Sooooo... I've gone out, an purchased some nice used zoom lenses, because they were convenient and fairly affordable. They work. I've got the 17-40L and the 70-200 F4 L. I've been using them for a couple of years. However I find that I LOVE my 50 1.8 because of it's smaller size and is so less noticeable, and I don't mind zooming with my feet. However, I've been reluctant to pick up other prime lenses because I feel like they are covered by my zooms. I guess I am probably most tempted by the 85 1.8, I do senior portraits for fun, and it sounds like it would be a great lens for it. But can I really justify using the 85 1.8 when I have the 70-200 F4? At some points I've thought of ditching the zooms all together to help fund a couple of primes in their place. Opinions?
