A sensor monitors the status of the magnetic field and sends the data to the main processor. The drive then shifts the lens to the corresponding focusing position on the basis of the angle of rotation and the rotational speed.\u003cbr\u003eThe construction of the MF-ring guarantees reliable sealing against dust and water spray, provides protection against impacts and other mechanical stresses, and prevents focusing inaccuracies as a consequence of temperature fluctuations. Even after years of use, the MF-ring of a SL-Summicron lens impresses with a smooth action without play and homogeneous focusing.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eImpressive\u003cbr\u003edown to the smallest detail\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003eThe consistently compact dimensions, low weight, and the excellent grip and feel of the SL-Summicron lenses are particularly impressive when shooting. Thanks to the almost identical design of the Summicron-SL lenses, feeling for the MF ring is unnecessary after switching lenses and the center of gravity remains largely the same. This means that the camera always lies perfectly in the hand and makes working from a tripod much easier. \u003cbr\u003e\u003cb\u003e\u003cfont size=\"4\"\u003e\u003cbr\u003e\u003c\/font\u003e\u003c\/b\u003e\u003cbr\u003e\u003cb\u003e\u003cfont size=\"4\"\u003e\u003cbr\u003e\u003c\/font\u003e\u003c\/b\u003e\u003cbr\u003e\u003cb\u003e\u003cfont size=\"4\"\u003eProduct Specifications:\u003c\/font\u003e\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eOrder number\u003c\/b\u003e 11 179\u003cbr\u003e\u003cbr\u003e\u003cb\u003eField angle \u003c\/b\u003e(diagonal, horizontal, vertical) 27.3° \/ 22.9° \/ 15.4°\u003cbr\u003e\u003cbr\u003e\u003cb\u003e\u003cfont size=\"4\"\u003eOptical design\u003c\/font\u003e\u003c\/b\u003e\u003cbr\u003e\u003cb\u003eNumber of lenses\/groups\u003c\/b\u003e 11\/9\u003cbr\u003e\u003cb\u003eNumber of aspherical lenses\u003c\/b\u003e 1\u003cbr\u003e\u003cb\u003eEntrance pupil position \u003c\/b\u003e 22.9 mm\u003cbr\u003e\u003cb\u003e\u003cfont size=\"4\"\u003e\u003cbr\u003e\u003c\/font\u003e\u003c\/b\u003e\u003cbr\u003e\u003cb\u003e\u003cfont size=\"4\"\u003eDistance setting\u003c\/font\u003e\u003c\/b\u003e\u003cbr\u003e\u003cb\u003eWorking range\u003c\/b\u003e 0.6 m to infinity\u003cbr\u003e\u003cb\u003eSmallest object field\u003c\/b\u003e 120 x 180 mm\u003cbr\u003e\u003cb\u003eLargest reproduction ratio \u003c\/b\u003e1:5\u003cbr\u003e\u003cb\u003e\u003cfont size=\"4\"\u003e\u003cbr\u003e\u003c\/font\u003e\u003c\/b\u003e\u003cbr\u003e\u003cb\u003e\u003cfont size=\"4\"\u003eAperture\u003c\/font\u003e\u003c\/b\u003e\u003cbr\u003e\u003cb\u003eSetting\/function Electronically \u003c\/b\u003econtrolled aperture, set using turn\/push wheel on camera, including half and third values\u003cbr\u003e\u003cb\u003eAperture\u003c\/b\u003e setting range 2-22\u003cbr\u003e\u003cb\u003eLowest value\u003c\/b\u003e 22\u003cbr\u003e\u003cbr\u003e\u003cb\u003eBayonet\/sensor format \u003c\/b\u003eL-Mount, full-frame 35mm format\u003cbr\u003e\u003cbr\u003e\u003cb\u003eFilter mount\u003c\/b\u003e E67\u003cbr\u003e\u003cbr\u003e\u003cb\u003e\u003cfont size=\"4\"\u003eDimensions and weight\u003c\/font\u003e\u003c\/b\u003e\u003cbr\u003e\u003cb\u003eLength to bayonet mount\u003c\/b\u003e 102 mm\u003cbr\u003e\u003cb\u003eLargest diameter\u003c\/b\u003e 73mm\u003cbr\u003e\u003cb\u003eWeight\u003c\/b\u003e 700 g","brand":"Leica","offers":[{"title":"Default Title","offer_id":52239408890219,"sku":"72254","price":6200.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/3256\/2235\/products\/72254-05.jpg?v=1678465938"},{"product_id":"leica-sl-50mm-f2-apo-summicron-asph","title":"Leica SL 50mm f2 APO-Summicron Asph.","description":"The optical formula for the APO-Summicron-SL 50 mm f\/2 ASPH. achieves such incredible image quality through its design of 12 extremely complex lens elements, 3 of which are aspherical, arranged in 10 groups.
