good shutter speeds

A well made tripod that will almost certainly last longer than the social acceptability of referring to an inanimate object of commerce as a "Sherpa

Pentax Rear Converter-A 2X-S &nbsptype_Adapters good shutter speedsThe Pentax Rear Converter A 2X S is a 2x teleconverter compatible with most Pentax K mount lenses. Pentax says it's not compatible with its 15mm f3. 5 lenses or the 24 35mm f3. 5 zoom, and there may be a few others out there, too, so check your lens instruction manual to be sure. In excellent condition, with clean glass and only minor cosmetic wear.
