^ personal pref. I have the Canon equivalent, and I only use it outdoors, as it's a bit long indoors (with my 50D- recall x1.6 factor). If I know I'll have a lot of room to move around, then I'll use it because it's a good performing lens for the price. It's definitely a fun lens to use, but if you haven't shot primes before it takes a bit of learning to see how far you need to be for a shot.
An aside- I didn't want to start a new thread. But does anyone know of another reputable online store that sells filters like maxsaver? They're completely out and backordered of a filter I want (Hoya Pro1 Digital Protector 77mm), and I'd like to have one before Christmas. Thanks in advanced!
