Pentax Helicoid Extension Tube K

PentaxForums.com Marketplace Listing

Item for Sale
Pentax Helicoid Extension Tube K

Asking Price
90.00 USD (Reduced from $110.00)

Item Location
Coquitlam, BC (Canada)

Item Description
Pentax Helicoid Extension Tube K, with case and original box. The hard copy manual is not available, but a full color digital PDF copy, suitable for printing, of both the older and newest manuals will be supplied. (This is not the ugly photocopied one supplied by Pentax)

It is continuously variable between 26.5mm to 46.5mm and at itsí longest extension it is roughly equivalent to using a #2 and a #3 Extension tube stacked . It will function with almost any lens, but using a reversed 28mm lens, depending on the lens model, you can achieve a magnification of from 3.42 to 3.74 times life size.

Auto aperture is not available with the Helicoid Extension Tube K, requiring manual stop down.

For anyone that is interested, but not familiar with this accessory, I would be happy to e-mail a copy of one of the manuals.

This is a ~very~ useful accessory -- it is ~so~ convenient to be able to vary the extension "on the fly" without having to swap extension rings around (and, if you need to, you could also stack this "variable ring" along with additional fixed length rings), and there is absolutely no "play" or "slack" in the helicoid mechanism.

Thanks for the endorsement Fred.

These are usually considered macro equipment, but they can be handy if you want to very close focus with a telephoto lens.
