Certain CSer choose Sigma 50f1.4 over EF50f1.4, for the price.
You may check Sigma sub forum, a thread discussed about this lens

Thanks! Much appreciated.
I think getting the 17-40L is big mistake if thats your only lens. You are wasting the 7ds good high iso performance if you are downgrading to a slower lens. Youll end up with the same lowlight ability as your old camera body.
If possible sell the tammy and get a 17-55. You get IS. And the USM auto focus. On a tripod yes, there may not be much difference in quality. But in the real world , the fast USM focus and the IS will allow you to maximize your 7ds potential.
The 7d seems to have AF issues so why bog it down with tammys mediocre AF.
Also, 7d has high pixel density. Camera shake will affect it more than low megapixel cam bodies. Youll need more than the usual shutter speed to focal length rule of thumb to get sharp photos. IS will help there.
Ive been thinking about this and this may have been the cause of my problems with the 7d whenever i use telephoto range.
Btw, I'm not trashing the tamron, I do thinks it s great value (especially the VC version) its just that youve already spent a lot for the best APC camera body, so might as well get the best standard zoom for it.
A 50D with a 17-55 IS can equal or out perform a 7D with a 17-50 non-VC Tamron in low light. It will also definitely do better than a 7D with a 17-40 at night.
Im facing the same situation now when I switched from 7d to 5d2. Ive got a 5D2 that has better iso capability than a 7D but then I'm using a 24-105 F4. So the iso advantage is sort of canceled out compared to a 7D with a 2.8 zoom (but not totally coz with both apertures at F4, then 5d2 has still better low light cap).
I've replaced it with a a 24-70 (on its way) 2.8L so i can regain back that advantage. However, I lose IS.
So do yourself a favor and get a 7D with the 17-55 2.8 IS (or at least a tammy 17-50 2.8 VC). Its the one thing that 5d2 owners cannot have
(aside from an affordable 30 1.4 with stunning bokeh )

I heard a lot about this lens but wide open at my 7D picture was not very sharp. At the end i sold 1 month lens for 150 lose.
Dun waste time.
sell the Tammy and get the 17-55IS. The difference is only a couple of hundeds dollars if you buy a used 17-55IS.
Else you will never "kill the cat" and it will keep on bugging you.
Not convinced? Just go buy a used 17-55IS first and try. Compare them and sell the one you less prefer. Simple.

TS has not understood that Quality and Cheap are mutually exclusive. May be better that don't waste time on him. He wants a lens that has weather seal, fast AF, good image quality, big aperture and below $1K.:bsmilie:

Guess TS ask for 50 f1.4
Yup, after some consideration, I have decided to keep my Tammy and go for Sigma 50mm f1.4. It fits my budget and my requirements as best as it could be. Weather-seal will have to be abandoned for now. Thanks for all your comments. I'm closing the thread now. Much appreciation goes to all fellow CSers.

My bro in law owns both the 17-55 IS and the 50f1.4. I have tested both the Canon 17-55 IS and Canon 50 f1.4 last night, in low light condition at a party, handheld (which is often the situation). 17-55 IS is better marginally, but just not enough for me to pay 2 times (2nd hand) or 3 times (new) more. I am sticking with my Tammy without VC/IS for now. My bro has the VC version, and again, also marginally better. Maybe I got a really good copy of Tammy which I am not disappointed. I have "killed the cat"!
I think I am venturing into primes for a change. The Canon 50 f1.4 is only sharp from f2 or f2.8 and above, like many have testified. I saw samples of Sigma 50 mm f1.4 and I am very pleased. May need calibration, but I think it is worth every penny of it. Got a friend going to HK next week, so should get a good price for it.
