A question tangentially related to this thread. What is the "fastest" lens out there? Say, is there an f1 or f0.5 lens useful for low light situations as encountered by the OP in this thread? Is such a thing possible, physically what would it look like??? The fastest i have personally seen is a 50mm f1.4 prime. Thanks
f/1.2 50mm or 55mm lenses are not unusual. Canon used to make a f/1 50mm. And I know there was one f/0.7 Cine lens made for Stanley Kubrick. There have probably been a few f/0.9 lenses in production. But for most of us look to f/1.2 or f/1.4. Personally I own F 1.4, 1.7, 1.8, 2.0 50mm/55mm fast primes lenses.
