Canon EF-S 55-250mm f/4-5.6 IS STM Lens 8546B002

EF-S Telephoto Zoom for APS-C DSLRs

The Canon EF-S 55-250mm f/4-5.6 IS STM is a telephoto zoom lens built for Canon APS-C DSLR cameras using the EF-S mount. It covers a 55-250mm focal range, delivering an 88-400mm equivalent angle of view on those bodies. The variable maximum aperture runs from f/4 at the wide end to f/5.6 at 250mm, stopping down to f/32. It suits photographers wanting affordable reach for sports, wildlife or travel.

Optical Stabiliser and STM Motor in Extended Use

Optical image stabilisation helps steady handheld shots at longer focal lengths where camera shake is magnified. The STM stepping motor drives focus quietly and smoothly, which benefits video recording by avoiding drive noise on the soundtrack. The rear focus system moves only the rear group, so the front element does not rotate during autofocus, keeping polarising filters effective. One ultra-low dispersion element and Super Spectra coating reduce chromatic aberration and flare during prolonged shooting sessions.

Lightweight Mount with 58 mm Filter Thread

The lens mounts directly to any Canon EOS camera with an EF-S mount without an adapter. Its 58 mm filter thread accepts standard circular polarisers and ND filters; the front element does not rotate, so filter orientation stays fixed. The minimum focus distance is 2.79 ft (0.85 m), allowing close-ups at the long end. Buyers needing full-frame coverage or a constant f/2.8 aperture should look elsewhere, as this design is optimised for APS-C sensors only.
