Welcome to the forum.

Any Pentax K (bayonet) mount lens will work with your camera. Some restrictions apply however. You'll get a reasonable list of the restrictions from the K20D camera manual which you can download from www.pentaximaging.com.

My recommendation would be to stick to lenses having the A setting on the aperture ring, or lenses that have no aperture ring. leae he A lenses set to A and set the aperture from the body.

SMC Pentax-A lenses are manual focus, SMCP-F, FA, D-FA & DA are autofocus. The D-FA, DA and DA* lenses are optimized for use on DSLR's.

Any lens with the * (star) suffix is a top grade lens, fast, and expensive.

For now, I'd avoid buying SMCP or SMCP-M lenses as there are exposure/metering issues when used with the later Pentax/Sasmsung DSLR's.

Hi Peter thanks for the excellent info.

This might help although it doesn't go as far as the K20D

I would have thought the k20d/gx-20 would be take the same lenses as the k10d/gx-10

You would not be wrong.

An almost complete list of Pentax lenses that you can use with your camera is on this site:

You can use the pre "A" types - but some extra hassle will be involved. So stick to "A" and later - unless there is a particular advantage with a certain "M" or "K" lens for you.

There are also many Pentax compatible lenses from other makes, including Sigma and Tamron.
