The 1.4x HD PENTAX-DA AF Rear Converter AW from Ricoh is compatible with Pentax KAF2 mount lenses on select DSLR cameras. It mounts between the camera body and lens, and increases the focal length of the lens by 1.4x, while reducing the aperture by 1 f/stop. The minimum focus distance of the lens is preserved, as are auto focus and auto aperture functionality. The rear converter works flawlessly with both the camera-driven AF system and the lens-driven AF system, including that of the SDM and DC-series lenses. The camera's firmware must be updated to the latest version before using the autofocus function.

Pentax 1.4x AW AF Rear Converter Reviews
Good When it's Needed
I seldom use a teleconverter these days. I shoot mostly landscape (my passion) and wildlife. I want clear, crisp images. The Pentax 1.4 teleconverter is occasionally handy, but it will soften your images a wee bit and you will lose an f-stop. This image of a wild turkey was shoot with the KP and 300mm Pentax lens and the 1.4 teleconverter. I was on my knees keeping a low profile to get the shots I did and the teleconverter was a big asset on this particular day.
Finally in my bag
After years of shifting priorities, I've finally acquired the converter. So glad the price dropped $200. Now, I can finally use the AF feature with an extender; which was not an option with the Vivitar 2x Extender I still have from my Pentax film days. Works as designed, so smooth.
