My wife has been appreciating the low-light, indoor capabilities of my Canon 50 1.4 so I decided its time to get her something fast for herself.
She has a Rebel XT with the kit 18-55 and a 70-200 f/4 that I "bought for her."
Since I already have the 50 and it can get a little close in cramped indoor spaces I want to get her something wider..
Without going over $500 my research is leading me towards the sigma 30 1.4, is there anything else I should be considering?
