Superior optics are assured by the use of three aspherical lens elements, in addition to a Super UD (Ultra-low Dispersion) glass element. Optical coatings are optimized for use with digital cameras. This lens focuses as close as 11 inches (0.28m), and offers both Canon's full-time manual focus and a powerful ring-type USM for fast and silent AF. It has a constant f\/4 maximum aperture, and offers the choice of screw-in 77mm filters or a holder in the rear of the lens for up to three gel filters. Finally, it offers weather-resistant construction similar to other high-end L-series lenses.\u003c\/p\u003e","brand":"Canon","offers":[{"title":"Default Title","offer_id":67098758676525,"sku":"U4505770","price":200.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0343\/5246\/3917\/files\/U4505770-1.jpg?v=1784761201","url":"https:\/\/thecamerastore.com\/products\/canon-ef-17-40mm-f4l-usm-used","provider":"The Camera Store","version":"1.0","type":"link"}
