I have started two user Ipernity groups for Yashica and Takumar on the community (Ipernity reminds of Flickr, bur a little bit different and for more documenttypes). I see it mostly as another place to meet people who like this old crap lenses ;) Building the network… But I also got the feeling that Ipernity is more for serious discussions, Flickrs has become a bit of fishing for awards and nice comments and almost noone writes critique. Anyway, welcome to join the groups at Ipernity!:
The Takumar-group and the Yashica-group.
