Mounted my Sigma 10-20mm F4-5.6 EX DC HSM lens onto my 550D (T2i) and went to Seattle. Song: soundcloud.com The T2i produces the same video as the T3i. (and similar video and FOV with this lens on the 7D, Ti1, 50D, 60D, and various Nikons and other cameras with 1.5x & 1.6x crop factors. This lens will vignette on a 5D)
