Pentax k-x not working with my tamron lens, or older pentax lenses

I just got a new pentax K-x for my birthday! It is white.
It works with the Pentax-DA lens that came with it.
However, I have a tamron 28-300 mm it does not take a picture. The camera blinks F---
The camera also does not work with my old Pentax lenses: A panoramic 1:1.4 50 mm and a 75-150mm lens. I can see just fine through the view finder but won't take a picture.

Please advise.

Are the lens AF? If they are have you put the lenses on the A setting, otherwise , the F--- will show there

See page 94 of the manual

You have to "enable aperture ring" and I can't tell you where that setting is on the KX, you have to find it yourself!

There is also a sticky on this in the beginner's section.
