, if the focal length of the lens is not long enough, it is impossible to shoot further, and the telephoto lens is often large and heavy.

▲ The top of the fuselage? Zoom button? Is there a clear image function on the button?

But for clear images, the optical zoom effect can be about 2.0 times. Like using? The telephoto end of DT 18-55mm F3.5-5.6 SAM with a focal length of 55mm can achieve the effect of 1 10mm (35mm is equivalent to 165mm) by opening a clear image, which is enough to shoot distant objects and reduce the equipment burden. As for the effect of clear images, we might as well look at the contrast effect of a group of scenes.

What is the scaling effect of clear images?

▲ Clear image test scenario

▲55mm telephoto end to take pictures (click to view the original picture)

▲ After the image is enlarged by 2 times (click to view the original image)

If you only look at two pictures on the screen, there is no obvious difference in image quality between them. However, according to the author's test, the image quality of the latter has a certain decline in the original size. In order to ensure objectivity, the author uploaded the original pictures of the above two photos. You can see if such a loss of image quality is within your tolerance. Generally speaking, I think it's safe to share photos online? Clear image scaling? Function, can also reduce the burden of the lens; If the quality is strict, it is best to shoot with a telephoto lens.
