I have a canon 350d with efs 18-55mm and 17-40mm lens and im looking to buy another lens soon.
I was looking for tip on what one to buy, i want something different from theses two.I would be using it to shot almost everything indoors and out doors.Any sujestions?

got any ultra fast prime lenses? The 50mm f/1.8 or something like that goes nicely indoors. Other than that it helps to know what you are shooting. Still life, macro, landscapes, portraits etc.

Thoses are the only two lens i have and i would be mostly shooting landscapes.
