>>4084722Happens randomly at all focal lengths. I tried to look for an exmaple but couldn't find any, because I usually delete all affected photos. I only use my DA18-55II in two cases:
a) I absolutely need the 18..35mm field of view,
b) close-up photos where sides/edges would be blurry anyway.
I use F35-80 F4-5.6 for everything else
