New in box, RED version.

COMPATIBLE WITH ALL CANON EOS CAMERAS

The photos are of my own tubes and own photos, of the same product.

The difference between these Macro Extension Tubes and the cheaper versions you see is these are Auto Focus & TTL which means you can use all your cameras advanced focus features and exposure features as you would with any Canon lens. Unless you prefer to manually focus and calculate your own exposures every time you will want this model. You can still operate manually with this model if you choose to also.

By attaching one of these lens extensions you increase the focal length of your lens from the sensor which means you can take photographs at shorter distances to the subject, thus magnifying the image.

Professional extension rings designed with all the circuitry and mechanical coupling to maintain Auto Focus & TTL auto exposure with most Canons. A high quality alternative to the highly expensive Canon Extension Tube EF 12 II & the Extension Tube 25 II.

Mounted between the camera body & lens, extension tubes have no optics so do not not affect image quality, you get the same image quality that your Canon lens currently produces, but magnified.

The 3 tube lengths that can be used individually or combined to provide up to 7 different lengths.
