:cry:
I have XSi and got Tamron 17-50mm f/2.8 XR Di II LD Aspherical IF SP AF after reading the excellent reviews for this lens..
now after having used it for a while, i can say that i do not get really great pictures as it was supposed to produce... Not that i have not tried everything, but i tried almost all the modes... tried landscapes, silhouettes. portraits, etc...In general my opinion about the pictures is "OK".. now i m thinking was it really worth spending that much money?
I also have nifty-fifty, and I usually am more amazed by its output than that for Tamrons... I never had a kit lens so cant compare with it...

I took a chance of assuming that it is the XSi that is the issue and recently ordered T3i..I have not received it yet, but i hope that i get good sharp images with that body..

Am i forgetting something, like post processing all the pictures? Any opinions? (I expect some bashing here that People should not blame lens/gear, but themselves, but believe me, I am fair at photography and knowledge, i am really happy with 50mm f/1.8)

It would help to know EXACTLY what your issues are .. lack of sharpness, color, contrast ?

That is why i said, I took a chance of assuming that it is the body that is messing up... :( I may be wrong...

my issues, are mostly Sharpness.. I have tried kit lens (on my frnds setup), output is similar (talking about nonXSI+18-55mm)..did not see Tamron standing out... When i newly brought this lens, i did try the "focal length" test...couldn't figure out much, seemed ok... let me dig through that test results, if found i will post that too....

I am not quite happy with the sharpness...
my friend with t1i (50% sure abt model, but definitely REBEL) + 18-55mm IS II seem to have similar pictures of the same subject..
no filter.. no post processing of any sort..
