Originally posted by stormdore Yes - I have the 18-55 mm lens. I don't know what I have to do to "master" the lens. I mean, the pictures I take are actually pretty good.

I guess I'm not sure what the "mm" difference is (10-17 mm vs. 18-55, etc.), nor am I familiar with what the "f" is for (with the exception that it would be similar to the "f stop," but still not 100% on that one.
If anyone knows of a website that might be able to explain this info, I would be soooooo appreciative!

Hi Terri and welcome to the forum. I don't really know of a website that shows the same scene shot with different focal lengths but maybe someone else knows one. If not, I'd go to pbase and do a search for different mm lenses. That way you can see the different pictures taken with the different lenses. I'd stay with primes, since they have only the single focal length it's easier to see what that particular length is capapble of. To start off try looking for 14mm shots; 24mm shots; 35mm shots; 50mm shots; 70mm shots 105mm shots etc. as you get higher in the mm range you can take bigger jumps.
(I don't know how experienced you are, a "prime" is a non-zoom lens, if you knew that I didn't mean to offend)
The "f" does stand for f-stop. On a lens usually the fastest f-stop is listed. If it's a zoom and a range of f-stops is listed (for instance the DA 18-55/ F3.5-5.6) that means that the fastest aperture gets larger as the lens is zoomed out. In the above mentioned lens, that means that the fastest aperture at 18mm is f3.5 and the fastest aperture at 55mm is f5.6.
