Lower fstop numbers = a larger aperture (lens opening )= more light coming in = faster shutter speeds = better An f4.5 lens is considered relatively slow. The fastest zooms are usually around f2.8. Some lenses are more expensive but look at the Tamron 17-50 or Tamron 28-75 f2.8s. Well priced and sharp.
Prime lenses (fixed focal length lenses) are usually faster. Check out the 50mm f1.8 (very sharp and fast). Great for lower light photography.
If you don't know what aperture is, you really should not be shooting a wedding. Buy "Understanding Exposure" by Bryan Petersen.
Ugh. I completely understand what aperature is... I've helped others on this FORUM with it, and read alot about it. However I really don't appreciate your judgement on what I should or should NOT be shooting.
My confusion came with the stock lenses and their LOWER aperature at higher zoom, I had forgotten the number AFTER f/3.5.
Thanks for assuming though.
