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.

There are automatic extension tubes that allow use of the lens in
aperture priority mode. What, pray tell, is "on-the-lens focusing"? I
can focus all my lenses when using extension tubes. Is this a
description of what happens with auto focus lenses?

Thank you, Shel - I didn't know there was such an animal as a helicoid extension tube,
but I'll check it out now.

I've owned both but never at the same time, so it's not quite a "side by side"
comparison, but the Pentax tubes have a nice

I've had both and I can assure you that there's no functional or per
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

Hi,
I have a perfect, like new set of the Vivitar tubes, and they are OK.
However, having tried a friend's Pentax set, I'd give up the Vivitars in
a NY minute. In fact, I bid on a few sets on ebay. The pentax just

highly, too.
I feel this way about some polycarb lens bodies: they just don't have the

Obviously, there's a big payoff in battery life (due to weight savin
