Pentax Microscope Lens Adapter K & new Achromatic 10X Objective lens

Asking Price
130.00 USD

Item Location
Coquitlam, BC (Canada)

Item Description
The Pentax Microscope Lens Adapter K is macro accessory that brings us into the realm of extreme macro photography. Extreme Macro photography, or photomicrography is undefined but is generally accepted as making images that are between 1:1 (life size) and microphotography which uses microscope equipment, and is usually 10:1 (10x life size), or greater.

Microscope lenses, such as this Achromatic 10X microscope Lens from AmScope, are less prone to diffraction softening at high magnifications than some reversed lens options. This long-discontinued item seems to be a bit of a rare Pentax accessory as it is seldom seen for sale, and the earliest mention I can find is in in the “Asahi Pentax Lenses and Accessories” brochure circa 1979 and the latest mention is in the same Pentax L & A Brochure circa 1989.

The Pentax Adapter K for Microscope Lenses is used (In like new condition) and provides a K Mounting flange and an RMS (Royal Microscopical Society) female thread (20.32mm)

The microscope objective lens is new: (SKU: PA10X-B)
