Lieca link is interesting with the sample picture.
I am actually surprise by the DOF of F/0.95 when looking at the back glass, as usually these creat a paper thin field of focus and everything else is OOF.

I heard Canon once manufactured 50mm f/0.95 lens. In the 60-s.

A few other companies dare to make that too including Zeiss.

I found this while answering another query. Looking for Leica and then a mini diversion. :rolleyes:

750 exposure film back on an F2S. Now that is BIG. :eek: :D

Don, the motocycle club I used to belong to once had a talk given to us by the Metropolitan police force section that managed the speed cameras in central London. This was mid-late 1980s, before digital cameras were common. They used an Olympus OM1 fitted with a similarly big film back. It would still run out of film in a couple of days at some of the worst blackspots.
