I have a Konica Minolta A2 that I got from the photographer of my wedding. It came all together and was barely used, well I have had no real need to mess with it. I just got a new lens today and I swear I am not stupid but I cannot get the lens off. There is no instructions and I do not know how to get it off. I have instructions on how to get my new one on and off but it says to use the lens release button but I am not sure where that is. I swear, I really am not this stupid. I feel like a complete idiot for having to ask this. I just got this camera a couple months ago. Any help?
