5 out of 10 points and not recommendedcheap, small, IQmecanically weak
I am a Pentax K10D user. I bought this to replace the kit lens.reviewed October 27th, 2008 (purchased for $410)
The first one had some kind of front/backfocus problem so it was sent back, the second i got after a week had some centering fault i beleive and now i am waiting for the third lens.
I'we got my third lens and it was allright between 50-75 but between 25-50 very soft and the camera couldnt focus properly at distances over 2m on shorter distances i was ok. Even this lens was sent back.
Now i have got both my camera and lens calibrated but it is not what i hoped for and not as good as the test here shows, its sharp in the center from f2,8 and from f4 its almost sharp overall but the contrast i not what i have expected.
They who have problems with sharpness with this lens I would reccomend to calibrate both the camera and lens.
After using my lens for several months now i have reeditet my review, the lens overall i a dissapointment, its useful but nothing to rave about
I belive that the quality is very uneven, there can maybe be good lenses but there are many poor lenses too.

I use this lens on a Pentax K10Dreviewed October 28th, 2008 (purchased for $210)
After reading much reviews i found out that this lens can be veery sharp if you use it the right way and produces very good images.
Mostly i use it at f8 and 70-150 where it is at its best.
