Canon Extension Tube EF 12 II

The Canon 9198A001 is an EF 12 II extension tube that fits between your EOS camera body and a compatible lens so you can focus far closer than the lens normally allows. The 12 mm spacing moves the lens forward, turning an everyday optic into a tool for detailed close ups and macro work.

Eight electronic contact points inside the tube preserve communication between camera and lens, so autofocus and exposure metering continue to operate the way you expect. You can compose, focus, and shoot without changing your usual routine.

Photographers who enjoy capturing small subjects such as flowers, insects, jewelry, or textured materials will appreciate how the tube lets them fill the frame and reveal fine detail. Portrait artists can step in for tight eyes or lips without heavy cropping, and product shooters can present items at a scale that helps customers see exactly what they are buying.

The EF 12 II pairs with EF-S digital lenses as well as EF and TS-E models, giving you flexibility across a wide range of focal lengths. It is not compatible with the 15 mm f/2.8 fisheye, the 14 mm f/2.8L, or the MP-E 65 mm f/2.8 lens.

The housing is small and light, so it slips easily into any camera bag. Its purely mechanical extension shortens the focusing distance without compromising image quality. Keep it on hand for travel, studio sessions, or spontaneous walks, and attach it whenever you want to explore the details that are otherwise too small to see.
