    Ok, I know a lot about lenses and how they work... etc...

    But I am just trying to figure out what they mean when someone says "I have one of the fastest lenses" or "This is a really fast lense"
    do they mean the aperature opens very large? Are they talking about how fast it opens and closes(time wise)? Where are the specs for the Canon lenses if it is how fast they actually open so I can know which are the best lenses...

    Thanks in advance!

    When someone says they have a fast lense it means that it has a large aperture. So you can take photos at a 'fast' speed and don't have to worry about blurring when you use it in dark lighting.

    Ok, so an aperature of 1.4 would be considered fast.... got it.
    That's what I thought... but I wanted to make sure. :)

    1.4 ( and 1.8 ) would be considered very fast I think :p 2.8 is fast, for most lenses.

    Fast lenses are also know to drain wallets/purses fast.

    I paid $65US for a Minolta SRT-101 with a 55mm f/1.7 on it. There are deals out there. Most manual lenses are going cheap. Price an AF ED 300mm Nikkor f/2.8.
