Use of Pentax Auto Extension Tubes

Hello:

I have not had success using my set of 3 Pentax-brand auto extension tubes with my 18-55 Auto lens and Pentax K-r body. Is their use limited to manual lenses that have an aperture ring? Any advice on extension tube usage would be much appreciated.

I have happily shopped at B & H and will continue to do so. Thanks for the great service.

Be well,

Bob

The Pentax tubes do require an aperture ring, yes. You may be able to find some used third-party ones with A-type contacts, or use a de-glassed teleconverter, but Pentax never made any of their own.
