Canon Extender FD 2X + tussenringen Camera lens

Canon extender FD2x Type A + 2 FD extension tubes

For all Canon SLRs with an FD mount, this extender (= teleconverter) magnifies the focal length of any lens by 2x. You do lose 2 stops of light transmission. The extender is nearly new and is supplied in the original packaging with all factory documentation.
The two extension tubes, each with an FL/FD mount, can be used on nearly all Canon lenses and cameras with an FL or FD mount. This greatly reduces the minimum focusing distance. Both can also be used simultaneously.
The entire set with lens caps. The extender weighs 320 grams, the tubes 126 grams.
