I am having trouble distinguishing between the two sets of photos as I'm going through them. So yes, Sigma 17-50 is good. 5D3 | 24-105mm L | 85mm 1.8

pulsar123 Goldmember More info | Feb 21, 2012 14:59 | #10 From what I've seen, Sigma is comparable to Canon: slightly better in some areas (like, no zoom creep, and not a dust collector like Canon), slightly worse in other areas (like AF speed), and pretty much on par in terms of optical quality. 6D (normal), 6D (full spectrum), Tamron 24-70 f2.8 VC, 135L, 70-200 f4L, 50mm f1.8 STM, Samyang 8mm fisheye, home studio, Fast Stacker

Right now (until the end of March) Sigma has a rebate for the lens, so it only costs 594$ at major retailers (Amazon, B&H, Adorama). Go for it! I didn't find a very discernible difference between the AF of the two lenses. I did find the Sigma to have better center sharpness and the Canon to have better edge sharpness (that's wide-open to maybe two stops down). 5D MK II

From infinity to minimum (and back) the Canon is a bit faster. The advantage of ring-USM vs. micro-HSM. Also, the Canon has full-time manual focus whilst the Sigma does not.

How is the servo focusing with the Sigma 17-50? With my 30/1.4, even though the one shot focusing is dead on, it seems to update itself in servo mode less frequently than my USM lenses and as a result, I miss more shots with it. Canon 7D/350D, Σ17-50/2.8 OS, 18-55IS, 24-105/4 L IS, Σ30/1.4 EX, 50/1.8, C50/1.4, 55-250IS, 60/2.8, 70-200/4 L IS, 85/1.8, 100/2.8 IS L, 135/2 L 580EX II, 430EX II * 2, 270EX II.

I have only tried chasing my kids around in servo once a few days ago with the 17-50 and it didn't do horribly. But it didn't blow me away either. 5D3 | 24-105mm L | 85mm 1.8
