Sonnar2: Mine came with the same pouch, but it seemed too big for the lens. My question about it was prompted by seeing a post from someone who bought a Hexanon-M 50/1.2 from the same source as I got my UC-Hex 35/2 -- and he complained that the seller had not included the factory lens pouch in the box. That got me thinking that, since mine was too big for my lens, maybe I'd ended up with his pouch by mistake. But it seems not. A hard case would be nice -- I've got a couple of small vintage hard cases on the way, maybe one will fit.
Peter: Yes, I got the CV 43mm hood w/cap from CameraQuest, and I use it on my UC Hexanon. Works very nicely, and is much more compact. 🙂
