Being that I am a college student starting out my photography business I do not have a huge amount of money for purchasing a variety of lenses, so I was deeply considering getting the Sigma 24-70 lens, which is inexpensive enough to allow me to purchase another nice lens. If the Sigma operates very poorly in low light, I may just wait to purchase the Canon 24-70 as well as other lenses. Question for Thomas Sullivan and Collin Carron because you both owned the lenses I am currently looking to buy. What do you think about the low light performance? Will it produce only poor photos or would they only be slightly less quality in low light situations with the Sigma 24-70 as opposed to the Canon 24-70? Thanks a lot guys!
