Canon EF 35-80mm f/4-5.6 III Lens

The Canon EF 35-80mm f/4-5.6 III Lens is an extremely lightweight, compact standard zoom lens designed for Canon EF-mount film and digital SLR cameras, introduced in 1995 as an affordable, practical walk-around option. At just 175g, it was Canon’s lightest compact zoom EF lens, well suited to snapshot portraiture, travel, street scenes, and everyday casual photography.

Optically, the lens covers a 35-80mm focal range with a variable maximum aperture of f/4 at the wide end narrowing to f/5.6 at full telephoto, down to a minimum aperture of f/22-32, delivering a diagonal angle of view of 63 to 30 degrees. The 8-element, 8-group optical design incorporates an aspherical element, helping keep the lens compact while delivering high-contrast images, and lead-free glass is used throughout. A 5-blade diaphragm contributes to the lens’s background rendering.

Autofocus is handled by a micromotor-driven system (not USM), using a front-group rotating extension design, delivering functional but basic autofocus performance without full-time manual focus override.

Build quality centers on a compact, all-plastic barrel and mount, keeping the lens genuinely pocketable at approximately 65 x 63.5mm. It has a closest focusing distance of 0.4m (1.3 ft.) maintained across the zoom range, yielding a maximum magnification of 0.23x at 80mm, close enough to fill the frame with a postcard-sized subject. The lens accepts a 52mm filter thread and does not include image stabilization or weather sealing.

As a full-frame-compatible lens, the EF 35-80mm f/4-5.6 III produces its standard field of view on full-frame Canon bodies and an effective, narrower equivalent field of view (approximately 56-128mm) on APS-C bodies.
