Pentax-F 35-70mm F3.5-4.5 vs Pentax-A 35-70mm F3.5-4.5

I have an opportunity to buy either one of these lenses, both affordable and the F version about double the price of the A lens.

The pull-push A lens seems interesting while the F lens offers AF.

Does the 2 lens offer the exact same IQ? I looked at some pictures at our review sections and the pictures of the A lens looks more appealing, however it might be affected by the light condition, camera, etc.

Does anyone try both lens before and is able to give a comparison of the 2?

I don't have both lenses, only the F version, but looking at Bojidar Dimitrov's site Pentax Zoom Lenses with Medium Focal Lengths both lenses seem to be optically identical. So I guess it's a matter of whether you prefer auto focus or manual focus.

I've never used the A version. But I'm still kicking myself for selling my F35-70. Great little lens.

Get the F if it is resonably priced, I got mine with a good SFX for 70 euros.
The lens has a nice macro function, and it is so compact. Only its color is not that appealing.

I won my F35-70 and SFX on eBay for US$21 (together, shipped) a few months ago. It's a splendid little lens. I haven't tried the A but I'm not real keen on push-pull zooms; too many are a bit imprecise. My vote: go for the F.
