Originally posted by Old Timer 56 When one of my K10D bodies came back from Pentax repair (autofocus issue), it consistently underexposed by about 2/3 stop, regardless of exposure mode, including manual. Same story with all meter modes and any subject or light condition. I mostly shoot in AV so I corrected with Exposure Compensation rather than send it back to Pentax. I didn't want to risk them screwing up something else. Previously the exposure was right on the money.
Oh, they did manage to fix the autofocus problem.

That's a bit of a downer isn't it.
I seem to have solved my problem by simply cleaning the contacts on the lens. As it is probably my most used lens along with my 50mm I guess it just got a bit grubby.
I don't expect it to last forever, but a little longer would be nice
.
As for the Tamron 90, this is the only review of it I have seen that was negative. I'm not that proficient myself, so I am sure that it'll do what I need it too.
Thanks for the help and advice guys.
