The Extension Tubes EF12 II / EF25 II (Photo 3) are close-up photography accessories for EF lenses that are mounted on the rear of the lenses. While inheriting the basic specifications such as tube length from the EF12/EF25, the EF12 II / EF25 II have a larger inside diameter than previous models so that it can be attached to the EF-S18-55mm f/3.5-5.6 USM that protrudes at the rear.

Since attachment alignment is different with the EF-S18-55mm f/3.5-5.6 USM than with other EF lenses, the Extension Tubes EF12 II / EF25 II have two different mounting indexes at the front of their body: a red round index for EF lenses and a white square index for the EF-S18-55mm f/3.5-5.6 USM.
