Hi! New to talkphotography - great site - and new to DSLR. I've just bought a Canon 400D and have been given a 20 odd year old tamron adaptall 2 80-210mm lens. I'd like to try to use the lens but my local camera shop said it would not be a good idea. Looking on ebay I see there are some mounts available, mostly from Hong Kong, or others custom made. Has anyone any advice on this topic?
