So, I am going to buy my first DSLR soon, a Canon 7d. I am really familiar with how the cameras work in a videography aspect of it, but I have a couple questions photography wise and involving lenses.
-What are apature (spelling?) and ISO, and how do they affect your photo/video?
-Does the stock lens for the Canon 7d (18mm-135mm)come with an image stabilizer?
-What does f/3.5-5.6 IS mean?
-And for videography, what lenses could you recommend to me under 500 dollars?
