Designed to be attached between a Canon RF-mount camera body and lens, this FotodioX 35mm Pro Automatic Macro Extension Tube allows the lens to focus closer than its normal minimum focus distance. By placing space between the camera body and lens, focusing distance is shortened and the effect of magnifying your subject is created. Extension tubes enable macro performance for lenses not otherwise able to focus as closely and are also suited for near-range portraiture.
This extension tube is the longer of two FotodioX Pro Automatic macro extension tubes for Canon RF-mount cameras, which can be used individually or in combination to achieve your desired focusing result. A 15mm Pro Automatic Macro Extension Tube for Canon RF-Mount Cameras is separately available.
Extension tubes have no optical elements, so they do not degrade the quality of your lenses. These extension tubes support electronic communication between an attached camera and lens, enabling autofocus, image stabilization, as well as camera-controlled program, aperture-priority, shutter-priority, and manual modes. If an attached lens is also capable of generating Exif metadata when used with a directly compatible camera, this Pro Automatic Macro Extension Tube is designed to allow that information to be saved along with image files generated with a combination of the lens, the camera, and the adapter.
