Squinty, yes, but very clean (no framelines or meter displays). And you get used to it – I had no problem with my Zorki C's viewfinder until I got a Vitoret, which was my first 1:1 VF.

If you're in the mood to use it, it can be a great experience (rather like using a box camera) – if you're in a rush, you'll start fumbling unless you're really practised with the system.
