Soooo, I was talking to a guy in a camera store the other day about a possible Canon 24-105 f/4L purchase and he said the Sigma Art 24-105 is sharper, faster and cheaper.

Anyone on here got any real world experience with one? Read a heap of reviews online, but can't decide between the two, also never know if the staff in the store are getting told to push Sigmas for a bonus for the month. I used to work in retail and know what goes on at times.

Also happy to hear other recommendations, not looking to save the $$$ to compromise IQ, would rather just get the best I can at the moment.

Going to be a general/walk around lens.

Any advice is appreciated.
