Pentax Auto Extension Tube A Macro Set 645

The Pentax Auto Extension Tube A Set is designed for use with the Pentax 645 medium format system, allowing for close-up and macro photography with any Pentax 645 lenses. By increasing the lens-to-film (or sensor) distance, these extension tubes let you achieve greater magnification and tighter focusing distances without adding extra optics—preserving the original lens’s sharpness and rendering.

This is the “A” series set, meaning it maintains aperture automation when used with Pentax-A, FA, and D FA 645 lenses, ensuring smooth integration with both film and digital Pentax 645 bodies. Perfect for exploring macro subjects such as flowers, product photography, or fine detail work in medium format.

Condition: Excellent

This Pentax Auto Extension Tube A Macro Set is in excellent condition, with clean mounts and smooth operation. Electronics and mechanical couplings are intact, and the set shows only minimal handling wear.

A rare and useful accessory for any Pentax 645 shooter who wants to expand into macro and close-up work without needing a dedicated macro lens.
