Usage

By inserting the EF-25II extension tube between the camera body and lens, photographers can achieve closer focusing distances, allowing for detailed close-up shots of small subjects such as insects, flowers, and other macro subjects. The extension tube does not contain any glass elements, so it does not affect image sharpness or quality. It is especially useful for wildlife photographers who require portability and flexibility in their gear.
