Canon Extension Tube EF 25mm II noma

The Canon Extension Tube EF 25 II is a non-optical extension ring that increases the distance between the lens and the sensor. This reduces the minimum focusing distance and increases the magnification ratio, making it useful for close-up and macro photography with standard lenses. The extension tube is available from the BFS equipment rental service.

The EF 25 II adds more than 25 mm between lens and sensor. It carries all EF lens contacts, so data transfer between camera and lens is complete and all exposure programs are retained, except spot metering.

• Extension: more than 25 mm
