Amazon.com: Pro Optic Auto Extension Tube Set for Pentax-KPR Mount, 3 Tubes.: Electronics
i sent e-mail to adorama whether af is available or not and i am waiting for answer.
ii couldn't find any alternative to "pro optic" which is a little expensive for me...
ii don't expect using af with 3 tubes, but i think i can use af up to 25 mm (like kenko's) if af is available like canon's pro optic extensions.
any suggestions???
thanks
halil

Let us know if Auto Focus and exposure is available with these tubes. Adorama is sometimes very slow at answering questions.
