Cosina f/2 50mm stuck wide open

Thedarkb · 02-03-2015, 02:44 PM

I bagged a really cheap cosina 50mm f/2 lens on ebay for my cosina CT-1A(k mount) however it's stuck wide open and was wondering how I could free it?
thanks in advance

Sounds like oil on the blades.
There are several videos on the web about taking a lens apart.
If you have never had one apart, all I can say is good luck.
