This high speed wide-angle lens offers photographers high imaging performance with an unmistakable visual signature.\u003c\/p\u003e\n\u003cp\u003eThe Leica Summilux-M 28mm f\/1.4 ASPH. rounds of f the range of high-speed M wide angle focal lengths. It offers excellent image performance over the entire image field even at full aperture and in the close-up range thanks to a floating element. With its exceptional contrast, the lens delivers the same recognized high performance level as the Leica Summilux-M 35mm f\/1.4 ASPH., and in some respects actually out performs it.\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cp\u003eThe vignetting that is typical of every optical system is naturally more defined on a wide angle lens, particularly a high speed one like this, than on standard lenses or those with a long focal length. At full aperture in 35mm format it is a maximum, i.e. in the corners of the image, of around 3.4 stops. Stopping down to 5.6 visibly reduces this light falloff – to 1.8 and 0.8 stops respectively. Stopping down further does not bring about any notable reduction as essentially only the natural vignetting remains. Distortion is extremely low for a wide angle lens at a maxi-mum of 1.1%, which is rarely noticeable in practice. A total of ten lens elements are used to achieve this exceptional performance. To correct color defects, seven of these are made of glass types with anomalous color dispersion (partial dispersion), while one has an aspherical surface. To maintain performance in the close-up range, one element towards the rear of the optical system is a “floating element” that moves independently of the rest of the mechanism.\u003c\/p\u003e\n\u003ch5 data-start=\"83\" data-end=\"113\"\u003eWhat Our Experts Think\u003c\/h5\u003e\n\u003cul data-start=\"114\" data-end=\"391\"\u003e\n\u003cli data-start=\"114\" data-end=\"182\"\u003e\n\u003cp data-start=\"116\" data-end=\"182\"\u003eUltra-fast f\/1.4 aperture for exceptional low-light performance.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"183\" data-end=\"239\"\u003e\n\u003cp data-start=\"185\" data-end=\"239\"\u003eSharp, high-contrast optics with minimal distortion.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"240\" data-end=\"318\"\u003e\n\u003cp data-start=\"242\" data-end=\"318\"\u003eCompact, durable design for professional street and landscape photography.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"319\" data-end=\"391\"\u003e\n\u003cp data-start=\"321\" data-end=\"391\"\u003eIdeal for photographers seeking precision and classic Leica quality.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5 data-start=\"393\" data-end=\"404\"\u003eQ\u0026amp;A\u003c\/h5\u003e\n\u003cul data-start=\"405\" data-end=\"850\"\u003e\n\u003cli data-start=\"405\" data-end=\"526\"\u003e\n\u003cp data-start=\"407\" data-end=\"526\"\u003e\u003cstrong data-start=\"407\" data-end=\"413\"\u003eQ:\u003c\/strong\u003e Is this lens compatible with Leica M cameras?\u003cbr data-start=\"459\" data-end=\"462\"\u003e\u003cstrong data-start=\"464\" data-end=\"470\"\u003eA:\u003c\/strong\u003e Yes, fully compatible with all Leica M-mount cameras.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"527\" data-end=\"610\"\u003e\n\u003cp data-start=\"529\" data-end=\"610\"\u003e\u003cstrong data-start=\"529\" data-end=\"535\"\u003eQ:\u003c\/strong\u003e What is the focal length?\u003cbr data-start=\"561\" data-end=\"564\"\u003e\u003cstrong data-start=\"566\" data-end=\"572\"\u003eA:\u003c\/strong\u003e 28mm, perfect for wide-angle shots.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"611\" data-end=\"723\"\u003e\n\u003cp data-start=\"613\" data-end=\"723\"\u003e\u003cstrong data-start=\"613\" data-end=\"619\"\u003eQ:\u003c\/strong\u003e Does it support low-light photography?\u003cbr data-start=\"658\" data-end=\"661\"\u003e\u003cstrong data-start=\"663\" data-end=\"669\"\u003eA:\u003c\/strong\u003e Yes, f\/1.4 aperture excels in low-light conditions.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"724\" data-end=\"850\"\u003e\n\u003cp data-start=\"726\" data-end=\"850\"\u003e\u003cstrong data-start=\"726\" data-end=\"732\"\u003eQ:\u003c\/strong\u003e Is it suitable for professional use?\u003cbr data-start=\"769\" data-end=\"772\"\u003e\u003cstrong data-start=\"774\" data-end=\"780\"\u003eA:\u003c\/strong\u003e Absolutely, designed for professional and enthusiast photographers.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5 data-start=\"852\" data-end=\"876\"\u003eMaintenance Tips\u003c\/h5\u003e\n\u003cul data-start=\"877\" data-end=\"1175\"\u003e\n\u003cli data-start=\"877\" data-end=\"943\"\u003e\n\u003cp data-start=\"879\" data-end=\"943\"\u003eClean lens surfaces with a microfiber cloth and lens solution.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"944\" data-end=\"1018\"\u003e\n\u003cp data-start=\"946\" data-end=\"1018\"\u003eUse front and rear caps when not in use to prevent dust and scratches.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1019\" data-end=\"1079\"\u003e\n\u003cp data-start=\"1021\" data-end=\"1079\"\u003eStore in a cool, dry place to maintain optical coatings.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1080\" data-end=\"1116\"\u003e\n\u003cp data-start=\"1082\" data-end=\"1116\"\u003eAvoid impacts or harsh handling.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1117\" data-end=\"1175\"\u003e\n\u003cp data-start=\"1119\" data-end=\"1175\"\u003eCheck focus ring and aperture smoothness periodically\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Leica","offers":[{"title":"Default Title","offer_id":54162613993756,"sku":"845","price":8555.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0933\/0622\/4924\/files\/845-00_17.jpg?v=1780150501","url":"https:\/\/www.mybackyardzone.com\/products\/leica-28mm-f1-4-summilux-m-asph","provider":"Backup Power Made Simple","version":"1.0","type":"link"}
