I am planning a few days in Paris mainly for photography, and am considering getting the EF 50mm f1.8 mk2 specificaly for this trip to use in Low light conditions, early mornings and evenings. However iv heard this Lens struggles a bit focusing in low light, and I know the manual focus ring on these plastic Lenses are flimsy and not very responsive. Which sort of defeats the object of using it in Low light. I used to have the mk 1 version, along with some other primes, but ended up selling them as they never got much use, much prefering to use my zooms. This Lens would not get much use, which is why im going for the mk 2, (also the mk 1 is becoming harder to source now) im just a bit concerned about its focusing ability in low light, and am curious to ask other users of this Lens their experiences of using it in Low light, specificaly on focusing. I know its a good Lens opticaly. Much obliged, Tim.
