Comparing the Image Quality Between the Sony a1, Sony a7R IV, Canon R5, and Nikon Z 7II

The standard resolution of camera sensors has skyrocketed in the last few years, and the once niche 50-megapixel level is now very much a standard figure. This excellent video compares the image quality between four of the most respected modern cameras, the Sony a1, Sony a7R IV, Canon R5, and Nikon Z 7II.

Coming to you from Tony & Chelsea Northrup, this great video review takes a look at the image quality between the Sony a1, Sony a7R IV, Canon R5, and Nikon Z 7II. No doubt, we are spoiled nowadays. Whereas just a few years ago, very high-resolution sensors were restricted to a few niche cameras that were built for that specific purpose, now, we can have high levels of resolution and dynamic range in a body that can also fire off frames at a breakneck pace, something that was simply unheard of before. It is certainly a treat to be able to track a quickly moving subject and take a quick burst and be left with a wide range of shots to choose from with plenty of room to crop and recompose the photo after the fact. Check out the video above for the full rundown from the Northrups.

The R5 and the R6 has an (L) ISO-50 Setting. Why is this not mentioned?

Could be because it's not their base ISO.

Thats obvious sir. What is the difference in quality or performance based on using this "non base setting" vs the precious base 64 ?

From what I understand it to be, ISO 50 where the base ISO is 100, is like exposure compensation -1 stop. There's no perceivable difference performance wise. An example of a use case for using an "extended" ISO 50 is with that photo you posted below. You would have had to stop down your precious f1.2 by +1 stop without the extended ISO; or use an ND filter.

Nikon’s Z7 and Z7ii still have lower base and pushed ISOs at Lo 1 of ISO 32. A fun perk of this is being able to shoot 0.95 wide open at 1/8000 mechanical and still get properly exposed shots in daytime! Very niche, but fun.

All the cameras have an extended ISO below their base ISO, so the Z7 II would still have the advantage if we decided to use the extended ISO. Cameras achieve the extended ISO by reducing the highlight dynamic range. It's definitely OK to use the extended ISO, but to keep it fair, we stick with the base ISO recommended by the manufacturer.

Decent review. All are good cameras that enable photographers to make great images.
