Just got my first SLR cam today...the 400D... with a 50mm prime lens. I also wanted to get the Tamron 17-50mm f2.8 as I heard that this is a very good lens but unforunately almost the whole Singapore no stock (those with stock are selling very x). While waiting for the lens, I came across the Canon 17-85mm f4-5.6 IS USM which cost ard $900+. Need some expert advise here...which is better?
I found it very interesting, both Tamron f2.8 and Canon IS is actually to improve the low light condition (hope i'm not getting it wrong...as I'm a new baby for SLR cam..paiseh.. ), so which can give me a better IQ? Lower aperture value is better or with IS is better (not forgetting it also cover till 85mm)?
Your advise is much appericated.
