OP, do you usually under expose your photos? Did you use any post processing software?
I actually think this is part of the problem. Im not very good with light settings and ive been so used to using a stock lens that lighting has always been a struggle for me. I dont have a 1080p res laptop but even with my 720p screen, i can still see noise present in multiple photos. most of the noise is after editing as far as i can see, but I HAVE to edit, but i have a hard time editing without getting noise. On another note, Ive been taking a look at the 7D and i do like it. the 6D and 5D MkII seem like great cameras but are super expensive (on amazon at least.)
