I've been wondering. My collection of compact F's; FM2n, FE2, FM3A and FA requires some reflection.
I've decided the FA with the 2.0/35 Ai-S and Tri-X is the perfect walkabout film slr combo. It can take a few knocks.
That's interesting, right now I have with me an F, 35/2.0 NIkkor-O, and some Tri-X, setting exposure with a LunaSix. It's been my out & about street combo for a few years. I keep it far away from knocks, though.
