Count me as one interested in Z7 vs GFX 50S/50R  system IQ comparisons.

Aren't those the same people who've abhorred "clinically" sharp lenses (and consider SA a feature of "character")? The move to a Z seems like the wrong direction for them.

I'm surprised that's not the plan. Hollywood does like to tell us about his purchasing habits.

No inside information from your Nikon "source"?

Sigma is using cheaper glass types. Which means element size and count goes up to get same performance versus more exotic glass composition in other lenses. Hence how they can undercut their...

Have you (or anyone else) used the 55 reverse mounted with/without another lens? Curious what kind of setup could be achieved if used in combination, for example, with the 135 or a macro lens in ...

I'm certain I've come across one of Roger's blog posts discussing how he has to approach the Japanese companies in a manner that allows them to save face without impacting the working relationship. ...

Three weeks later and compatibility list isn't updated.

Did the electronic rangefinder still work? The lens compatibility information I've read makes it seem that aperture can still be set/controlled by the body, but ERF functionality is lost. Granted ...

So many people want 15 minutes of internet forum fame for being the first to post some article about the latest gear regardless of the quality of the material.

The first graph is fine when comparing sensors of same format and resolution. Bill's PDR chart is better still since he accounts for format and resolution along with the noise characteristics.

Input-referred read noise is a better comparison ( link )
