Comments about Kenko Kenko Teleplus MC-7 "DG" 2x AF Teleconverter for Pentax AF:
I found this teleconverter was not conpatible with AE and AF system of my Pentax K20 and Pentax DA* 50-135, and so retuned it.

Comments about Kenko Kenko Teleplus MC-7 "DG" 2x AF Teleconverter for Pentax AF:
The device was stated to work with Pentax DA lens. It does not work with my Pentax DA 50-135 zoom, in that it stops the electronics of the camera working. It works perfectly with my Sigma 70-300 zoom (except for autofocus which is not to be expected)with no electronics problems. It partly works with my sigma 70 mm macro lens in that it requires a -2ev exposure correction. It requires this same exposure correction with my Pentax 50 mm f 1.4 lens which otherwise works correctly.
When it works it does everything that is expected with no difficulty. I have had some very pleasing results, except that It does not work on one Pentax lens.
