Been thinking of starting to use my 1d3 for my RE photogrpahy(been using my 50D with Tokina 11-16). Part of the reason I am thinking of this is because, while I love the Tokina, the sun flare (or light flare) can be extremely irritating. I also am looking to use the 1d body (which can't take the Tokina without modifications) so I need to get a wide angle lens for the 1d. I'd love to get the 16-25 but don't want to spend quite that much at the moment. Been looking at the 17-40 and like what I've seen/read.
Anyway, my main concern is flare with the 17-40. I don't expect it to be totally eliminated but have any of you experienced any major issues with flare using the 17-40?
