But I'd like to see an optical comparison before weighing in on that part. Unfortunately I don't have the FE 90.



Fortunately the 90mm is well documented by various reviewers. I'll point to just two reviews as they have easy-to-replicate-at-home tests:

Dustin Abbott:

The "counterlit morning dew in the grass" pic is easy to take and compare. If one doesn't have grass at this time of the year, I've provided one with the Sigma earlier in this thread. The Sony shows "onion rings" and very rough polishing of one or more elements. Dustin uses to take that pic for many lenses so you can compare with more than the Sigma.

Dustin also has a review where he directly compares the sharpness of the two lenses:

and the Sony is not the winner.

Ken Rockwell:

Ken frequently uses a picture of a wristwatch to document CA. This is easy to replicate at home and also to compare with his reviews of other lenses. The CA there is quite visible.

Strictly from an optical pov, I would say that it is the Sigma that is the most accomplished of these two lenses.
