So I'm lucky enough to be of to NYC soon and in the absence of a decent digital SLR I thought I'd dig out my dads old Zenit-E for an altogether different experience. Thing is, it's really dusty on the outside from sitting around unused. What would people recommend for cleaning it up? Some isopropyl alcohol? Also, I used to shoot with Ilford HP5 400. Will that be fast enough this time of year in the city for a little street photography or should I go for something a little quicker? (I don't mind the grain). Thirdly, if I was on the lookout for a wide angle lens for this camera, what could I go for (I'm not sure of the mount). Cheers Jon.
