Canon EF-S55-250ISSTM 55-250mm f/4-5.6 IS STM Lens

The Canon EF-S 55-250mm f/4-5.6 IS STM is a telephoto zoom lens built for Canon's APS-C DSLR lineup, delivering an equivalent focal range of 88-400mm in 35mm terms. This makes it a versatile option for wildlife, sports, travel, and portrait photography where reach matters. The inclusion of a stepping motor (STM) sets it apart from its predecessor, providing smooth, near-silent autofocus that is particularly beneficial for video recording on compatible Canon bodies. The optical image stabilizer, rated for up to 3.5 stops of correction, compensates well for hand tremor at the long end of the zoom range where shake is most pronounced.

Optically, the lens uses a 15-element, 12-group design that includes one UD (Ultra-low Dispersion) element to control chromatic aberration. The result is clean, contrasty images across most of the zoom range, with sharpness that punches above its price class. At just 13.2 ounces and under 4.4 inches in length, it adds minimal bulk to a camera bag, making it an excellent travel companion. The 58mm filter thread is widely compatible with affordable filters. While the variable f/4-5.6 aperture won't win any low-light battles, the combination of image quality, stabilization, and STM focus makes this lens a compelling choice for photographers who want telephoto reach without the weight or cost of L-series glass.
