My apologies for being metric but 17-50 weighs 430 g (or so) and 28-75 weighs 510 g (or so). As far as my non-metric knowledge goes, 80 g is nowhere close to 1/2 pound... I've Tamron 28-75/2.8 and it seems my copy is outstanding. On Pentax DSLR it yields angle of view similar to that of 43-110

The Sigma is excellent, I used to own one when I had a K10D. I'm currently a very happy owner of the Tamron 17-50, but I'm a wide guy rather than preferring the long end. -Adam On Fri, Sep 3, 2010 at 11:19 AM, eckinator wrote: > Sam, > if you don't mind losing an f-stop there is always a 17-70,

Sam, if you don't mind losing an f-stop there is always a 17-70, either f/4 by pentax or f/2.8-4.5 by sigma cheers ecke 2010/9/3 Sam L : > Hi all, > > I'm fantasizing about acquiring an "upgrade zoom" from the pentax kit > lens and am currently thinking that the race is between the tamron > 17-50

Tamron 17-50 vs 28-75 ?

Hi all, I'm fantasizing about acquiring an "upgrade zoom" from the pentax kit lens and am currently thinking that the race is between the tamron 17-50 and the 28-75. I tend to like the longer end of a lens more than the wider end, so I think I would not miss too much the 17-27mm. I'm happier tak
