A trio of pancakes:
DA40xs on the ZX-L. It's meant as an APS-only lens, but it works really well on full frame, especially the ZX generation of bodies.
Chinon 45mm f2.8 on the MX. Not the best lens ever made optically (the DA40 kills it), but it's decent and suits the MX.
Yes, that is a hair band filling in as a focus ring and dinosaur stickers on the flash. Don't judge
Industar 50-2 on the S1a. This one is new to me, a 1986 model, so probably 20 years newer than the camera it is on, just arrived from Ukraine in apparently very good shape.
The FP4 in the camera now will tell me how good it is, but it's already proved itself to be... "interesting" ergonomically...
