The Sony A7S III and Canon EOS R5 are two of essentially the most celebrated cameras of recent occasions with every providing a formidable assortment of high-end options for video shooters, however one is way more geared in the direction of stills than the opposite.
The Sony A7S III’s main goal is taking pictures video and it’s the a lot lauded alternative to the favored Sony A7S II. In the meantime, the Canon EOS R5, which was launched similtaneously the R6, is an actual assertion digital camera that at launch made it clear that Canon had woken as much as mirrorless know-how and was going to begin taking the style severely. It combines groundbreaking 8K video know-how with staggering stills functionality.
On this publish, we’ll check out how the 2 cameras examine that will help you choose the proper one in your images or videography.

• Sony A7S III: 12.1Mp full-frame BSI CMOS
• Canon EOS R5: 45Mp Full-frame CMOS
Though they’re each full-frame cameras, the Sony A7S III and Canon R5 have vastly completely different pixel counts. By present requirements, a pixel rely of 12.1Mp appears very low, however crucially, that’s adequate for 4K video recording and it signifies that every of the pixels is way bigger than these on the next decision sensor. That provides the A7S III a definite benefit for low gentle taking pictures as a result of bigger pixels create a cleaner picture sign so pictures and video have much less noise.
On the flip-side, the 45Mp sensor of the Canon R5 means it captures a excessive stage of element and there are sufficient pixels to create 8K video – extra on that beneath.

• Sony A7S III: 4K at as much as 120fps, 10-bit 4:2:2 color, 16-bit uncooked video over HDMI
• Canon EOS R5: 8K at 29.97fps in 4:2:2 10-bit in Canon Log (H.265).
Make no mistake, 8K video recording eats via reminiscence card house and enhancing the footage calls for some critical processing energy, however the outcomes from the R5 are very good. Nonetheless, many individuals who presently shoot in 8K do it to allow them to create two or three completely different 4K crops from the identical clips.
The R5’s 8K functionality additionally allows HQ 4K mode during which the digital camera downscales the footage to 4K with extra element than regular – and the outcomes are gorgeous. Nonetheless, taking pictures at such excessive decision generates plenty of warmth and you’ll solely report as much as round 20 minutes of 8K or half-hour of HQ 4K earlier than the R5 must take a break to chill down.
In distinction, the Sony A7S III has a most decision of 4K, and it could possibly solely report uncooked footage to an exterior gadget just like the Atomos Nina V, however you get 16-bit uncooked recordsdata and it retains going so much longer than the R5. What’s extra, the outcomes are very good, so except you have got compelling cause to seize 8K video or HQ 4K video, the Sony digital camera is the higher choice.
3. Sensitivity vary

• Sony A7S III: Stills: ISO 80-102,400 expandable 40-409,600, Video: ISO 80-102,400 expandable ISO 40-409,600.
• Canon EOS R5: Stills: ISO 100-51,200 expandable to ISO 50-102,400, Motion pictures: ISO 100-25600, expandable to ISO ISO 51,200
As we touched on earlier, the distinction within the two digital camera’s most sensitivity (ISO) settings is defined by the distinction of their resolutions and pixel pitch.
Whereas the uppermost commonplace sensitivity (ISO) setting will be helpful now and again, we’d advocate holding the ISO setting to not less than a cease decrease on each cameras. This brings the A7S III all the way down to ISO 51,200 and the R5 to ISO 25,600.
This additional flexibility with the Sony A7S III can come in useful in low gentle situations supplied that you simply don’t want a big picture. It may, for instance, work properly for wedding ceremony photographers who wish to shoot within the low gentle of a church and seize pictures to go in an album.
• Sony A7S III: Hybrid with 759 section detection factors and 425 distinction detection factors, Actual Time Eye AF (Human and Animal for stills, Human for video)
• Canon EOS R5: Twin Pixel CMOS AF II section detection with 5940 factors in stills and 4500 factors in film mode and AF Monitoring of People, Animals (Canines, Cats and Birds) or Automobiles (Racing vehicles or Motor bikes)
The Sony A7S III’s AF system is way improved upon that of the A7S II and the Actual Time Eye AF is a significant bonus for social photographers and videographers. Nonetheless, the Canon R5’s AF system is just very good and, not like the A7S III, you get the identical performance in video mode as you do once you’re taking pictures stills, so you possibly can observe people, autos or animals simply and use Eye detection.
5. Steady taking pictures

• Sony A7S III: Mechanical and digital shutter: 10fps for as much as 1000 uncompressed uncooked recordsdata with a CFexpress card
• Canon EOS R5: Mechanical shutter: 12fps, Digital shutter: 20fps for 350 JPEGs or 180 uncooked recordsdata
Though the decrease decision of the Sony A7S III allows it to have an exceptional burst depth, its most steady taking pictures fee is definitely decrease than the Canon R5’s. It’s a advantage of the processing energy that’s required for taking pictures 8K video.
It takes 17.5 seconds to shoot 350 pictures at 20fps, whereas taking pictures 1000 pictures at 10fps takes 100 seconds. If that you must shoot for longer, it’s doable to scale back the body fee of the R5, however 17.5 seconds is a very long time to shoot stills. It’s greater than sufficient to seize all the Olympic 100m remaining, for instance.

• Sony A7S III: Twin: SD/SDHC/SDXC (UHS-II) and CFexpress Sort A
• Canon EOS R5: Twin 1x CFexpress sort B, 1x SD/SDHC/SDXC UHS-II
Each cameras have twin card slots however solely the Sony A7S III has two an identical slots. They’re additionally versatile as a result of in addition to accepting USH-I and UHS-II compliant SD/SDHC/SDXC sort media, the slots are suitable with CFexpress Sort A playing cards. These playing cards are smaller than CFexpress sort B playing cards however slightly slower.
Canon opted for an SD/SDHC/SDXC slot and a CFexpress sort B card slot. Whereas this latter card allows the quickest file switch speeds, it means that you must carry two several types of card to get most storage capability.
Sony A7S III vs Canon EOS R5: conclusions
Though the Canon EOS R5 is able to producing superb-quality video and at increased decision than most different cameras, it’s restricted by its warmth era. The Sony A7S III doesn’t have the 8K video functionality of the R5, however the high quality of its 4K video is implausible and general, the A7S III is the higher digital camera for video.
Apart from the few photographers who may profit from the flexibility to make use of very excessive sensitivity settings for capturing stills, the Canon R5 is a extra versatile and succesful stills digital camera. Its 45MP decision lets you create bigger prints and make extra dramatic crops than a 12MP picture.
Each cameras have good autofocus techniques, however the Canon R5’s has the sting over the A7S III.
How we take a look at cameras
We take a look at mirrorless and DSLR cameras each in real-world taking pictures eventualities and in rigorously managed lab situations. Our lab checks measure decision, dynamic vary and sign to noise ratio. Decision is measured utilizing ISO decision charts, dynamic vary is measured utilizing DxO Analyzer take a look at gear and DxO Analyzer can also be used for noise evaluation throughout the digital camera’s ISO vary. We use these real-world testing and lab outcomes to tell our feedback in shopping for guides. For compact cameras and telephones, we choose on actual world dealing with and photographic outcomes alone.
