With my Sigma Art 50 and 85mm lenses with Nikon mount and Commlite adapter for my Sony A7Riii, AF is good and fast, Eye AF great... My Nikon 70-200 f/4 does not work so well with the adapter

A personal observation: Only women film "vertically"... (probably more pragmatic, as men will consider this incorrect)...

Yes, and they did well... It will be will more painful for Nikon and Canon...

Good explanation

@Nixyz interesting, but I doubt they will once sell a camera with that sensor :(

@luke... Absolutely true... However, many advantages have nothing to do with the reduction of the flange...

44.44%

A better DR can sometimes save a photo taken with imperfect settings, or is a great advantage for landscape... But as you write, the advantage is true only at low ISO settings... In my case I try...

Will you rather buy a 5DSR with bad dynamic range, or a 5D mk IV that has a less bad DR, but much lower resolution?

Instead of two bad choices, choose rather the Nikon D850 that has high...

@PWPhotography... Optical quality makes the difference... Try to shoot wide open (f/1.4) and compare the sharpness between Sigma and Samyang (or other brands)...

The Sigma Art primes are...

Canon sensors are the worst of the whole camera industry...

To have smaller and lighter lenses, you need a smaller sensor... Nobody wants a smaller sensor...
And a light camera with a heavy lens will always be lighter than a heavy camera with the same...

Well, I am not an optical engineer, but this was stated by Sigma... I also noted that for many of my DSLR lenses, the design is not trying to have optical elements very close to the sensor... The...

There is no reason why the lenses should be smaller, as for lenses longer than 35mm the optical design will be the same... If the optical design is the same, than it's logical to add to the E-mount...

@mjoshi You should take into account that the design of lenses longer than 35mm will be the same for a DSLR and for a mirrorless camera... Sigma did not "slap an MC-11 adapter", but sure the aspect...

For sure the lens will not be shorter than with the MC11 adapter, but will be lighter... Adapters are somewhat heavy...

Thinks do not work the same... For example, with my Commlite Nikon F to Sony E adapter, AF in video mode is simply not working...

"Sony is who manufactures Fujifilm’s APS-C X-Trans sensors. They are actually ordinary sensors found in a number of different cameras by Sony, Nikon and Pentax. What’s different is the color filter...

The Fuji X-trans sensors are produced by Sony, therefore they are good, DR similar to Nikon/Sony/Pentax cameras, much better than Canon cameras...

This is becoming emotional... and applies to cars (their engine) and cameras (their sensor)...

Some suppliers are specialized and DESIGN the components, for example a company like Brembo (http://www.brembo.com/en)... They produce brakes...
