Okay, one of my mates' sons has asked me about a good wide angle for his just bought 7D. He's gone out and bought the camera and a Sigma 24-70 F2.8, but wants a wide to go with it, initially for travel. I've suggested three lenses for him as he wants to turn this into a serious hobby and the little bugger has more funds than I do.
My suggestions were:
Tokina 11-16
Sigma 8-16
Canon 8-15 F4L
I've seen plenty of reviews on these, but does anyone have any real world experience with the last two?
Cheers,
