I came across this website when I was loking for something not connected with photography. The lists are quite comprehensive:-
sovietcams.com
There are a lot of items I had never seen before and an explanation of some of the more common cameras we see in the west.
Yes, this is a good website.
For me the apex of the soviet cameras is the Kiev SLR line, specifically the Kiev-15 TEE.
You can call it "the russian Contarex". Looks like a real high-quality item. I wonder who in soviet russia was able to afford that machine. Or who used them.
Russia also had some special, obscure, hi-performance lenses, but those weren't mass-produced, they came straight from the GOI (the optical institute that designed the lenses). Normal, mass-production lenses were designed at the GOI and then built by the different factories like KMZ, Arsenal, LOMO, ZOMZ, etc.
