Vivitar's 1.4x Teleconverter for Pentaxadds another valuable tool to your camera bag, at a very affordable price. This compact and lightweight 1.4x teleconverter multiplies the focal length of any compatible lens by 1.4--a 100mm lens with this teleconverter attached, for instance, would give you the view of a 140mm lens. The multi-coating on the converter reduces flare and ghosting, common problems with digital cameras. And, the minimum focusing distance is unchanged. This teleconverter comes with a lifetime warranty.

          Comments about Vivitar 1.4x Teleconverter for Pentax:

          Use with Pentax K10D and a couple of Pentax lenses. I have only taken a few test pictures so far. I hoped the AF would work will all lenses. It worked with the SMC Pentax-FA 1:1.4 50 mm but not the SMC Pentax DA 18-135 F/3.5-5.6. Instructions stated max. aperture of lens to ensure AF operation is F/4.5 or faster. I am satisfied with the quality of the images I have taken so far. It works well in MF on lenses that do not AF.

              Won't work on manual focus with lenses with focusing motors on my K5 because it affects the controls and menus. Does work with screw focus drive lenses. I have a 1.4 Tamron and a 1.5 Kenko for the Pentax K and they work with all lenses on the K5 and K20, but they are no longer available. I didn't test the sharpness but imagine it is close to the Tamron and Kenko which are pretty good. Vivitar seems to be the only game in town.

              Comments about Vivitar 1.4x Teleconverter for Pentax:

              I am traveling and using this TC with a rather slow lens (Tamron 70-300f4-5.6). The TC seems flimsy compared to my Pentax brand TC, but seems to deliver reasonably sharp images (good enough for bird ids anyway). The autofocus is very slow, exposure with the TC seems to be very good. At the price I think it is a good deal.

                I'm going to have to bring it back because using it prevents autofocus as well as autozoom.

                  i got this to get that little bit more without loss of image. it worked better then i expected with my 55-300mm pentax lens and k-5 body, showing no issus with light or focus. i would recommend if you looking to get a bit more for hand held bird photography. very fast delivery over seas
