Review I personally very much like Mr. Zhang Wei, Mr. Zhang
as a senior paragraph player
really bring us too much joy, so it is also honored as a boutique on earth. In the camera world, one of the most talked about products with the greatest momentum recently is the 5D4, which in my mind is considered to be one of the best in the camera world. Overall Canon from the previous 5DS / R Canon has been removed from the toothpaste factory nickname, and constantly released a lot of high-caliber SLR, the latest release of the 5D4 is still no exception.Canon 5D4 can be seen as a balanced concept to the end of a product, remember Canon released the 5D3 slogan is: only the legend beyond the legend. From our evaluation of the overall performance of the 5D4, this sentence basically expresses a positioning of the 5D4 in my mind, nonsense is not much to say, the following to take a look at the detailed review of the 5D4 together.
Gallery will be balanced to the end of the Canon 5D4 real sample appreciation

"Cons
:1. Currently the price is a little bit inflated
2. Power drops off very quickly in real-time framing (you should boost the battery capacity a little bit)
3. 4K video is not supersampled, and you have to calculate about 1.74 Times the lens factor4. did not join the c-log mode
"Review Summary:
After the review always have to summarize the product a little bit, remember a few years ago, everyone unanimously in the spray Canon, said Canon is a toothpaste factory. When that ancestral sensor is used for too long, so it is normal to attract some questions. But from the point of view of the performance of the past few years is quite a bit of a sense of courage. Little by little, slowly through the continuous update of the product to regain the market and praise, this time the 5D4 is in such a trend of the product. 5D4 really did not like the D800 has just released as only by virtue of a function that others can not reach the leader (of course, now by the 5DS to catch up with), but the 5 series has always been the design concept is balanced, balanced, balanced, so in the 5D4 to see is still balanced! . Every part has been upgraded, and the new features that have been upgraded are pretty solid, almost sort of adding some of the new features that Canon has now, and not hiding them. And the addition of full-pixel dual-core CMOS AF to the 5D4 is sort of injected into a powerful hardware configuration, you can not imagine that now Canon's DSLR real-time framing focusing or shooting has been able to be so smooth, micro-single in this area of the advantage of the gradual reduction. So the Canon 5D4 is indeed more balanced in all aspects, with no obvious shortcomings, but that doesn't mean it's mediocre, as all the features can still be maintained at a high level."Buying guidance:
One of the scariest things about a product is that it has no obvious shortcomings and is suitable for any subject matter. Because that basically fulfills most people's needs, there's absolutely no regret in recommending this one when others don't know what to buy.So, do you think it's worth buying? Definitely worth buying? But is it a buy now? This point I take a negative attitude, the official announcement on the day of the launch of the single body 26,599 yuan, the price is definitely a bit inflated, and today the dealer price has been given 24,999 yuan, almost in such a short period of time dropped almost 2,000 yuan, so we wait for six months to get it, absolutely will be better prices will appear, Canon's production capacity is no problem, not subject to the constraints of the other family (Sony) sensors. As long as the yen exchange rate doesn't take a historic spike, then the 5D4 will be reasonably priced.
"Canon EOS 5D4 exterior
:The Canon 5D4 has a nice overall feel in the hand, and it's also a bit lighter than its predecessor. That's rare, of course. In addition there are 4K and real-time viewfinder and WIFI transmission and other heat-producing big players, so the heat in the body when in use must increase, but as far as we know, the Canon side in the design process deliberately pay attention to the problem of heat dissipation, with new materials, so the heat dissipation situation is still doing very well.
"Pixel count breaks through 30 million, picture quality improved significantly
We know that the Canon 5D Mark IV uses a new 30.4-megapixel sensor, which breaks through 30 million pixels, an increase of about 8 million pixels over the 5D Mark III. Here's a comparison of the 5D Mark IV and 5D Mark III with the 24-70mm F4 lens, to see how much of a boost the higher pixel count brings:
▲Resolution Comparison Test
Through the comparison of the real-world images, we can see that the Canon 5D Mark IV has much better image detail, especially at the edges, compared to the 5D Mark IV, which has a much higher pixel count than the 5D Mark III. In particular, the edge-to-edge resolution is a clear advantage over the 5D Mark III. The higher pixel count results in better image quality when cropping and outputting in post-production, making the Canon 5D Mark IV more suitable for professional photographers who are looking for the best.
"New noise reduction algorithm is effective and ISO6400 is usable
Canon 5D Mark IV not only adopts the DIGIC 6+ processor, but also updates the noise reduction algorithm, which theoretically has a more excellent noise control performance. Here we feel the high sensitivity performance of Canon 5D Mark IV in the actual test. The native sensitivity of the Canon 5D4 is ISO 100-32000, which can be extended to ISO 50-102400.
▲ Sensitivity Comparison Test
By comparing the above, we can see that the Canon 5D Mark IV has richer details at the same sensitivity. The new algorithm effectively reduces the amount of red and green noise, making the image look cleaner and even at ISO 12800 there is no visible noise. It is not easy for the Canon 5D Mark IV to maintain the same level of noise control as the 5D Mark III even after the number of pixels has increased by nearly 8 million, and to have a higher level of sharpness. In daily use, ISO control below 6400 is no problem at all.
"Tolerance improvement is obvious, and the details are rich after adjusting the exposure
In the past, tolerance was not a strength of Canon cameras, but this situation has changed a lot in the 1DX Mark II and 80D. I believe the Canon 5D Mark IV's tolerance compared to its predecessor is also a point of concern, so we conducted a comparison test. To be clear, PS doesn't support the 5D4's RAW files, and the Canon DPP software's exposure adjustment is only 3 stops, so we've only measured plus and minus three stops this time.
▲Tolerance Comparison Test
What's encouraging is that you can visualize the improvement in tolerance of the Canon 5D Mark IV. Apart from the obvious loss of detail that occurs when you increase the exposure by 3 stops and force it to pull back, the rest of the picture is rich enough in detail. Although there is still room for improvement compared to those models with very impressive latitude, we have clearly felt that Canon is making progress. Of course, latitude is not the only factor that affects imaging, and the Canon 5D Mark IV's latitude performance is good enough.
1. Dual-pixel RAW optimization
The Dual-pixel RAW function is definitely the most prominent feature on the Canon EOS 5D4, and it's mainly due to the addition of the Dual Pixel CMOS AF technology to the Canon EOS 5D4.
Canon's All-Pixel Dual-Core CMOS AF technology is based on a new sensor design derived from the fact that there are two photodiodes under each individual pixel***, and when focusing, the two photodiodes under the individual pixel, A and B, perform a fast phase-difference focusing, and then the image signals of the two photodiodes can be output as a single pixel when imaging.
So Canon's technology can capture two parallax images at once, and the Dual-Core RAW Optimization feature is based on this principle. So when full-pixel Dual-Core RAW shooting is enabled, Dual-Core data and subject depth-of-field information is recorded (just as people use their left and right eyes*** to record the same information). Based on this information, the Full Pixel Dual-Core RAW Optimization feature allows for multi-dimensional image processing and enhanced image quality when using Digital Photo Professional for later RAW development.
First of all, this feature isn't automatically turned on by default; there's a separate option to turn it on in the on-camera menu, but don't forget to set the image quality to shoot RAW before turning on All Pixel Dual Core RAW.
It's worth noting that with Full Pixel Dual-Core RAW turned on, the file size of Dual-Core RAW will be twice as large as regular RAW, and it will also slow down continuous shooting.
What you need to pay special attention to is that in Dual-Core RAW mode, ①Continuous shooting is not available in Live View mode ②HDR, Multi-Exposure, and B-gate are not available ③Digital Lens Optimization is not available.
After opening, you can also see a DPR icon in the menu interface, which indicates that it is currently in the full-pixel dual-core optimization mode.
After turning on Dual Pixel RAW optimization, it's time to test the real-world shooting. Here's the main test of resolution compensation and defocus offset function:
①Resolution Compensation:
Resolution Compensation is not a simple sharpening of the whole picture, but rather, it's a sharpening and offsetting process of the focus point based on the information of the phase difference of the subjects recorded by the Dual Pixel RAW. and offset processing.
This function is actually very simple to use, we open the Full Pixel Dual Core RAW tool in the DPP software, click on the image fine-tuning button to adjust the position of the focal plane, and then click on Save when the adjustment is complete.
With this feature, we can save some of the unused "waste" photos due to focus shift.
2) Bokeh Shift:
When we use a wide-aperture lens, the subject may be obscured by the bokeh in the foreground, which is usually deleted as "waste". With Bokeh Shift we can move the bokeh in the foreground to reduce the amount of bokeh blocking the subject.
Likewise, we can adjust the direction of the bokeh offset in the menu
Overall, the adjustments are quite noticeable. Although these features can partially save us from a "wasted" image, the range of adjustments they can make is still very limited. However, the scope of these adjustments is limited, and there is no guarantee that they will be successful in saving every photo. Therefore, the important thing is to try to avoid mistakes in the pre-shooting stage. However, I still hope that camera manufacturers to develop more features like this, so that you can minimize the difficulty of the shooter to improve the success rate of the photo. This will allow more people to enjoy photography and to discover and record the beautiful moments around them.
"2. Digital Lens Optimization
:In the 5D4's menu, you can see the new Digital Lens Optimization feature, which was originally available in the DPP (Digital Photo Professional) software. It's now fully implemented in the 5D4.
Previously, the 5D3 had peripheral brightness and chromatic aberration correction, but this time there's distortion correction for wide-angle lenses and diffraction correction for small-aperture shots.
But at the same time, note that after turning on the digital lens optimization continuous shooting speed will become slower, I guess the reason is that the processing data becomes more, so it will affect the continuous shooting speed, should be improved later.
With Digital Lens Optimization turned on, the previous two options are automatically hidden, since they're already included in Digital Lens Optimization. Another thing to note is that Canon's optical optimizations (peripheral brightness correction, chromatic aberration, distortion, diffraction) are based on official lens data, but in the future all Canon lenses will be released with a chip built in to record the lens data, so you won't need to update it to use the optical optimization data from any of the new lenses. Digital lens optimization will need to be registered through the EOS Utility.
"3. New white-priority white balance mode
White-priority is a new white balance mode that eliminates the effects of incandescent lamps and other light sources and restores as much white as possible for a clean image. The former Auto White Balance has a new name, Ambience Priority.
Tap into the white balance options in the menu, then dim the INFO button to switch between Ambience Priority and White Priority, while the other white balance modes remain unchanged.
▲Ambience Priority mode
▲White Priority mode
After turning on the two different white balance modes, the contrast in the same scene is very obvious. The overall environment of the shooting environment is supposed to be on the yellowish side, and I can see that the color tone is much cooler in the white limited mode. So my personal guess is that turning on this mode will automatically make the white balance of the picture a bit on the cooler side. Still, it's useful for some environments with a lot of yellow light sources.
"4. Not just 4K video but also 4K screenshots
Canon's lineup has always placed a lot of emphasis on video capture capabilities since the 5D2, and the 5D4 continues this tradition of strength with the inclusion of 4K video capability in Motion JPEG compression format (a relatively large amount of data, which is kind of a point that could be improved upon in the future). But unlike the Canon EOS-1DX Mark II, the EOS 5D4's 4K video is only supported up to 30P (NTSC).
But we also learned that this time around, the Canon 5D4's 4K video takes a pixel area of 4096×2160 in the center and reads it pixel by pixel on a point-to-point basis, meaning it's not a full-pixel capture and then compresses it (supersampling), so the downside is that when you're shooting 4K video, you're shooting a narrower perspective because you're capturing a portion in the center of the frame. You also end up with a lens factor of about 1.74x. In the 1080p format, however, a supersampling method of full-pixel capture and then compression is used.Meanwhile, if you select High Frame Rate Movie Shooting in Video Mode's Movie Quality, you'll be able to shoot 120p video at 1280 x 720, making it easy to upscale for later use.
To make it easier for more professional teams to use the Canon 5D4 to shoot video, the Canon 5D4 also includes a feature first seen on the 80D in video mode, which is the adjustment of video autofocus speed and short film servo focus sensitivity.
But if you want to enable these two features, you first need to be careful not to select "face recognition + tracking" mode in the autofocus mode, because both features are not available in this mode.
The autofocus speed, as the name suggests, is the speed at which the focus switches between the two modes when you manually change the focus, and it offers ten levels of adjustment. Different effects can be achieved by adjusting the shutter of the autofocus speed. In the video below we are able to see a comparison at the two most extreme autofocus speeds.
The sensitivity refers to how well it recognizes objects that pop into the frame when the subject is already in focus. If you want to keep the original focus on the subject unchanged, you can choose to adjust it to the left (i.e. not sensitive), again with a video to show you the difference between the two limits.
Finally, it's time to talk about the screenshot function that's so useful in the 4K video feature, as we all know that a single frame of 4K video is equivalent to a still photo of about 8.8 megapixels. Before a lot of cameras with 4K features have video screenshot function (such as Panasonic GH4), in some conditions in order to ensure that the shooting is not missed some fleeting images, can be achieved by shooting video and then intercept a single frame.
And
and the Canon 5D4 is capable of 4K 30P video capture, which equates to about 30 frames per second of continuous shooting, which equates to 7 frames per second faster than when shooting full-size stills, allowing for more efficient capture of photos.Find a 4K video in the playback function, press play and pause it at any time to see the following image.
The icon above the cut logo is the option to capture a single frame of video.
At the end we get a 4096 X 2160 resolution photo without having to affect the original video, and the stills will be stored as new photos, though the only shame is that this 8.8MP photo doesn't come with EXIF information.

"5. New WiFi transfer function
Canon has also added WiFi to the 5D Mark IV this time. Connecting wirelessly with a smartphone or tablet, you can remotely display real-time shooting, as well as browse and transfer captured images. Connect with Wi-Fi enabled laptops and printers to perform a variety of operations or prints wirelessly. Images can also be backed up to the Canon Image Storage Connect Station CS100 or uploaded directly from the camera to cloud storage via "Canon Image Upload".
After enabling WiFi, select a connection method. Then open the Canon Camera Connect app on your mobile device to connect to the camera.
Remote camera shooting is highly practical as you can adjust aperture, ISO, and exposure compensation in real time on your mobile device, in addition to simply pressing the shutter.
In addition to being able to remotely control camera shooting for more flexible shooting angles. You can also transfer the captured photos to your smart device in time to share them with others or upload them to social networks.
"Second-generation 61-point focusing system for stronger focusing performance
The Canon 5D4 utilizes the same 61-point, high-density mesh-array AF-II focusing system as the EOS-1D X Mark II, with 41 crosshair focusing points, and the full 61-points support an aperture of F8, which means that a constant F4 lens with a 2x booster lens can be used with all the focusing points. can also use all of the focus points.
The Canon 5D4's 61-point focusing system has a much wider range of autofocus points than the 5D3's. The center area extends vertically by about 8.5 inches. The center area is extended vertically by approximately 8.6%, and the peripheral area is extended vertically by approximately 24%. The ability to capture subjects more efficiently improves mobility for shooting dynamic subjects.
Meanwhile, the 5D4 is also equipped with an approximately
150,000-pixel RGB+infrared metering sensor. The high-megapixel metering sensor is capable of capturing the viewfinder frame as an image and detecting the subject's color, the person's face, and so on. It transmits rich information about the subject to the respective dynamic system to improve the accuracy of auto exposure, auto white balance, auto focus, etc. The metering sensor is divided into 252 zones for metering. The DIGIC 6 digital image processor (a separate processor) dedicated to metering processing and a new metering algorithm analyzes color distribution, subject color, and movement within the frame, improving subject recognition performance.Using data from the built-in approximately 150,000-pixel RGB + IR metering sensor, the EOS iSA System
Intelligent Subject Analysis System (IAS)
analyzes not only the brightness of the subject, but also the subject's position, color, etc. The information derived from the IAS is used for EOS iTR AF (Intelligent Tracking and Recognition AF). The information from the EOS iSA System (Intelligent Subject Analysis System) is used in autofocus systems such as EOS iTR AF (Intelligent Tracking and Recognition AF) to improve face recognition. Focus performance test: This time, I took the opportunity to test the Canon 5D4's focusing and continuous shooting functions during an equestrian shoot, and found that the increased focusing area is really helpful for shooting sports subjects. And the continuous shooting speed of 7 frames per second is also sufficient for shooting equestrian subjects. The automatic face recognition function has a very high success rate in some static scenes, but it can't reach 100% success rate in high-speed sports.
