Sony A7R III vs Canon 5D Mark IV

Sony A7R III vs Canon 5D Mark IV – Sony A7R III keeps its legacy alive by incorporating High-Resolution of 42.2 MP Full Frame CMOS sensor as of its predecessor, A7R II. We see A7R III made a long jump in terms of AF system since the camera features 425 contrast detect AF points, which is 400 more than A7R II. But its clash is not with its elder sister, but with Canon 5D Mark IV: one of Canon’s most popular semi professional Full-Frame DSLRs known for its staggering imaging performance. We are much desperate to see the detail specification comparison of Sony A7R III and Canon 5D Mark IV and since after reading this comparison you will also get to know which camera would be a perfect pick for you.

 Image quality

You can see A7R III is the resolution king, it doesn’t have low pass filter, it has dedicated Sony A9’s image sensor so we do expect to get some outstanding quality of images from this High-End Sony mirrorless camera. But the sensor size is nearly equal and you can see that Canon 5D Mark IV offers more pixels area that improves  light collection efficiency so may also see a very close competition in terms of image quality offered by both cameras. But point to be noted, that A7R III comes with back-illuminated Exmor R CMOS image sensor which has gapless on-chip lens design and AR (anti-reflective) coating on the surface of the sensor’s seal glass to dramatically improve light collection efficiency, as a result, the camera will be able to produce low-noise performance and wide dynamic range as well.

AF system

From the table, one can simply measure that Sony A7R III doesn’t give side to Canon 5D Mark IV in the race. But, you should know that 5D Mark IV has dedicated AF technology engineered inside the core that is “Dual Pixel CMOS AF System”, which is Canon’s own registered AF hardware. You can also say that this is at a time is at the peak among the best AF technologies in the imaging world. You should know the role of Dual Pixel CMOS AF system — Actually, while shooting 4K focusing precision is more important than anything else and this award winning AF mechanism helps to offer you precise, speedy Live View shooting AF comparable to viewfinder shooting AF. Sony A7R III, in contrast, using both Phase detect sensor as well as contrast detect sensor means Hybrid AF system. However, this Mark IV is also having Hybrid AF system, but where 5D Mark IV lags behind is its AF points, offering 61 AF points with only 41 cross-type points that is not able to track the subjects from wider area. On the other hand, A7R III is comprised of 399 focal-plane phase-detection AF points that cover approximately 68% of the image area in both the horizontal and vertical directions. And 400 more Contrast AF points compared to its predecessor ( A7R II has 25 AF points) that ultimately increases the AF acquisition twice the faster than A7R II.

Image stabilization

Even if you think taking Tripod to you every shooting location a bit difficult task then you can confidently leave it to you home and head towards to shoot the marvelous subject only when you have Sony A7R III in you hand. Yes this High resolution camera does also have 5-axis images stabilization corrects camera shake along five axes during shooting, including angular shake (pitch and yaw) usually occur while shooting with a telephoto lens, shift shake (X and Y axes) increases as magnification increases, and rotational shake (roll) that often affects video recording. With 5-axis I.S system A7R II can produce crisp and blur free images even while shooting in lowight. But Canon 5D Mark IV doesn’t have I.S so one lens a lens with optical image stabilization to get those crisp and blur free images.

Continuous shooting speed

Sports photographers must be happy seeing A7R III burst speed that is 10fps. Yes! With the help of 10 fps, sports photographers can take advantage of every single frame to seize the subject and capture stunning sports photos. On the other side, 5D Mark IV offers 7fps only.


On the rear side of Canon 5D Mark IV a large 3.2″ 1.62m-dot Clear View II LCD monitor is integrated along with  and  an anti-reflective design for bright, vivid image playback and live view shooting, and its touchscreen interface can be used for intuitive touch-to-focus control and adjusting settings in the menus.


May be the A7R III come with supreme features but its battery is not as strong as Canon 5D Mark IV, because 5D Mark IV allows you take around 1200 shots at a time, whereas Sony finishes off just after taking 650 shots at a single time charge.


One is Mirrorless and other is DSLR. But Sony A7R III all due to its Jaw Dropping specifications leave everyone stunned! Sony A7R III with insane AF system and High resolution is a great option for the photographers who don’t want any argument for image quality. Canon 5D Mark IV is for those who needs an all-rounder camera that can cover every section of photography in Equivalent number.
