Captain Jack's Canonflex Lens Page

The Canonflex was the first single lens reflex model offered by Canon. Canon lenses available for it ranged in focal length from 35mm to 1000mm plus a 2000mm mirror lens. They are known in most circles as "R" lenses. I am missing the 85mm preset lens and all of those above 400mm. I plan on adding them as my collecting luck and funds permit.

Should you have any of the lenses I am missing for sale, please contact me by clicking HERE.

Notes:

All of the Canon "R" lenses from 300mm to 1000mm require the use of the Canon Bellows R for focusing. In addition, they require the use of the Canon Lens Supporter R and the proper Canon Intermediate Tube. © All items on this site are copyrighted and are not to be reproduced without the expressed permission of Captain Jack.
