Dear all,
I am thinking to upgrade my 18-55mm to a better IQ and speed:
What would you pick again if you have a better choice for the standard general purpose walk around/travel lens:-
Sigma 17-70mm f/2.8-4.5 DC
Sigma 18-50mm f/2.8 EX DC
Tamron 17-50mm f/2.8 XR Di-II LD
Pentax SMCP-DA 16-45mm f/4.0 ED AL
worth the price???
Pentax DA 17-70 f4 SDM
Pentax DA* 16-50 2.8
The qualities I'm most interested in are: resolution, contrast. Next most important is speed. Lesser of importance is bokeh (Unless it's BAD bokeh, I heard some said Tammy 1750 does harshy bokeh), and last is AF speed/noise. Zoom range is the least important, they're all "within range", though it's usefulness (especially up to 70) can't be denied. Minimal vignetting/softness can be important too (of course!) One can only take so much p/p
It's to be used as a general purpose lens, aiming for significantly better quality (mainly in terms of resolution/contrast) than the kit, and a bit faster wouldn't hurt!
