Canon EF 40mm f/2.8 STM Lens For Canon DSLR Cameras

Introduction

This EF 40mm f/2.8 STM Lens
from Canon is a welcome addition to Canon’s line-up of EF lenses–a
light, inconspicuous “normal” lens. At a featherweight 4.6 oz, this is
one of the lightest lenses in the EF family. It’s less than one inch
long, so it will never draw unwelcome attention to you when you’re
shooting in public.

A bright f/2.8 maximum
aperture allows you to shoot under pretty much any lighting conditions,
and the sophisticated lens configuration, including one aspherical
element, guarantees high image quality from the center to the edge of
the frame. The optimized coatings used in constructing the lens greatly
reduce ghosting and flare, and deliver superb color balance.
