Of course they test them in a rather sterile environment, which is not how I use them. Studio shooters and to some extent landscape shooters should find great value in DxO testing. Less so for sports, event and street shooters where focus acquisition is a much larger factor. But in identifying a lens for your body, DxO can be very helpful within limitations.

Just remember Bill-de the Japanese market sells less than 1/10 of all the mirrorless and interchangeable lens cameras sold in the world. And Japanese home sales trends don't always reflect the world marketplace. CIPA numbers for September: ILC sales in Japan 85,000.; rest of the world 885,000. And the month that a new camera arrives the sales figures take another swing. In the mirrorless field we are still awaiting new FF entries from Panasonic, and new APS-C and FF entries from Sony, including two rumored 8k capable cameras from Sony. Cheers

First, a disclaimer........I am not a current or even past Nikon user !

I was in Barnes a Noble Sat. - one of the british photo mags had tested the Z7 with the new 24-70 and 35mm S lenses. The Imatest numbers were the highest I have seen ! - verifying that the new larger lens mount and shorter back focus has liberated Nikon lens designers - as I predicted it would - and resulting in full frame resolution performance for lenses 50mm and shorter that we have never seen before ! The down side to this is the vignetting will increase due to physics of the lens being closer to the sensor - but this is correctable in software.

I am sure a similar advantage - at least the shorter back focus part - will also benefit the new Canon mirrorless lenses. Canon had enlarged their DSLR lens mount long ago and their mirrorless mount is basicly the same size now ......and poor Sony missed the boat long ago with their small e-mount !
