Canon EF-S 55-250mm f/4-5.6 IS II Lens

Canon EF-S 55-250mm f/4-5.6 IS II Telephoto Zoom Lens
The Canon EF-S 55-250mm f/4-5.6 IS II is a compact, lightweight telephoto zoom lens designed exclusively for Canon APS-C format DSLRs utilizing the EF-S lens mount. Delivering an impressive 88-400mm full-frame equivalent focal length range, this lens brings distant action, sports, wildlife, and details incredibly close. Outfitted with a 4-stop hardware optical image stabilizer and a specialized aberration-reducing optical formula, it stands as the perfect, high-value companion lens to standard 18-55mm kit optics, offering extensive telephoto reach in a highly portable design.

Extended Telephoto Reach & Corrective Optical Formula
88-400mm Equivalent Zoom Spectrum: Seamlessly bridges the gap from mid-telephoto portrait lengths up to a powerful super-telephoto reach, making it effortless to isolate faraway subjects or compress background perspectives.

Ultra-Low Dispersion (UD) Glass Element: Incorporates one premium UD lens element within the optical construction to aggressively minimize color fringing and chromatic aberrations. This ensures high edge-contrast, rich clarity, and strict color fidelity across the entire zoom range.

Super Spectra Lens Coating: Individual glass elements feature Canon’s multi-layered Super Spectra coating to suppress surface reflections, internal flare, and ghosting. This treatment maintains excellent contrast and color neutrality, even when shooting in bright sunlight or highly backlit environments.

Rounded 7-Blade Diaphragm: Built with a circular seven-blade iris configuration that yields a smooth, natural out-of-focus background blur (bokeh) when employing selective focus or shallow depth-of-field techniques.

Hardware Image Stabilization & Agile Autofocus
4-Stop Optical Image Stabilizer (IS): Features an advanced, built-in optical stabilization system that counteracts the blurring effects of handheld camera shake by up to four stops. This technology is vital for capturing crisp, tack-sharp imagery at slower shutter speeds or when shooting handheld at the maximum 250mm telephoto extension.

DC Micro Motor Autofocus System: Driven by a quick and responsive DC Micro Motor focus configuration that provides reliable focus acquisition for everyday snapshot and action photography.

Dedicated AF/MF Toggle Switch: Outfitted with a physical toggle switch on the side of the lens barrel, allowing you to instantly swap between automatic tracking and manual focusing methods on the fly.

3.6′ Close-Up Focusing: Maintains a close minimum focusing distance of just 3.6 feet (1.1 meters) across the entire zoom spectrum, allowing you to fill the frame with nearby smaller subjects like flowers, foliage, or tight portrait details.
