I'm looking for an extreme yet low-light capable wide angle lens for the 5D. I'm thinking about the 15mm fisheye, and just defishing it with software, but how practical is this? It'll be used for group shots, landscapes, or just whenever my 24-70L isn't wide enough. If anyone can provide some examples with people in them, as well as landscapes defished with software using the canon 15mm fisheye id greatly appriciate it.
