a: It won't work properly on most Canons without modification
b: I haven't been able to test it properly because of (a)
c: I've spelled this out in considerable detail and
d: I'm not offering any warranty because of a-c
I can only assume that somewhere out there is at least one person with a REALLY early Eos camera, and/or someone who modifies these lenses for compatibility with modern bodies.
later - final price was £62 + P&P!
Reminds me to ask - prior to going digital, did Canon have any Eos body equivalent to the old F1, e.g. with interchangeable viewfinders? I really can't remember one, which seems a little odd.
