Telephoto reach for EF cameras

This Canon EF 75-300mm f/4-5.6 III zoom lens covers a versatile telephoto range on full-frame and APS-C bodies. The 75-300mm focal length lets you pull distant subjects closer for sports, wildlife or event photography without swapping glass. A DC micromotor drives autofocus through a front-group rotating extension system. It suits photographers who want affordable reach on Canon EF mount cameras.

Optical performance and handling

The lens construction uses 13 elements in 9 groups with Super Spectra coating to suppress flare and ghosting. A seven-blade diaphragm produces rounded aperture shapes from f/4-5.6 down to f/32-45. Minimum focus distance is 1.5 m with 0.25x magnification for close-up detail. Angle of view narrows from 32 degrees to 8 degrees across the zoom range for tight framing.

Filter thread and mount compatibility

A 58 mm filter thread accepts standard circular polarisers, ND filters or protective glass without vignetting at the wide end. The Canon EF mount fits all EOS film and digital SLR bodies as well as EOS R mirrorless cameras via an adapter. No image stabilisation is built in, so steady technique or a tripod helps at 300 mm. The package includes front and rear caps only.

Questions about this item

How do I attach the 58 mm filter thread and which step is often missed?

Screw a 58 mm filter onto the front thread; the front group extends and rotates during autofocus, so do not overtighten the filter or it can bind the focus mechanism.

What part will need cleaning or replacement after extended use?

The 13 elements in 9 groups have a Super Spectra coating; clean the front and rear glass with a microfibre cloth and replace the filter if the coating gets scratched.

At what focal length does the maximum aperture become the limiting factor first during sustained shooting?

At 300 mm the aperture narrows to f/5.6, so that is the first limit you hit for low-light exposure and depth-of-field control.
