Hi Alex, I am still using Opemus 5 with Anaret 80 lens for my medium format (Yashica TLR) occasionaly. It's fun and results are (30x40) perfect (at least for my eyes:-). I paid 15 euro for used one last year, but they were quite common here in Slovakia. Not sure about filters for IIa, but mine has filter drawer above negative holder. Now I see that meopta.com website is changed. Last year you would be able to download manual for all old products (czech or german language with pictures). Maybe you could email them...
