Well if you don't use a brickwall or newspaper, focussing shouldn't be a problem as you would look at a shot for the sharpest part and blow up that.

Anyway thanks all, but no one seems to know whether an excellent 35mm lens is limited for it's full potential, using 200asa film.
It depends on the lens and the film.
Good films resolve (actually, not theoretically) about 100 to 160 lp/mm. The best films did about 200 lp/mm.
A 200 ISO film can be good, can be less good.
Is it true that 200 ISO neg film is just 100 film and the labs push it, and if it is could I get a consumer lab to push a film by a stop just by sticking a 200 DX code on it?

The thread can be summed up:- If you want to check a lens out, then select a slow film colour or B/W, use a heavy tripod, set lens at about f8, choose a subject that can show sharpness, check exposure is correct, have a lab develope and drum scan the neg.....phew

Only if you ask for a push or pull will they need to process differently.
