"don't make"? I need a 28mm f1 for environmental portraits...

The optical performance may not be the same, the Nikon version may have been modified for the thicker stack on top of the sensor...

It would have been even more difficult to match Sony's 50mm f1.2 GM, the best 50mm f1.2 lens around and with four linear XD motors, two moving groups...

@whawha You can still buy these lenses and adapt them on your mirrorless camera... You can can many 50mm f1.4 for $150 and an f1.2 for $350...

...and this new Sigma 50mm f1.4 weights 140 gr less than their previous 50mm f1.4 Art...

Or in three years the A7R VI...

@hjs_koeln SNR between sensors with different resolution must never be compared at pixel level...

@Rob Yes same sensor, but the better AF and better Viewfinder may help to get a better framed and better focused image on that same sensor...

:D

Same sensor, same noise... You're an id**t only for doubting so much... Get the a7RV and enjoy the improvements, e.g. the larger viewfinder, better AF...

@content_creator I get your point and the Sony camera for you is the A1, not the A7R V...

I have a Fujifilm GFX 100S and a Sony A7R IV, and there are quite a lot things the A7R IV does better...

Medium Format is better...

They should look into a technology called IBIS...

@gameshoes Yes, being mirrorless, better lenses can be developed... The D850 also lacks IBIS, eye AF, magnification in the viewfinder to focus manual lenses, ...

The camera producers test that will all lenses, and then publish the best performance obtained...

No shame at all, it is a "stills" oriented camera... Shame on the other brands, as they are not able to have any comparable camera for stills....

A longer lens won't give more background blur, you only will see a smaller part of the background... "Portrait"doesn't mean only headshot, you also have "environmental portraits" and for that my...

"best stills/video"camera doesn't mean the same as "best camera"... and the "stills" performance of the A7R V is soo much better than the R5 with an inferior sensor...

The Z7 II is much better than the D850

@Mateus You shoot landscape at ISO 1600 ?
