Original Praktica tele converter for bayonet mount SLR cameras and lenses (see below)

This is an original Prakticar tele converter suitable for Praktica bayonet and Jenaflex SLR cameras and lenses (see below), in very good condition with case and front/rear caps.

This converter fits between the camera and lens, and doubles the focal length. It can be used with just about any lens (except some very wide/old types, where the rear elements protrude too far), but works best with standard, telephoto and zoom lenses. A 50mm standard becomes a 100mm portrait lens, and a reasonably priced 70-210mm becomes a 140-420mm, which would usually be very expensive.

It couples to the camera's auto diaphragm and electric full aperture metering systems, compatible with manual and aperture priority auto exposure modes (see below). TTL metering systems (including TTL flash) will handle the exposure compensation required automatically. The close focusing distance of the original lens is retained, so you get extra magnification for close ups. A zoom lens that focuses down to 1:4 (one quarter life size) on its own will manage 1:2 (half life size) with the converter.

The converter adds only around 25mm (1 inch) to the length of the lens attached, and weighs under 150g. Coated glass to reduce flare. This Prakticar Auto Teleconverter is very nicely made (in Japan) with a solid, metal barrel and lens mounts, rubber grip and a high standard of fit and finish.

A great way to add extra focal lengths to your Praktica B or Jenaflex outfit!

Condition: Excellent+++ (8.5/10)
A very nice converter, in fully working order. All mechanical and electrical couplings work properly. The glass is very clean with no scratches, misting, fungus or other problems, beyond tiny specks of dust as usual, which won't affect the pictures at all. Cosmetically the black finish is smooth with just some surface marks here and there, plus small scrapes on the mounts where it's been attached to cameras and lenses. The caps and case are in good condition.

No dents, dings or deep scratches, and overall it's in nice shape!
At the time of listing we have more than one of this item, but the pictures and description here are representative of all of them.

Includes front/rear caps and case

Compatibility
This converter has the Praktica B electric bayonet mount, and fits all bayonet Praktica cameras, including the B100, B200, BMS, BCA, BC-1, BC-3, BCX, BX20 and BX20s and others. Also fits the Carl Zeiss Jenaflex AC-1 and AM-1 cameras, which use the same Praktica B lens mount. Auto diaphragm, full aperture metering with electrical contacts (a Praktica innovation!) and compatible with auto and manual exposure modes.

It DOES NOT fit older Praktica screw mount cameras, or any other make of camera. Adapters are available for use on Micro Four Thirds digital cameras, but only with Praktica B lenses - not digital ones.
