Canon Extension Tube EF 25 for EOS

The Canon Extension Tube EF 25 is a dedicated macro accessory designed to shorten the minimum focusing distance of Canon EF lenses, enabling detailed close-up and photomacrography. By inserting a 25mm space between the camera body and the lens, it extends the distance from the rear optical element to the focal plane, allowing for higher magnification without adding extra glass elements to degrade image quality. Recommended primarily for lenses with focal lengths of 50mm and above, it maintains full electronic communication between compatible Canon EF and TS-E lenses and EOS camera bodies, ensuring accurate TTL autofocus and exposure metering without manual compensation calculations.
