Yup, upgrading from my Nikon 18-105mm f3.5-5.6 to something better!
But is this a good choice?
Any Sigma 17-70mm f2.8-4 Contemporary users?

I'm using this for the past 4 years...
Still going strong, no focus issue...
Bought it from ebay due to couldn't find model for sony in msia long time ago...

Woah 4 years? Ain't that the previous version of it?
This Contemporary lens was released around 2-3 years ago.

But still, how would you describe the overall image quality as compared with other lens?
Example the Tamron 17-50mm VC/Non VC, or any other similar lenses?

Mine like below
http://www.ebay.com/itm/Sigma-17-70mm-f-2-...=item4d152e051e

Tamron is a bit cooler , sigma is a bit warmer...
Never use Tamron before although Tamron offer fix f/2.8 all the way

This Sigma lens needs at least f/3.5 to get sharper images

BTW, what is contemporary lens ?

Sigma has redesigned the 17-70mm 3 times, and the Contemporary version is the forth, if I'm not mistaken.

It's a part of how Sigma categorize their recent lenses, like the Art lenses like the 18-35mm F1.8 DC HSM and the Sport lens like the 120-300mm F2.8 DG OS HSM.

Oh then sorry, mine is older than that...

bump

I tried before, seems like the build is kinda solid... as contemporary is a premium lens re-design by Sigma, quality wise should be better than previous model

Not sure the lens I tried is a demo unit or new unit, I found the zooming part not as smooth as my Nikon lens, hope other forumer can give comment on this...
