<p>Thank you for all the replies. This whole thing was sparked by a dealer here in the UK listing a near mint F1n with 55mm f1.2. GAS almost got me but common sense has kicked in. I really don't need another F1 and, already have a 1.2L and 1.4 new FD mount lenses. So I will pass on this one. </p>
<p>Thank you Jeff and Jim, I had forgotten all about the Canon Museum. The lens I am looking at can be identified as an early 71-73 f1.2 not SSC coated. So that poses more questions, any good optically and is it worth anything? </p>
<p>My question is, how many breechlock variations of the 55mm 1.2 lens are there? Looking on the Malaysia site shows only one but I think there might be more. Cheers.</p>
<p>The point made about activity on the FD forum ought to end the argument. Here's one more shot made with a FD camera for the simple reason I don't have a digital camera</p><div></div>
