At the decisive moment, its almost silent and simultaneously precise autofocus gives photographers more time to concentrate fully on the creative aspects of their subject, the person in front of their camera. Like all Leica SL-Lenses, the APO-Summicron-SL 1:2\/90 ASPH. is perfectly matched to the modern SL-System and is constructed for a long working life under professional shooting conditions.\u003cbr\u003e\nFeatures\u003cbr\u003e\nAF System with Dual Syncro Drive - From zero to sharp in no time\u003cbr\u003e\nThe AF system of the Summicron-SL lenses is fast, precise, and almost silent. They thank their outstanding AF performance figures to the autofocus drive unit they share. These are limited only by the mass of the lens elements moved when focusing, the travel from infinity to the closest focusing distance and, of course, the amount of space available. In order to preserve the compact dimensions of the lenses, the integration of these components must follow an integral approach.\u003cbr\u003e\nHigher Contrast - For greater perceived depth\u003cbr\u003e\nWith an initial aperture of f\/2, the SL-Summicron lenses are significantly more compact than faster lenses, but still allow photographers to work with similar depth of field. The reason for this is contrast: the zone of highest contrast is perceived by viewers as being sharp, while zones with lower contrast are regarded as being unsharp.\u003cbr\u003e\nOptically and Mechanically - A new standard\u003cbr\u003e\nIn the construction of the Summicron-SL lenses, particular attention has been paid to the prevention of stray light and reflections. The optimization of the optical and mechanical design was carried out in elaborate simulations before the construction of the first prototype lenses. Unavoidable reflections are reduced to the best possible level by high-quality coating of lens surfaces.\u003cbr\u003e\nComplex Electronics - For uncomplicated handling\u003cbr\u003e\nThe focusing and aperture setting functions of a SL-Summicron lens are based on a multitude of control systems and mathematical operations. The demands on the electronics are particularly high in the case of the double focusing system.\u003cbr\u003e\nManual Focusing - A new experience\u003cbr\u003e\nSL-Summicron Lenses feature a totally new manual focusing ring construction concept. In this concept, a ring magnet with alternating north-south magnetization is embedded in the manual focusing ring. The magnetic field changes its polarity when the ring is turned. 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\u003e\nImpressive - Down to the smallest detail\u003cbr\u003e\nThe 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\nConstructional Details\u003cbr\u003e\nThe optical system of the APO-Summicron-SL 90 f\/2 ASPH. is comprised of 11 elements, one of which has an aspherical surface. A very high proportion of these elements is manufactured from specially formulated, high-quality glass types for the correction of chromatic aberration. Their particular optical property, so-called anomalous partial dispersion, enables compensation for chromatic aberrations resulting from the other glasses in the optical system. As a result of this, even highlights in images remain almost completely free of color fringing.\u003cbr\u003e\nRead More\u003cbr\u003e\nCalifornia customers\u003cbr\u003e\nProposition 65 WARNING\u003cbr\u003e\nWARNING: Cancer and Reproductive Harm\u003c\/p\u003e\n\n\n\u003cp\u003eSpecifications\u003cbr\u003e\nGeneral\u003cbr\u003e\nColor\u003cbr\u003e\nBlack\u003cbr\u003e\nCompatibility\u003cbr\u003e\nLeica\u003cbr\u003e\nType\u003cbr\u003e\nMedium Telephoto\u003cbr\u003e\nMacro\u003cbr\u003e\nNo\u003cbr\u003e\nMaximum Reproduction Ratio\u003cbr\u003e\n1:05\u003cbr\u003e\nFilter Size\u003cbr\u003e\n67mm\u003cbr\u003e\nLens Elements\u003cbr\u003e\n11\u003cbr\u003e\nLens Format Coverage\u003cbr\u003e\nFull Frame\u003cbr\u003e\nLens Groups\u003cbr\u003e\n9\u003cbr\u003e\nFixed Focal Length\u003cbr\u003e\n90mm\u003cbr\u003e\nMaximum Focal Length\u003cbr\u003e\n90mm\u003cbr\u003e\nMinimum Focal Length\u003cbr\u003e\n90mm\u003cbr\u003e\nFocal Length (35mm Film Equivalent)\u003cbr\u003e\n135mm\u003cbr\u003e\nAspherical Elements\u003cbr\u003e\n1\u003cbr\u003e\nMaximum Aperture\u003cbr\u003e\nf\/ 2\u003cbr\u003e\nMinimum Aperture\u003cbr\u003e\nf\/ 22\u003cbr\u003e\nMinimum Focus Distance\u003cbr\u003e\n1.97' \/ 60cm\u003cbr\u003e\nMaximum Diameter\u003cbr\u003e\n73mm\u003cbr\u003e\nLens Mount Compatibility\u003cbr\u003e\nLeica L\u003cbr\u003e\nAngle of View\u003cbr\u003e\n27.3°\/ 22.9°\/ 15.4°\u003cbr\u003e\nFocus Type\u003cbr\u003e\nAuto\/Manual\u003cbr\u003e\nLens Construction\u003cbr\u003e\n11 elements in 9 groups\u003cbr\u003e\nDust\/Water Resistant\u003cbr\u003e\nYes\u003cbr\u003e\nIn the Box\u003cbr\u003e\n90mm APO-Summicron-SL f\/2 ASPH Lens, E67 Lens Cap, Rear Lens Cap L, Lens Hood, Lens Bag\u003cbr\u003e\nApproximate Dimensions\u003cbr\u003e\nLength (in)\u003cbr\u003e\n4.01\u003cbr\u003e\nPackage Size HxWxL (in)\u003cbr\u003e\n3 x 5 x 8\u003cbr\u003e\nWarranty Information\u003cbr\u003e\nLabor Warranty\u003cbr\u003e\n2 Years Limited\u003cbr\u003e\nParts Warranty\u003cbr\u003e\n2 Years Limited\u003cbr\u003e\nApproximate Weight\u003cbr\u003e\nUnit Weight (lbs.)\u003cbr\u003e\n1.54\u003cbr\u003e\nPackage Weight (lbs)\u003cbr\u003e\n2\u003c\/p\u003e","brand":"Leica","offers":[{"title":"Default Title","offer_id":68007932952725,"sku":"11179","price":3100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/3808\/9877\/files\/1-11179.jpg?v=1792507677","url":"https:\/\/noosclub.shop\/nl\/products\/leica-apo-summicron-sl-90mm-f-2-asph-lens-11179-152657","provider":"ThursdayShoes","version":"1.0","type":"link"}
