Lens Summary\u003c\/h2\u003e\u003cp\u003eThe Leica Summilux-M 21 f\/1.4 ASPH. Lens is a fast ultra wide angle \u003ca href=\"https:\/\/www.parkcameras.com\/lenses\/leica-m-mount\/\"\u003eM lens for rangefinders\u003c\/a\u003e which offers excellent performance over the entire image field. Image quality is sharp and concise, even when stopping down to the fastest aperture in the close-up range thanks to a ‘floating element’. Stopping down to f\/2.8 leads to absolutely outstanding image quality, ensuring the lens resolves high resolution detail on any of the latest high resolution \u003ca href=\"https:\/\/www.parkcameras.com\/cameras\/leica-m-rangefinders\/\"\u003eRangefinder cameras\u003c\/a\u003e. In comparison to the Elmarit lens of the same focal 21mm length, the Summilux-M 21 rendition is slightly more uniform across the image field.\u003c\/p\u003e\u003cp\u003eThe vignetting typical of every optical system is naturally more apparent with a super wide angle lens, particularly a high speed one like this, than on standard lenses or those with a long focal length. At full stop with the 35mm format, its maximum - i.e. in the corners of the image - is around 3.2 aperture stops or, with the Leica M8 models and their slightly smaller format, around 1.9 aperture stops. Stopping down to 2.8 visibly reduces this light fall-off towards the image edges to 1.7 or 0.8 aperture stops. Stopping down further does not bring any noticeable additional reduction, as all that remains is essentially the natural vignetting.\u003c\/p\u003e\u003cp\u003eThe maximum distortion of the lens is 2.3%,which in practical terms is negligible for the majority of photographic applications. A total of ten lens elements are used to achieve this exceptional performance. To correct colour aberrations, five of these are made of glass types with anomalous colour dispersion(partial dispersion), while a further two have aspherical surfaces. To maintain performance in the close-up range, one group towards the rear of the optical system is a ’floating element’ that moves independently of the rest of the mechanism.\u003c\/p\u003e\u003cp\u003eThe five anomalous partial dispersion elements serve to correct vignetting and distortion which is all but eliminated at aperture of f\/2.8 through to the maximum f\/16 aperture. The floating element retains the lenses’ high resolution, even in the close-up range. A patented, rectangular lens hood fits Series VIII filters.\u003c\/p\u003e\n\u003ch3\u003eWhat's in the Box\u003c\/h3\u003e\n\n\u003chr\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable
