Picked up the GF 20-35 yesterday because I wanted something wider for a trip this summer. These are some of my "getting used to" shooting buildings wide and close at the campus of WSU-Vancouver. So far impressed. Corners seem not to have the smearing I had with the 10-24 on my X-T2. One shot looks like I have bad vignette but my magnetic filter had slipped and the bottom corners are from that.
Not meant to be anything special but haven't seen a lot of 20-35 shots so thought I would post anyway.
