Hi all, i'm looking for a good prime lens for my entry level Nikon DSLR. I'm still newbie here so it must be an all-rounder prime lens. Been searching in other forum, and i'm interested in that 50mm lens. But still confused about 1.4 vs 1.8 things, whats the difference between 1.4 and 1.8? Which is better? And should it be MF or AF? Regards.
