Comments about Sigma Sigma 2x EX DG APO Tele-Converter AF for Pentax AF Cameras:

I made the decision to purchase after satisfying results with its little brother, the 1.4x EXDG. I was rather surprised and disappointed at the performance of this version. While I expected some image degradation, the very high IQ of the K20D plus some sharpening in Lightroom should have compensated, IMO, but it did not.

Not compatible with Sigma 70-200mm lens!

Comments about Sigma Sigma 2x EX DG APO Tele-Converter AF for Pentax AF Cameras:

I bought this to use with a Sigma 70-200mm f/2.8 EX DG HSM (and a few other initials I forget). After much testing and no acceptable results, I found a page on the Sigma Japanese site that says that it is not compatible with my lens, but is with the non-HSM version - I hadn't checked the initials on the lens compatibility list close enough. It may be a fine product, but it confused my camera's light sensor and didn't fit any of my other lenses, so I returned it.
