Confusion and Suggestions for Wide Angle

[sirhc_1]

I would try to recommend the Tokina 11-16 2.8 (for crop body) like the 40D. Its sharp & fast. Great for wide angles in low light. You might want to try the Sigma 10mm 2.8 fisheye.Like the above mentioned, its sharp & great in low light shooting as well. If you like exaggerated distortion, this is your tool. You can "de-fish" it with PTLens.

If you're happy with the 24-105mm f/4L as a 'walkaround' (general purpose) lens, then I'd recommend the EF-S 10-22mm f/3.5-4.5. If you want a wider angle and a faster aperture for indoor shots, then get the EF-S 17-55mm f/2.8.
