Condition This Pentax 67 Rear Converter 2X is in very good condition and fully functional. While there are signs of use and scratches consistent with its age, it is in excellent condition considering how long ago it was manufactured. Please examine the photos carefully. The optics are clear, free of haze and fungus, and show no significant scratches. There is some minor dust present, but this does not affect image quality. Brief Description The Pentax 67 Rear Converter 2X is a genuine teleconverter for the Pentax 6x7/67 medium format system; it mounts between the camera body and a Pentax 67 lens to double the effective focal length. This offers a cost-effective way to extend the telephoto range of existing 6x7 lenses, albeit at the cost of two stops of light. Specifications Type: 2x Rear Teleconverter Mount: Pentax 67 bayonet mount (fits between body and lens) Effect: Doubles the focal length of the attached lens; reduces effective aperture by two stops Made in Japan Serial Number: 4129893 Included Items Pentax 67 Rear Converter 2X Front cap Rear cap Note: Original box and manual are not included.

Collector's Note For photographers who have already invested in the Pentax 6x7/67 system, the genuine 2x rear converter offers a practical way to gain telephoto reach without the expense and bulk of a dedicated long lens. For example, it allows you to transform the classic 105mm f/2.4 into an effective 210mm lens. As with other teleconverters, some reduction in contrast and sharpness compared to a native lens of the same focal length is to be expected, and the two-stop loss of light is worth keeping in mind when shooting handheld. In this instance, the optics are clear, making it a handy addition that is ready for immediate use with a 6x7/67 kit.
