Canon EF 40mm f/2.8 STM (pancake lens) in good shape, functions properly and reliably. Cosmetically, the exterior looks not great due to remnants of old gaff tape and some wear marks. The residue should come off with some cleaning efforts. This is a great low profile lens that makes the footprint of your EF mount camera significantly smaller, awesome for street photography or lightweight travel. Comes with original box, end cap and a clear UV filter. From Canon: A unique and indispensable addition to Canon's series of EF lenses, the EF 40mm f/2.8 STM offers an ultra-slim and lightweight design. Incredibly compact in size, the EF 40mm f/2.8 STM delivers high image quality from the center to the periphery thanks to its advanced lens configuration including an aspherical element, a bright 2.8 aperture, and optimized coatings that minimize ghosting and flare while providing exceptional color balance. The EF 40mm f/2.8 STM's unobtrusive design helps the photographer avoid overwhelming their subjects with a large lens and to remain discreet in sensitive shooting situations with no compromise in performance. Its diminutive design is complemented by features such as a newly developed stepping motor for smooth and quiet continuous AF while capturing video with the Canon EOS Rebel T4i DSLR, a circular aperture (7 blades) for beautiful soft-focus backgrounds, and a short minimum focusing distance of only 0.98 ft./0.30 m.
