Ron, your ZM21 shots on the a7 do indeed look terrible: I feel like there must have been something off with the camera or adapter. But when I look at this shot at 1:1:

It\'s not far off to me from the ZM21 f8 shot in your M9 21mm shootout (the one of the cityscape at infinity). Neither one has perfect corners at f8, but both seem pretty decent, and I suspect if I downrezzed the a7 shot to 18MP, the results would be awfully close (setting aside the color cast and vignetting, which doesn\'t bother me).


Looking at the A7r shots, what do you think?

To my eye when the huge size is factored in, the same could be true.

I was pretty flabbergasted when Ron\'s test shots were taken here as the gold standard, and now zhang\'s shots are \"proof\" that RF wides are \"useless\" on the the A7r.

I really don\'t get the rush to declare death.

We need to see the various downsizes and and corrected images from a variety of careful shooters.

It will be quite some time for that.
