Photographer host

Your question is very detailed and specific. There is a great struggle between 5D4 and A7M3. So, which one suits you best? According to your specific entanglement, let me talk about my views and suggestions.

To be honest, if you are a photography enthusiast, it is obviously more worthwhile to buy Nikon D850/Z7 and Sony A7R2/R3/R4 with high pixels than Canon 5D4!

If you are not a person who makes money by photography, but you are really obsessed with photography, then Sony A7R2/R3 is obviously worth starting with!

First, you said that you are a layman, don't be a mage, and have no ability to be a great god.

However, you are so entangled.

Well, personally, I think it's better for you to buy a Huawei mate30 series mobile phone as the main camera and talk for half a year.

Second, if you don't just need to use it, in fact, these two fuselage are not recommended.

1, Canon 5D4, is the hard currency of wedding industry, and also the main equipment of photo studio and photography studio.

If you are in the wedding industry, or in a photo studio, you used to use Canon, and now you continue to buy Canon 5D4, there is nothing wrong with it.

2, Sony A7M3, in fact, for most photographers, the camera function is equal to zero.

Most photographers, or photographers, hardly take pictures.

For photographers, the pixel of Sony A7M3 is too low, which is obviously not as good as Sony A7R3 or A7R4.

Most photographers, to put it bluntly, are landscape photographers.

Landscape photography enthusiasts, with high pixels and large tolerance, are definitely just needed.

If you are a portrait photographer, 6D2 or EOS R is more suitable for you. It can even be said that in fact, Canon 200D is enough.

If you are a landscape photographer, there are obviously cheap high-pixel models like Sony A7R2 and high-pixel models like Sony A7R3, which are very cost-effective.

Fourth, if you are a self-media user, APS is actually more practical.

For self-media users, APS is indeed more practical and easier to use.

To sum up, if you are going to engage in professional photography or professional photography, 5D4 or A7M3 are good choices.

However, if you are not engaged in professional photography, then 5D4 or A7M3 are not suitable for you.

For non-professional photographers, photographers, photographers and self-media users, it is really not recommended to use 5D4 or A7M3.

I suggest you consider Sony A7R2/A7R3, as well as Canon 6D2 or 200D, M50 and EOS RP.

In fact, the subject conducted a detailed and sufficient investigation between 5D4 and a7m3, and basically had a preliminary thinking about what kind of machine to buy. Personally, I am a Canon SLR user, but in view of the situation of the subject, I suggest you start with Sony a7m3. Why?

The purpose of the subject is very clear, that is, I like photography for my own use. The purpose of this use is different from taking pictures and homework. For your own camera, there are several points to consider:

1, the picture quality is enough. From this point of view, both machines can meet the needs of the main body, both of which are Quan Huafu, with perfect image quality and functions. Canon and Sony have their own advantages. Canon's straight color is pleasing to the eye, while Sony's tolerance is higher.

2, easy to carry. This is a key issue. Many photographers devote themselves to full-frame SLR and Dayuan, but few really find that they can take pictures with this equipment at any time. The huge volume and heavy weight have greatly dampened their enthusiasm for shooting and creating. Although SLR still has advantages in stability at present, it is absolutely unnecessary for enthusiasts to use the ultimate performance. The requirement of equipment stability is not as high as that of working machine, but portability is a very big requirement. Some people say that a7m3 is not small, and the lens is also a "giant single", but it is much lighter than a SLR like 5d4, especially for some small lenses, the volume and weight will be controlled within a very reasonable range. For ordinary photographers, a camera that can be taken out and easily taken out is a good camera.

3, the function is easy to use. Compared with 5d4, a7m3 has lower learning cost. What you see is what you get when you take a view. A mirrorless camera can see the exposure and focus at a glance, which is convenient for observing the final situation of taking photos on evf or on the screen, while a 5d4 optical viewfinder requires the photographer to have some experience. In terms of focusing, the high-speed focusing performance of a7m3 has surpassed that of SLR in some aspects, which is very easy to use, especially focusing with eyes. It is the best focusing performance in the current camera system, and the experience is excellent. Although the optical focusing of 5d4 still has some advantages in response speed, the overall experience is definitely worse than that of intelligence, and it is more convenient for non-working purposes without anti-focusing. Some friends say that Sony's menu is complicated and difficult to master, but it can be overcome. By setting a custom menu and classifying common settings, you can get started easily.

4, the lens. Canon EF lens group is extremely rich, and it is already a very mature system, and the price is also relatively cheap in Bisogni. However, you should be able to understand that the future development trend is still no anti-model. Canon's key lens system has turned to RF card lens, and EF lens can only get older and older in the future. From this point of view, if you want to keep a camera system for a long time, the non-reverse model is a good choice. In the non-reflex system, Sony lens is perfect. Although not as rich as the SLR lens system, it is commonly used. Expensive, by the way, many friends will say that Sony lenses are expensive, but we can have a look. Which is cheaper, Canon RF lens or Nikon Z lens? Sony is actually not expensive without a mirror. Start with the usual ones, and then slowly enter the camera when there is demand. There is no need to buy them all at once. In addition, Sony can also consider using deputy factory lenses, so that the cost performance will be highlighted. There is no anti-era, and the lens of the deputy factory is far less unreliable than that of the SLR period. Focus, speed and image quality are very close to the original factory, which has many unique advantages. The deputy factory is no longer so "deputy".

To sum up, I personally think that as an ordinary photographer, Sony a7m3 will be more suitable.

These two machines are used for work. Canon's advantage is that the leather is durable and basically won't break. Sony's advantage is that it is powerful, but the probability of problems is greater than Canon's, so it is necessary to put a spare machine in the bag. Otherwise, it's really a little uneasy. Canon's screen is very easy to use, with good direct color and high film output rate. The work of handing in the film on the day of shooting was done with Canon. Sony's screen is very bad, and you need to connect an external monitor to see if the exposure is correct, especially when shooting, choose HIG or slog2. However, there is a lot of space in the later period, and friends who like color matching choose Sony. For photos, Canon is the favorite of the old mage, because it feels excellent, the portrait color is pleasing to the eye, the operation is reasonable, and the ergonomic design has also been unanimously recognized by users. Sony's body is small, the grip is not good, and the layout of buttons is not good. Users need to make settings according to their own habits to meet the shooting needs of multiple scenes. I hope to redesign the menu and operation panel later. The rest is not a problem. These two machines are the main force in the market.

I have been using a Canon camera since I started photography. By chance, I got into a Sony micro camera. I feel the convenience and neatness of photography from practical application. In particular, the "peak focus" function has brought great convenience to users who are obsessed with the lens of the old film machine. With the growth of age, small and light equipment is needed. Recently, I took out the Canon camera, recovered the funds and completely changed the door-I went to Sony a7R3.

I bought Canon 500D in the summer of 2009, changed it to 6D in the summer of 14, and changed it to Sony A7M3 in the summer of 18. The lens is connected to the lens of Canon EF port with Sigma MC- 1 1 adapter ring. The electronic viewfinder is very practical, and the highest endurance record is 2650 a day (in RAW format). After using the micro-bill, you will never think about 5D4 again. Now I just feel that Sony sometimes tends to be green, and then switch to Canon 70-200 2.8 lens to shoot the face vertically, which is easy to pull the bellows, and everything else is fine.

First, compared with performance, 5D4 is a better choice in terms of color and professionalism. I've used it, too. The color and shooting are excellent. If you take more photos, you'd better choose 5D4. A7M3 has great advantages in the fuselage. His fuselage is very light. At the same time, it has the function of focusing eyes, and it is also very stable in video shooting. If you shoot more videos, you can choose A7M3.

The second type: just a little simpler, buy that new one, the newer the function, the more complete it is.

Shooting people like Canon and video Dossoni.

For professional cameras, image quality is undoubtedly the most important place for consumers, which is directly related to the quality of the final photos. Canon 5D Mark IV and Sony A7R2 are both professional-grade cameras that sell well in the market. The same positioning and similar prices often make it difficult for consumers to distinguish when buying. Today, I will compare the performance of these two cameras in detail to see who is the real "king" of image quality.

"Image quality" is actually a general term. If subdivided, it can be roughly summarized as the following four points: detail performance at low sensitivity, noise control performance at high sensitivity, tolerance performance under overexposure or underexposure, and color performance under JPEG direct exposure. Only by doing these four things well can we say that this camera has excellent image quality.

Before making a detailed comparison, let's get to know the two players who are about to play. EOS 5D Mark IV is the latest professional Quan Huafu SLR camera released by Canon. Compared with the previous generation, the camera has successfully raised the pixel level to 30.4 million, and with the help of DIGIC 6+ processor, the performance of high sensitivity and noise control has also been greatly improved. At the same time, 4K video shooting, touch screen design, Wi-Fi/NFC and other high voice functions are all configured on 5D Mark IV.

Next, Sony A7R2, a mirrorless camera with the highest pixel at present, is equipped with a back-illuminated CMOS sensor with about 42.4 effective pixels. Due to the special structure of the back-illuminated sensor, it can receive light better in the dark environment, which greatly increases the shooting effect in the low light condition.

Comparing the two cameras together, the Canon 5D Mark IV looks more rounded, and the wide handle provides a comfortable grip experience. Sony A7R2 emphasizes portability. Because there is no mirror structure, the volume of the whole machine is much smaller than that of SLR. But at the same time, the camera's grip will be sacrificed to a certain extent.

In this test, we all used their standard lenses.

In order to make the comparison result more fair, we have adopted the standard lens group of each family in the choice of lens. Canon has EF 24-70mm f/4L, USM, and Sony has FE 24-70mm F4 ZA OSS. The same focal length and lens aperture can ensure that the parameters of the two are completely unified during the test, and the comparison is more intuitive.

Contrast 1: Detail expression under low sense

Many consumers think that the higher the pixel of a camera, the better the picture quality. In fact, this is completely wrong. Because pixels only represent the size of the photo, they can't explain the quality of the photo. Although in the same scene, the higher the pixel, the higher the theoretical resolution, but whether each pixel is stereoscopic will test the overall level of the sensor. In fact, according to the pixel per inch of the mobile phone camera, the pixel of Quan Huafu camera can easily exceed 100 million, but everyone knows the quality.

In order to get better photo quality, Canon 5D Mark IV and Sony A7R2 adopted different strategies. 5D Mark IV is conservative in pixels, using the current mainstream 30.4 million-level sensor. Sony A7R2 is more radical, using a 42.4 megapixel sensor. There is no absolute good or bad between the two choices. We speak with facts.

Low sensitivity detail test area

The author puts two cameras on a tripod at the same time, screws the lens to the 50mm end and fixes the aperture to F5.6 to gradually improve the sensitivity, and compares the details of the two cameras in the low sensitivity range.

By comparing the details of 100%, we can find that the details of the Canon 5D Mark IV on the right are obviously better, not only in definition, but also in fineness, which is much better than the Sony A7R2 on the left. Although A7R2 has more pixels and higher resolution than 5DM Mark IV, Canon's 5DM Mark IV completely wins in detail.

Note: Due to the high pixel of Sony A7R2, the photos taken in the same place and the same focal length will be larger than the Canon 5D Mark IV after being enlarged by 100%, which will not affect our observation of the details of the photos. The same below.

Comparison 2: Noise control performance under high sensitivity

In addition to low-sensitivity performance, high-sensitivity noise control is also an important part of image quality evaluation, because it is impossible for us to take pictures in a well-lit environment every time. Once we encounter night or indoor environment, we need to improve the sensitivity of the camera to get accurate exposure. Next, I will take pictures of Canon 5D Mark IV and Sony A7R2 in dark environment to see how they perform in low light environment.

High sensitivity noise control test area

Just like before, fix the camera on the tripod, screw the lens to the 50mm end, fix the aperture to F5.6, gradually improve the sensitivity, and compare the details of the two cameras in the high sensitivity range.

The test results are also obvious. Canon 5D Mark IV is ahead of Sony A7R2 in the whole process. Even if the sensitivity is raised to ISO 5 1200, which is rarely used at ordinary times, the 5D Mark IV has no wide range of color noise. Since ISO 12800, Sony A7R2 has obvious color noise and low photo usability.

Comparison 3: Tolerance Test

The author's method of testing camera tolerance is very simple. At the same time, the two cameras are set to ISO 100. The overexposed and underexposed photos are taken step by step in the camera's RAW format, and then pulled back by Lightroom software. Compare the later photos to see who can restore more details.

First, let's take a look at the test results of exposure. According to our experience, the overexposure of all cameras above the third gear is not available at present, so we only compare the overexposure within the third gear.

As far as the details of restoration are concerned, both Canon 5DM Mark IV and Sony A7R2 have achieved very good restoration results. The only difference is that Sony A7R2 still retains a small amount of details in the bell highlight area after the third gear overexposure, while Canon 5DM Mark IV is relatively lacking.

Next, let's look at the underexposure. This time, there is a big difference between the two. At first glance, with the increase of underexposed gears, the brightness of Sony A7R2 gradually decreased after being pulled back in the later period, and Canon 5D Mark IV kept very good at this point. Let's look at the restoration of details. At this point, both of them have reached the current top level, and there is no difference. It's just that the automatic white balance of Sony A7R2 has a certain degree of drift in the later period, while Canon is still relatively accurate. Therefore, in terms of tolerance of underexposure, Canon 5D Mark IV wins.

Contrast 4: JPEG direct color

Many people will ignore the color expression of photos when comparing the image quality. In fact, this is also an important part of our evaluation of photo quality. Because many photos in JPEG format are more versatile and shareable than photos in RAW format, especially when the camera has wireless transmission, it can directly transmit photos to friends, so it is very important to see whether the color of photos is good or not.

Because the matter of color is too subjective, the author only gives JPEG photos, which are evaluated by netizens themselves. The following photos are JPEG direct photos of 5D Mark IV and A7R2, both of which were taken by the camera's automatic file. All parameters are the default settings of the camera. Later, the photo size was unified and EXIF information was erased. If you think whose color is good, please vote in the voting column at the bottom.

After reading the contrast test, I believe you have a clear understanding of the image quality performance of Canon 5D Mark IV and Sony A7R2. Generally speaking, the image quality of these two cameras has reached the top level among the current full-frame cameras, but comparatively speaking, Canon 5D Mark IV is superior to Sony A7R2 in details, high sensitivity and exposure latitude. On the other hand, Sony is slightly better than Canon 5D Mark IV in overexposure tolerance.

By the way, here is a simple hearsay: If you play more videos, Dafa is your best choice. If you just take pictures, 5D is definitely the first (only these two models).

In the color of JPEG photos, A is Canon 5D Mark IV and B is Sony A7R2. Look at the relative picture below.
