With its compact body - only marginally longer and slightly heavier than the Summicron-M 1:2\/50 mm, and with an almost identical diameter, it provides visibly higher image quality.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eOn the Leica APO Summicron-M 1:2\/50 mm ASPH. the exceptional correction enables all aberrations to be reduced to a minimum level that is negligible in digital photography. Its key features include excellent contrast rendition, all the way to the corners of the image, even with a fully open aperture. The use of a \"floating element\" ensures that this is retained, even for close-up shots.\u003c\/p\u003e\n\u003cp\u003eVignetting is limited to a maximum - i.e. in the corners of the image - of just 2 stops at full aperture in 35 mm format, or around 1 on the Leica M8 models. Stopping down to 2.8 visibly reduces this light deterioration towards the edge of the image, with practically only the natural vignetting remaining.\u003c\/p\u003e\n\u003cp\u003eDistortion is very low at a maximum of just 0.4 % (pincushion), which is practically imperceptible. A total of eight lens elements are used to achieve this exceptional performance.\u003c\/p\u003e\n\u003cp\u003eTo realize the apochromatic correction (resulting in a common focusing plane for three light wavelengths), three are made of glass types with high anomalous partial color dispersion, while two of the others have a high refractive index. The aspherical surface of the first lens in the rear group helps to reduce spherical aberration and flatten the image field. While the optical construction in front of the aperture is a Gaussian type, the arrangement of the lens elements behind it is similar to that in the Summilux-M 1:1.4\/35 mm ASPH. This group comprises a \"floating element.\u003c\/p\u003e\n\u003ch5 data-start=\"86\" data-end=\"116\"\u003eWhat Our Experts Think\u003c\/h5\u003e\n\u003cul data-start=\"117\" data-end=\"462\"\u003e\n\u003cli data-start=\"117\" data-end=\"205\"\u003e\n\u003cp data-start=\"119\" data-end=\"205\"\u003eFast f\/2 aperture provides excellent low-light performance and smooth, creamy bokeh.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"206\" data-end=\"286\"\u003e\n\u003cp data-start=\"208\" data-end=\"286\"\u003eAPO ASPH optics deliver outstanding sharpness, contrast, and color fidelity.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"287\" data-end=\"371\"\u003e\n\u003cp data-start=\"289\" data-end=\"371\"\u003eClassic 50mm focal length ideal for portraits, street, and everyday photography.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"372\" data-end=\"462\"\u003e\n\u003cp data-start=\"374\" data-end=\"462\"\u003eSleek black finish complements Leica M cameras while offering professional durability.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5 data-start=\"464\" data-end=\"475\"\u003eQ\u0026amp;A\u003c\/h5\u003e\n\u003cul data-start=\"476\" data-end=\"922\"\u003e\n\u003cli data-start=\"476\" data-end=\"597\"\u003e\n\u003cp data-start=\"478\" data-end=\"597\"\u003e\u003cstrong data-start=\"478\" data-end=\"484\"\u003eQ:\u003c\/strong\u003e Is this lens compatible with Leica M cameras?\u003cbr data-start=\"530\" data-end=\"533\"\u003e\u003cstrong data-start=\"535\" data-end=\"541\"\u003eA:\u003c\/strong\u003e Yes, fully compatible with all Leica M-mount cameras.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"598\" data-end=\"705\"\u003e\n\u003cp data-start=\"600\" data-end=\"705\"\u003e\u003cstrong data-start=\"600\" data-end=\"606\"\u003eQ:\u003c\/strong\u003e What is the focal length?\u003cbr data-start=\"632\" data-end=\"635\"\u003e\u003cstrong data-start=\"637\" data-end=\"643\"\u003eA:\u003c\/strong\u003e 50mm, perfect for portrait and general-purpose photography.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"706\" data-end=\"800\"\u003e\n\u003cp data-start=\"708\" data-end=\"800\"\u003e\u003cstrong data-start=\"708\" data-end=\"714\"\u003eQ:\u003c\/strong\u003e How does it perform in low light?\u003cbr data-start=\"748\" data-end=\"751\"\u003e\u003cstrong data-start=\"753\" data-end=\"759\"\u003eA:\u003c\/strong\u003e Excellent, thanks to the f\/2 aperture.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"801\" data-end=\"922\"\u003e\n\u003cp data-start=\"803\" data-end=\"922\"\u003e\u003cstrong data-start=\"803\" data-end=\"809\"\u003eQ:\u003c\/strong\u003e Suitable for professional use?\u003cbr data-start=\"840\" data-end=\"843\"\u003e\u003cstrong data-start=\"845\" data-end=\"851\"\u003eA:\u003c\/strong\u003e Absolutely, designed for professional photographers and enthusiasts.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5 data-start=\"924\" data-end=\"948\"\u003eMaintenance Tips\u003c\/h5\u003e\n\u003cul data-start=\"949\" data-end=\"1268\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e\n\u003cli data-start=\"949\" data-end=\"1017\"\u003e\n\u003cp data-start=\"951\" data-end=\"1017\"\u003eClean lens glass with a microfiber cloth and lens-safe solution.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1018\" data-end=\"1092\"\u003e\n\u003cp data-start=\"1020\" data-end=\"1092\"\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=\"1093\" data-end=\"1158\"\u003e\n\u003cp data-start=\"1095\" data-end=\"1158\"\u003eStore in a dry, cool environment to protect optical coatings.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1159\" data-end=\"1195\"\u003e\n\u003cp data-start=\"1161\" data-end=\"1195\"\u003eAvoid impacts or rough handling.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1196\" data-end=\"1268\" data-is-last-node=\"\"\u003e\n\u003cp data-start=\"1198\" data-end=\"1268\" data-is-last-node=\"\"\u003ePeriodically check focus and aperture mechanisms for smooth operation.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Leica","offers":[{"title":"Default Title","offer_id":45364697366588,"sku":"46793","price":7458.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/6151\/5324\/files\/46792-00_21.jpg?v=1778504369","url":"https:\/\/e-powergo.com\/products\/leica-m-50mm-f2-0-apo-asph","provider":"Set Up Your Ultimate Retreat","version":"1.0","type":"link"}
