Being a 7 element design made by Teleplus (Kenko) it should be good and I was very pleased with the quality when it arrived today. I had intended to take it apart and mount a 1.5X TN inside but it's too good as a 2X, so I will keep it as it is.The other bonus with this type of focusing teleconverter is the helical action, it gives around 20mm of travel which allow you to focus the scope as you would a regular lens. You can quickly focus somewhere near with the scopes crayford focuser and then switch the helical focus of the teleconverter to fine tune.I plan to get another one, probably the cheaper Vivitar version and then that will be the one I take apart. Mounting a TN in the front will allow a 20mm travel and therefore alter the magnification giving a zoom effect.I've posted a couple of photos taken with the teleconverter and also two of the teleconverter itself, one showing it retracted and the other showing it extended.Paul.</blockquote>
