I know it's hard to believe but I finally made my mind up on which all around lens to buy. I can now stop my obsession with ? vs. ?.
First thing I noticed was how solid and sturdy it feels. It's much heavier than my 50 1.8 that's for sure. I'll have to order the POTN strap. The Canon XTi strap won't do.
This lens focuses very fast in low light. I've read about a so called "noise". If this is noisy then I'd like to hear what a silent lens sounds like. If "noise" is a concern let me say that it shouldn't be in my opinion. This lens makes no more noise than my USM Canon kit lens.
It's pooring down rain here in Seattle. Hardly a great day to test out the lens. Maybe tomorrow or Wednesday. I'll post pics when I do. I want to do a side by side comparison on a tripod against my nice copy of a 50 1.8. If it's near that I'll be very happy.
I nearly went with the Tamron 18-50 2.8
The reason I did NOT buy the Tamron was...
$100 more
20mm less in range
optical tests on multiple sites - slightly less sharp than the Sigma.
curvature problem on the Tamron which doesn't exist on the Sigma.
Build quality - The Sigma feels more solid, but heavy.
The only time I'll really need the 2.8 is WA, indoors. The Sigma has that.
I hope this helps anyone on the fence. I strongly suggest that you spend alot of time researching. I was surprised at the detail of information and comparison tests online.
