Wirgin Edixa Reflex extension tube set extension tube You can cut your ownThis 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.
