Hey everyone, it has been a while since I have posted but I am having a little bit of an issue and I need some help. I bought an adapter a while back so I could use older Yashika lenses on my Rebel Xt and it worked decently well. Well, I havent used the adapter in some time and I am now shooting with a 20d. When I put the lens onto the adapter, then onto the camera I am throwing Error Code 1. I tried to not screw it on all the way so the little pin didnt make contact with the body but it still throws the same error code. Am I making a stupid small mistake or am I doing something all together wrong? Any ideas? Thank you to everyone in advance!!
