VERY GOOD ZOOM LENS. I USE IT ON A PENTAX K3 (APSC) SO AT 320 mm IT PROVIDES THE FIELD OF VIEW OF A 500 mm (FF 35 mm EQUIVALENT). I USE IT BETWEEN f/8 AND f/13 ON A TRIPOD AND I GET EXCELLENT RESULTS. SUPERB COLORS AND CONTRAST, GREAT SHAPRNESS. AN EXCELLENT VALUE. IT COMPLETES MY "TRAVEL KIT" : ONE FA 20-35 mm WIDE-ANGLE, ONE FA 28-70 NORMAL AND ONE 80-320 TELEPHOTO. RICHARD

This review only rates the lens I had, not all Pentax 80 - 320 lenses. This lens was very nice mechanically, but had optical problems. I think that the Pentax 80-320 zoom lens is a good lens but it is older and some might have problems and some might be excellent. I will keep searching until I find the latter.

There's really nothing terribly special about this lens, other than the fact that it's got a good long zoom at a low price. The picture quality is a bit drab. Really bad purple fringing in high contrast photos. AF has a really hard time in low light. For being a plasticky build, it does feel solid enough. It's fairly light for its large size. Haven't had any problems with zoom creep. Front lens does rotate with focusing, so it's no good for polarizing filters. I'm a budget hobby photographer, so I'm satisfied with it. If you can't afford some fancy high dollar glass and you need a long zoom, you should be pretty happy with this one.
Great lens! Excellent condition! Works great on all my Pentax cameras!

I had purchased this Lens for my Pentax K100D. Found that it is a good lens, but it seems to loose focus when extended out to 320mm. Just does not fully focus at this high extension. The Lens is in real good shape, despite being used previously. It does take a sharp Image, but only below 300mm.
