A good 28-70 (app) lens for K100?

I'm looking for something comparable in quality to the Tamron 28-75 but lighter for a K100. I tried the Sigma 70 macro (about the same weight as the Tamron), and while that might work on the larger K10/20, that 500g + feels to forward-leaning and unablanced on the K100.

I don't much care about macro, but I do want high IQ. Am I on a fools errand or can I get quality in a fast (f/2.8 would be great) and light lens for general use?

Simple, the FA 28-70mm f/4 is small, light and compact and gives good image quality. Constant f/4 with aspherical element. And it's cheap too.

all "2x-7x" w/ 2.8 are FF lenses - so they can't be "light"... unless you will go for some less qualify 2.8-4.x (Sigma has one for example @ ~250g - 28-70mm F2.8-4 DG - but certainly it is not a high IQ lens)... or something like Tamron 17-50/2.8 @ 430g and 67mm filter - not big.

Can you define comparable in quality?

If you mean as sharp and as fast, it will not be lighter.

If you want a reasonable quality, stopped down, It is a little soft wide open, and not as fast as the tamron, look at the pentax FA 28-80 F3.5-4.6 Power zoom.

I picked one up for $10

here is the link to the person w/ many photos taken w/ that lens and you
can see the quality in higher resolution (1800 x 1200).

I recently bought the FA 28-70 f4 and its a great lens and very light as well. My previous 'walk-around' was the A35-105 which must weight twice as much, but it may be a fraction sharper (and has manual focus of course).
