Close-up Lens Close-up Lenses
These close-up attachments can be used with most EF lenses to provide a shorter minimum focusing distance with no loss of light. The 250D/500D series incorporates double-element achromatic design for maximum optical performance while the 500 series features single-element construction for maximum economy. The 250D is optimized for lenses between 50-135mm, while the 500D works best with telephoto lenses from 70-300mm. Manual focusing is recommended.

Available Sizes: 52mm, 58mm, 72mm, 77mm   Type: Screw-in
Extension Tube EF 25 & EF 12 Extension Tube EF 25 & EF 12 (II)
These close-up accessories maintain full electronic coupling between the camera body and lens, often providing greater magnification than is possible with close-up lenses. Can be used with most EF lenses, and are ideal for nature photography with single focal length telephotos. Manual focusing is recommended.

The result of using extension tubes is that the distance from the back of the lens to the film surface is longer, which means you can take photographs at shorter distances to the subject. Extension tubes are thus commonly used for macro photography and sometimes for close-up portraits.

When using the camera's TTL metering system, no exposure compensation will be required (exposure compensation is required for handheld meters).

This updated version II is now also fully compatible with Canon Digital EF-S lenses, as well as standard photo EF and TS-E lenses.

Extension Tubes EF 25 & 12 II are especially suited for close-focusing with wide-angle lenses. EF 12 II is compatible with all lenses, except 15mm f/2.8 fisheye, 14mm f/2.8L and MP-E 65mm f/2.8.
