I found a canon T70 camera and it has this very strange lens. It is a
FD 35-70mm 1:4 AF lens. I can't seen to find anything about this lens other than it being canons first attempt at a auto focus lens. It has some sort of a motor driven AF system on it. This is a very large heavy lens weighing around 1 1/2 pounds! I put batteries in it and it works and seems to be in excellent shape. Is this a rare lens? Any ideas as to the value of this?
