I use a Schneider 65mm f8 but the f5.6 has better coverage, but given a choice I'd now buy the65mm f4.5 Grandagon , the MC on the Rodenstock lenses is superb.
The pre-Multi coating Super Angulons are actually well coated, and I use a 75mm f8 on my 6x17 camera and it has no tendency to flare at all even when shooting into harsh sunlight, and my 65mm and 165mm (in my 10x8) are equally as good.
I may well get another 75mm purely because coverage is better than the 65mm and it's slightly more versatile.
