The RF 28-70mm f\/2L USM leverages the unique capabilities of the RF mount to achieve a speed previously unheard of in a standard zoom. At f\/2, this lens gathers twice as much light as a traditional f\/2.8 zoom, allowing for incredible performance in low-light venues and delivering a shallow depth of field that produces painterly subject separation. As a premier L-series lens, it features a complex optical path including UD (Ultra-low Dispersion) elements and aspherical glass to maintain surgical sharpness even when shooting wide open. To handle the large glass elements, it uses a powerful ring-type Ultrasonic Motor (USM) for fast and nearly silent autofocus. While it is a significant piece of glass at over 1.4 kg, its build quality is uncompromising—fully weather-sealed and treated with Air Sphere (ASC) and Subwavelength (SWC) coatings to virtually eliminate flare. It also features the signature RF customizable Control Ring, putting precision adjustments for exposure right at your fingertips.\u003cbr\u003e\n\u003cbr\u003e\n\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003cbr\u003e\nMount Type: Canon RF\u003cbr\u003e\nFormat: Full-Frame\u003cbr\u003e\nFocal Length: 28–70mm\u003cbr\u003e\nMaximum Aperture: f\/2 (Constant)\u003cbr\u003e\nMinimum Aperture: f\/22\u003cbr\u003e\nLens Construction: 19 elements in 13 groups (including UD and Aspherical elements)\u003cbr\u003e\nAngle of View: 75° to 34° (Diagonal)\u003cbr\u003e\nFocusing System: Ring-type USM (Ultrasonic Motor)\u003cbr\u003e\nImage Stabilizer: No (Relies on camera IBIS)\u003cbr\u003e\nMinimum Focus Distance: 0.39 m (1.28 ft)\u003cbr\u003e\nMaximum Magnification: 0.18x (at 70mm)\u003cbr\u003e\nDiaphragm Blades: 9 (rounded)\u003cbr\u003e\nCoating: ASC (Air Sphere), SWC (Subwavelength Structure), and Fluorine coating\u003cbr\u003e\nFilter Attachment Size: 95 mm\u003cbr\u003e\nDimensions: Approx. 103.8 mm x 139.8 mm (4.1 in. x 5.5 in.)\u003cbr\u003e\nWeight: Approx. 1,430 g (3.15 lb)\u003cbr\u003e\n\u003cbr\u003e\n\u003cstrong\u003eIn the Box:\u003c\/strong\u003e\u003cbr\u003e\nCanon RF 28-70mm F2L USM Lens\u003cbr\u003e\nLens Cap (Front)\u003cbr\u003e\nLens Dust Cap RF (Rear)\u003cbr\u003e\nBayonet Lens Hood\u003cbr\u003e\nDrawstring Soft Pouch\u003cbr\u003e\nUser Manual","brand":"Base Electronics LLC","offers":[{"title":"Default Title","offer_id":47040813596821,"sku":"ACACCNN00026","price":2707.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0772\/3961\/5637\/files\/canon-rf-28-70mm-f2l-usm-lens-1.jpg?v=1772768803","url":"https:\/\/baseelectronics.us\/products\/canon-rf-28-70mm-f2l-usm-lens","provider":"Base Electronics LLC","version":"1.0","type":"link"}
