FA* 28-70 F2.8 - what to look for?

My local store has one of these at a satellite store they are bringing in for me, it's a lens I feel I should have in the collection for a few reasons... but I want to know what I should be looking for to make sure I'm not spending a thousand dollars on a bad copy.

I'll also be getting the FB-1 FC-1 finder combo for my LX.

Yes, my LX is getting two Christmas presents.

Check that the focus ring and zoom rings work and can switch between manual and autofocus/power zoom, respectively. Aperture blades snappy, no scratches and blemishes on the glass. Lens hood should be included.

If you bring your K-3 or K-5 with you take some images and verify that autofocus works, power zoom works, aperture mechanism works (in Av mode you should get same exposure at all F-stops).

Check sharpness across the frame and zoom range, corner sharpness should be similar in all corners or you may have a lens that was abused and got decentered.

It's a sturdy lens. Odds are that you'll find it in good order. I had two I bought second hand (one got stolen), and they were both in perfect condition.

Look out for thieves willing to risk everything to take it from you

Joking aside, it's the usual : damage to the glass, non-smooth rings operation, cosmetic flaws, fungus.

thanks, I figured as much.

I know when hunting for the 31 there were things to watch out for like girding on the rings and play in the hood (which saved me from a potentially bad copy). I appreciate the additional tips on this one.
