I use the Vivitars with no problems. My set has the electrical contacts and work fine. However, they are too narrow to couple with the L series teleconverters, so avoid them if you plan to use them with the TC's. - MCC At 10:48 AM 11/13/01 -0800, you wrote: Hello all... Does anyone have

Thanks, Shel. These tubes represent my first foray into macro photography, so I can't justify a significant investment in Pentax gear yet. If I go beyond just experimenting, then I may spring for the good stuff later. If glass were involved, I wouldn't be quite so anxious to make a compromise. t
