Lens\u003c\/h3\u003e\n\u003cp\u003eLeica Camera is pleased to introduce the Leica \u003cstrong\u003eSummilux-M 28mm f\/1.4 ASPH,\u003c\/strong\u003e the first Leica M-lens to combine an initial aperture of f\/1.4 with the popular 28mm wide-angle focal length. 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\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.\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eHighlights:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDiagonal picture angle: 75°\u003c\/li\u003e\n\u003cli\u003eWorking range: 0.7 m to infinity\u003c\/li\u003e\n\u003cli\u003eBiggest scale: 1: 21.9\u003c\/li\u003e\n\u003cli\u003eNumber of lenses\/groups: 10\/7\u003c\/li\u003e\n\u003cli\u003eLens hood: can be screwed on\u003c\/li\u003e\n\u003cli\u003eFilter\/filter thread: E49\u003c\/li\u003e\n\u003cli\u003eMade in Germany\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ef\/1.4 ultra-fast aperture for high-speed wide-angle photography\u003c\/li\u003e\n\u003cli\u003e28mm wide-angle focal length with 75° diagonal view angle (65° horizontal, 46° vertical)\u003c\/li\u003e\n\u003cli\u003eFirst Leica M-lens combining f\/1.4 aperture with 28mm focal length\u003c\/li\u003e\n\u003cli\u003eExcellent image performance across entire image field at full aperture\u003c\/li\u003e\n\u003cli\u003eFloating element maintains high performance in close-up range\u003c\/li\u003e\n\u003cli\u003eExceptional contrast matching or exceeding Summilux-M 35mm f\/1.4 ASPH.\u003c\/li\u003e\n\u003cli\u003e10 lens elements in 7 groups with 1 aspherical surface\u003c\/li\u003e\n\u003cli\u003eSeven lens elements with anomalous color dispersion (partial dispersion)\u003c\/li\u003e\n\u003cli\u003eExtremely low distortion at maximum 1.1% for a wide-angle lens\u003c\/li\u003e\n\u003cli\u003eMaximum vignetting of 3.4 stops at full aperture in corners\u003c\/li\u003e\n\u003cli\u003eVignetting reduces to 1.8 stops at f\/5.6 and 0.8 stops at f\/8\u003c\/li\u003e\n\u003cli\u003eClose focus distance of 0.7 meters\u003c\/li\u003e\n\u003cli\u003eClick-stop diaphragm with half-increment lock settings\u003c\/li\u003e\n\u003cli\u003eSmallest aperture of f\/16\u003c\/li\u003e\n\u003cli\u003eLeica M bayonet\u003c\/li\u003e\n\u003cli\u003eE49 filter thread\u003c\/li\u003e\n\u003cli\u003eScrew-on lens hood included\u003c\/li\u003e\n\u003cli\u003eUnmistakable visual signature\u003c\/li\u003e\n\u003cli\u003eHigh imaging performance for wide-angle photography\u003c\/li\u003e\n\u003cli\u003eMade in Germany\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCompatible With:\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eCameras\u003c\/strong\u003e:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eM-Mount Cameras\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eFilters\u003c\/strong\u003e:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e49mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eDimensions:\u003c\/h3\u003e\n\u003cp\u003eø: 2.4 x L: 2.6\"\u003c\/p\u003e\n\u003ch3\u003eWeight:\u003c\/h3\u003e\n\u003cp\u003e0.97 lbs\u003c\/p\u003e\n\u003ch3\u003eMaterials:\u003c\/h3\u003e\n\u003cp\u003eMetal\u003c\/p\u003e\n\u003ch3\u003eManufacturer SKU:\u003c\/h3\u003e\n\u003cp\u003e11668\u003c\/p\u003e\n\u003ch3\u003eIn The Box:\u003c\/h3\u003e\n\u003cp\u003eLeica Summilux-M 28mm f\/1.4 ASPH.
