EF 600mm f/5.6 IS, I'd much rather have this lens than a 500mm f/5.6 even if it's going to cost more.

EF 12mm f/1.0 IS

EF 18mm f/1.0 IS

EF 24mm f/1.0 IS

EF 35mm f/1.0 IS (Voitlander has a f/1.2)

EF 50mm f/1.0 IS

EF 85mm f/1.0 IS

EF 135mm f/1.0 IS

EF 200mm f/1.0 IS

EF 12-24mm f/1.0 IS

EF 24-85mm f/1.0 IS

EF 85-200mm f/1.0 IS

EF 300-800mm f/4 IS

EF 1200mm f/5.6 IS

Thats quite a lot of Fast Glass!

Cheers,
John.
