{"product_id":"canon-rf-10-20mm-f-4-l-is-stm-lens","title":"Canon RF 10-20mm f\/4 L IS STM Lens","description":"\u003cp\u003eThe Canon RF 10-20mm f\/4 L IS STM Lens achieves something genuinely rare in full-frame optics: a rectilinear 10mm minimum focal length that captures an extraordinary 130-degree diagonal field of view without the curved-line distortion of a fisheye, making it the widest rectilinear zoom lens Canon has produced for the EOS R system. This capability opens creative and practical possibilities for landscape, architecture, interior, real estate, and environmental portrait photographers that no previous RF zoom has offered — the ability to include expansive foregrounds, dramatic skies, and entire interiors in a single sharp, geometrically accurate frame. At f\/4 constant across the entire 10–20mm range, it maintains consistent exposure and depth-of-field control whether you are shooting wide vistas or tight interior spaces, and its L-series construction ensures the optical quality matches the ambition of its specification.\u003c\/p\u003e\u003cp\u003eThe optical formula features one Super UD element, three standard UD elements, and three aspherical elements working in combination to suppress chromatic aberration, distortion, and edge softness across a focal range that would challenge any conventional design. Sub-wavelength Coating (SWC) and Air Sphere Coating (ASC) are applied to critical surfaces to reduce flare and ghosting in the strongly backlit conditions that ultra-wide shooting — especially against bright skies and architectural glass — regularly produces, maintaining the contrast and colour accuracy that differentiates L-series results. Edge-to-edge sharpness and consistent illumination across the full image circle ensure that architectural lines render with precision from corner to corner, a standard that interior and architectural photographers in South Africa will immediately recognise as essential for professional delivery.\u003c\/p\u003e\u003cp\u003eA stepping motor (STM) autofocus system delivers quick, smooth, and near-silent focusing performance that is optimised for both continuous video autofocus and responsive stills acquisition, with full-time manual focus override available at any point without mode switching. Built-in optical image stabilisation compensates for up to five stops of camera shake independently, extending to six stops of combined stabilisation when paired with an IBIS-equipped EOS R body — enabling confident handheld shooting at the slow shutter speeds that low-light interiors, dawn landscapes, and blue-hour architecture demand. The weather-resistant L-series barrel withstands the outdoor conditions of South African location shoots with reliability. Available now from Foto Digital World in Pretoria with nationwide delivery across South Africa.\u003c\/p\u003e","brand":"Canon","offers":[{"title":"Default Title","offer_id":55132123463979,"sku":"6182C005AA","price":46795.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1003\/2975\/0827\/files\/canon-rf-10-20mm-f4-l-is-stm-lens-front.webp?v=1788102087","url":"https:\/\/www.fotodigitalworld.co.za\/products\/canon-rf-10-20mm-f-4-l-is-stm-lens","provider":"Foto Digital World","version":"1.0","type":"link"}
