 "Canon EF 40mm f/2.8 STM Lens - 6310B002" 6310B002 | Texas Media Systems"
"The Canon 40mm f/2.8 STM lens is a standard Canon EF-mount pancake lens. Its squat stature makes it an unobtrusive lens: easy to wield and easy to store. The STM stepping motor functions quietly and allows for continuous autofocus when shooting video.

The EF 40mm has a wide aperture of 2.8 which, combined with its seven diaphragm blades, creates a beautiful, creamy bokeh. The lensâs configuration includes an aspherical element that guarantees a sharp image covering the full frame.
