Lille, today.
Zf, Canon 85/1.8 FD wide open. That lens is very homogeneously sharp but, at full aperture, sports some pink fringing and a (sometimes) endearing "glow". Of course that's an old lens, bought 2nd hand about 40 years ago, so the coatings etc. can't compete with those of recent lenses. In particular, mounted on m43, the Olympus 75/1.8 is clearly superior in all respects. Still, that old-timer is usable on full frame, and probably at least as good as its Nikon sibling that did not satisfy at full aperture (unfortunately, I cannot make any direct comparison, having sold it).
