Ok so this is probably just a n00b question, but I'm a little discouraged.
This weekend I shot in an indoor paintball facility where the lighting was much less than optimal, which required me to use a very high ISO (6400 to be exact). Now I understand that higher ISO's create more digital noise in the pictures and what not, but what I'm bothered about is that several of the pictures are useless because of that noise.
So, I'm curious, would a better lens help with that, or is it completely a limitation of using a high ISO?:o
