Farewell to the DSLR camera

Surely the fact that the lens can be detached from the camera body makes it somewhat straightforward to test on an optical bench?
nightfire:
Yes and no- due to the nature that some parts are present in todays lenses that were not present in the mechanical lenses we had till the 80ies, it is harder.
For example, in modern days lenses the aperture control is digitally controlled in most lenses. Nikon F Mount is one of the manufacturers that did not do this due to downwards/upwards compatibility of the whole system. But in the Z system, they are also electronically controlled.
Same goes for the VR system, that lots of lenses have.
Apart from these things, a comparison on an optical bench would be really interesting, as camera manufacturers are able to remedy in software the known kinks of their lenses to a certain degree.

WYSIWYG
As bd said, mainly exposure control....
No more bad surprises after you took the shot. Plus all the mechanical mirror system jazz circus is gone....
I am pretty much sold on the Canon R6, R5 is a nice horse but it is an expensive warm battery killer. No bueno senor.
Plus I am starting to hate the CF cards...

You rocks!

I don't think any manufacturer has been caught doing lens correction to raws yet. That's what lens reviewers use to test their "raw" (hehe) performance. With JPEGs, such tests would be screwed by many other factors too, like sharpening.
Some cheap wide angle zooms do exhibit quite a bit of barrel distortion which is corrected by the JPEG engine.
