I'd really like to purchase an UWA lens that is also very capable at low light for indoor shots, without flash. So far, my research has led me to the Sigma 20mm/f1.8, which is priced at just under $500.
Anyone else have recommendations for a decent wide and fast lens for my XSi? It appears that because I'm looking for something with a high aperture, I'm limited to primes, which I don't mind at all.
Thanks!
