ROWI 2x tele-konverter wide extender lens converter barlow objektiv lente duplicador (M42 mount)

Description: very good condition. M52 threaded mount. Includes pouch and caps (both soft plastic push-in). Rare lens. It seems barlow and wide at the same time, depending on the way you insert them in your optical train.

Issues: could have some vintage traces (lenses are nice).
