This Wirgin Edixa Reflex extension tube set can be used with any M42 camera and lens, as long as you don't need automatic stop-down functionality: lenses with an "M" mode only, please. Includes tubes #1 (2mm), #2 (5mm), #3 (13mm) and #4 (30mm). Note that the #1 tube is an "accessory" tube and is designed to wedge between another tube- or lens- and a mount. Its function (and your comfort using it) may vary depending on the depth of threads on your lens. Tubes are in very good condition, with light surface wear.
