I only took 157 shots with it over the weekend I had it, and there were no controlled or optimal shots - for the most part it was candid snapshots or just shots around the house to see what the scene looked like when shot by the lens/camera. I don't have a big enough set of shots to speak to corner performance or anything like that, because typically the corner/edge areas were not in the plane of focus, and at 90mm-e that shouldn't be a big issue. I didn't find anything technically that made any images objectionable.
But having said that, my first thought is, I really enjoyed it. It was a fun lens to use. Quite easy to focus. My second thought was, it has a hell of a throw for focus by wire. I am used to the 85L, so getting used to the implementation in the sony is still taking me some time, and I still miss shots because I am turning the lens barrel so much.
I've seen reviews that say this lens isn't so sharp wide open, which imho is crazy talk. It is extremely sharp wide open.
A smugmug-resized version of a 100% detail crop:
The thing I would add that I haven't seen anyone else mention is that the lens surprised me in it's ability to render the space of a scene. Fundamentally I am talking about depth/dimension, but I have an idea what will happen
if I put a number in front of the letter d and say this lens has it. Nonetheless, besides the sharpness, the thing about the images that jumped out at me was this depth. If not strictly aesthetically, the effect is very similar in kind to the sigma 50 in it's ability to render a scene almost cinematically.
Prolly not so illustrative:
So I am really looking forward to buying one. I meant alternative to the 85L strictly as a very pleasing portrait lens, and I think it is that, and really enjoyed it for everything else too.
I wonder if there is any chance Sigma will make a 135mm-e lens along the lines of 1.8-2.0 - man I'd snap that one up too.
These examples have no PP other than resizing w/bicubic sharpening, so take them with a grain of salt as illustrative of my subjective thoughts, but maybe they help.
Given what most people consider the greatest advantages of the 85L, that would seem to be a fairly tall order for an f/2.8 lens.
No experience, but I'll be interested to read your thoughts on it.
