I have a question about Kenko teleconverters

miyarui1013 · 01-14-2023, 12:01 AM

Hello! This is my first thread and I'd like to ask you a few questions. I purchased the smc PENTAX-DA ★ 50-135mmF2.8ED[IF] SDM yesterday. I have a question. Can I connect a KENKO PZ-AF 1.5 TELEPLUS SHQ to a lens that uses this SDM motor to work properly AF? I would like to know. My English may be strange because I used a translation software.

The PZ version of the Kenko 1.5x SHQ does indeed have the two additional contacts that are required, so I'm guessing it should work - but I haven't verified this in actual use. I have owned and used that particular teleconverter, and can say that I was satisfied with it's sharpness and screwdrive autofocusing capabilities.

Thank you so much! I'm so happy to here that!

I don't have the 2.8/50-135 but I use the same Kenko TC with other lenses with SDM AF motor.
I've tried it with the DA*4/300 and the DA* 60-250 zoom. Works well with both.

Likewise … mine is used when "I really need that little bit more reach" with my Sigma 150-500mm and it works well in good light on that lens. With an f/2.8 there should be no problems
