Tamron Vs Sigma (Kit replacement) f 2.8 comparison

Hi Guys,

After running about for close to a year with the DA-L 18-55 kit... I've found that I'm really needing a faster lens for indoor shoots in church and also some outdoor night shoots. Tried out a friend's DA* 16-50 and how I wish I could just afford to buy that right now!!

The go-to lens that everyone recommends seems to be the Tamron 17-50 f2.8 which is an awesome lens at a fairly decent price. However, the Sigma is what's intriguing me. The Sigma 17-50 looks good, but is really large and is creeping into DA* price range and I'd rather get the 16-50 if I could afford it.

Does anyone have any hands-on, real world feedback on the pro/cons of the Tammy 17-50 versus the now-discontinued Sigma 18-50 Macro f2.8s in terms of Sharpness, AF and other tangible factors or can point me towards some decent head-to-head comparions would be awesome!

I had the Sigma 18-50 f/2.8 macro for a little while and I really liked it. Sharpness was great wide open and AF was decently quick, if a bit noisy. The close focusing abilities made it a good all around lens. Here's some stuff I've shot with it.

Thanks William, I'll check it out.. have you ever tested out the Tammy 17-50 before?

I wondering besides the larger front element 72mm Vs 67mm for the Tamron, and slightly heftier dimensions of the sigma.. is there anything that would tip things back to the sigma despite its slightly higher price as compared to the Tamron
