PENTAX Auto Extension Tube K 100mm

100mm extension tube in PENTAX K-mount. Can be combined with other extension tubes.

This tube has coupling for the aperture stop down lever. With cameras with a full-function K mount, metering can be be done with open aperture. On a DSLR, only "Green Button" stop down metering is available.

Lenses with an "A" setting must be used off the "A" setting since this tube has no lens information contacts.

Lenses without an aperture ring will be stopped down to their smallest aperture during exposure.

Focusing is to be done manually, also with autofocus lenses.
