Hi guys, I am starting to take my photography and videography more seriously and have decided I need a new lens. I am shooting majority crop on the 600d. At the moment I have the UWA tokina 11-16mm which has worked great for all the party style photo's I want especially linked with my 430exii I have also recently upgraded from the 50mm Canon f1.8 to the f1.4 mainly so I can attach lens gears to it for my video work. I think at the moment I am missing something in the middle. I'm not really worried about getting in tighter as I find that I can use my feet and the 50mm. I have used the 24mm f1.4 before and whilst thinking at the time that it wasn't quite a WA and not really tight enough I think in retrospect I have decided that it was actually a really nice mix of widish FOV and DOF. I think a fast 24mm - 35mm ish lens would be pretty good although I haven't had extended use so I am not sure. How does something like a 24-70mm f2.8 compare to the prime lenses? Also are there any deals I should look for (i.e. is the sigma 30mm f1.4 much better than the canon 35mm or is it better value?) Any help would be great! Cheers!
