Mount Type: Canon RF (for full-frame mirrorless cameras) Focal Length: 70–200mm — versatile telephoto zoom range for portraits, sports, events, and wildlife. Maximum Aperture: Constant f/2.8 — great for low-light shooting and creating shallow depth of field. Image Stabilization (IS): Up to 5 stops of optical stabilization for sharper handheld shots. Autofocus System: Dual Nano USM motors — fast, smooth, and nearly silent AF for both photo and video. Optical Design: 17 elements in 13 groups, including UD and Super UD glass to reduce chromatic aberration. Coatings: Air Sphere Coating (ASC) — minimizes ghosting and flare for improved contrast and color. Minimum Focusing Distance: 0.7m (2.3 ft) — allows semi-macro close-up shooting. Aperture Blades: 9-blade circular diaphragm — produces smooth, pleasing bokeh. Build Quality: Premium L-series construction — dust- and moisture-sealed for professional durability. Compact Design: One of the smallest and lightest 70–200mm f/2.8 lenses ever made, ideal for portability. Filter Size: 77mm Weight: Approximately 1070 g (2.36 lb) — lighter than its EF predecessor. Fluorine Coating: On front and rear elements to resist fingerprints, dust, and water. Zoom Mechanism: Extending zoom design for a more compact retracted size.
