Just digging out some old memories. Here is a pictorial history of the (stylistic) development from Canon FD to EOS-mount cameras First, the old standard - cameras in the wake of the "original style" Pentacon era - The FD-mount The Canon AE1-P Canon challenges Nikon The flagship of the Canon A line - making everything a little more automatic The Canon A-1 Still very much in the Pentacon mode, but getting more and more functions - And still more - the first of the Canon T-series Canon T-50 Practically all you need to do is push the button. Beginning to show the same kind of styling as the Triumph TR-3 sports car Focus confirmation appears Canon AL-1 It did work, even pretty well. But the T-series makes the first Canon autofocus camera. Combination of AL-1 focus and T style Note that the lens bulges are the in-lens focus motor But a German named Colani pummels the form - a prototype style exercise Which results in the ultimate (stylistically speaking) gem of the FD-mount line Ta-Da- the T90 - basically an EOS camera without AF Take the works of the T90, add a more compact in-lens focus motor, revert temporatily to a more "TR-3" style, and you have the first EOS camera, the EOS 650 a whole new mount, with many FD-mount users switching to Nikon F. From now, it seems like it may have been a smart move.
