Lens Overview — Canon 100-300mm f/4.5-5.6 USM

The Canon EF 100-300mm f/4.5-5.6 USM is a telephoto zoom lens built around Canon's EF mount, covering a focal length range of 100mm to 300mm. Designed for full-frame cameras, it is equally compatible with APS-C DSLR bodies within the Canon EF ecosystem. The variable maximum aperture runs from f/4.5 at the wide end to f/5.6 at the telephoto end, offering a practical range for outdoor and available-light shooting across the telephoto spectrum.

Autofocus is supported, with both auto and manual focus modes available to the shooter. Weighing in at 540g, the lens sits on the lighter end of the telephoto zoom category, which can be a meaningful advantage for photographers spending long periods in the field. The 58mm filter thread is a common size, making compatible filters easy to source.

The lens is built for Canon's DSLR system and uses the Canon EF mount, ensuring broad compatibility across Canon's full-frame and APS-C DSLR lineup. There is no image stabilization included, which is worth factoring in when shooting at longer focal lengths or in lower light conditions.
