Is there such a thing as medium format fast glass, ie f1.4 primes?
If not, why?
I assume it's due to size, weight and cost considerations.
Here is a summary of MF lenses at f2.8 or faster
. I'm making this up as I go along so don't rely on it 100%.
The Contax 645: 80mm f2, 45mm f2.8, 140mm f2.8
Bronica ETR (645) has a 50mm f2.8, 60mm f2.8, 75mm f2.8.
Bronica SQ series (6x6): 80mm f2.8
Hasselblad V: f/2.8 80 mm 'C' lens. The rest of the C series is slower. The F lenses were faster: f/2 110 mm, f/2.8 50 mm, f/2.8 80 mm and f/2.8 150 mm
