Buying a beautiful f/2.8 lens zoom is tempting. Large apertures are always better. If you’re using primes, a f/1.8 or f/1.4 is even better. But is that expensive large aperture lens really necessary for your photography?
The first lens I bought next to the one I got with my camera was the beautiful white Canon EF 70-200mm f/2.8L IS USM. Its name is a mouth full, basically meaning it has that amazing f/2.8 aperture over the complete focal range. It is white, it is large, it is heavy, it looked good on the camera, and people were impressed by this huge white expensive looking lens.
