The Canon EF-S 17-85mm f/4-5.6 IS USM is a highly versatile standard-to-telephoto zoom lens designed exclusively for Canon APS-C format DSLRs utilizing the EF-S mount. Delivering a practical 27.2-136mm full-frame equivalent focal range, this lens serves as an excellent all-in-one choice that effortlessly covers everything from wide-angle landscapes and architecture to short-telephoto portraiture and sports crops. Outfitted with hardware optical image stabilization and a fast, quiet ring-type Ultrasonic focus motor, it provides an expansive framing spectrum for everyday shooting.
CONDITION NOTE (SOLD COMPLETELY AS-IS / REPAIR GRADE)
This lens is being sold strictly AS-IS for parts, repair, or specialized experimental use. It exhibits an optical defect that lowers its grade below standard working condition, making it an ideal project piece for lens restorers or technicians.
Included Accessories: Includes a front lens cap. Please note that the rear lens cap is NOT included.
Optical Fungus Warning: There is light-to-moderate optical fungus growth present across each glass element layer. This organic growth will cause a reduction in overall image contrast, increased ghosting/flare, and a soft, hazy “dreamy” look when shooting in bright or backlit environments. The lens must be disassembled and cleaned to restore its original optical performance.
Mechanical Status: The structural lens barrel, manual zoom mechanics, and physical switches are intact, though the electronic autofocus and image stabilization are untested or limited by the optical condition.
Expansive Focal Spectrum & Corrective Glass Elements
All-In-One 27.2-136mm Framing Reach: Eliminates the need to carry multiple lenses, allowing you to instantly jump from sweeping wide angles to compressed telephoto fields of view.
Dual-Sided Aspherical Element: Incorporates one specialized dual-sided aspherical glass element into its optical formula. This design helps minimize geometric distortions and spherical aberrations throughout the zoom range, working to preserve structural sharpness.
Super Spectra Layered Multi-Coatings: Individual elements feature multi-layered Super Spectra coatings designed to minimize internal surface reflections, ghosting, and lens flare—ensuring color neutrality and contrast under strong light (performance may be altered by the internal fungus).
Rounded 6-Blade Diaphragm: Built with a circular six-blade iris configuration that contributes a pleasing out-of-focus background quality (bokeh) when isolating subjects with shallow depth of field.
Hardware Image Stabilization & High-Speed USM Focus
3-Stop Optical Image Stabilizer (IS): Features a built-in optical image stabilization system that counteracts handheld camera shake by up to three shutter speed stops. This hardware enhancement helps enable sharper handheld shooting in low-light conditions or when framing at slower shutter speeds.
Ring-Type Ultrasonic Motor (USM): Driven by Canon’s premium ring-type Ultrasonic AF motor paired with an internal focusing system. This mechanical configuration delivers fast, precise, and quiet autofocus tracking.
Full-Time Manual Focus Override: Provides instantaneous creative control via a dedicated mechanical focusing ring, allowing you to fine-tune focus manually at any time without needing to switch out of autofocus mode.
