Sigma ART lenses start to really shine honestly. Generally very well corrected optically, much less vingetting on FF than other lenses when wide open, and even slightly cheaper priced to the olympus. They are significantly bigger though (the 50mm 1.4 is 815g, versus 410g for the oly).

well, have you ever use that sigma art 50mm f1.4 before?

I’m curious about why you asked that question

Peter

well, have you tried it? how's the vingetting? of cource on the uncorrected raw... that simple

now you're asking me the question - or you've mistaken me for the OP

Are you asking to learn about the lens, or are you already familiar with it and you're trying to make some point about how poorly or otherwise it performs ? - that simple

If you really do want to learn about the lens then there are plenty of reviews out there. Here's one by Ken Rockwell Sigma 50mm Art

and this is what it says about vignetting . . .

and this from photographylife.com

Is that what you wanted to know ?
