Leica 24 mm Wide-Angle ASPH Rangefinder Lenses Product Info

Leica Elmar-M 24mm f/3.8 ASPH.Lens is an extremely compact lens, especially for such a wide angle, which also offers outstanding imaging performance. Even with atimage full stop, this Leica Camera Accessory delivers uniformly excellent reproduction quality over the entire image field, only deteriorating slightly towards the edges in the close-up range. This performance can only be improved slightly by stopping down, which means that you can take photographs with at full stop without concerns, unless your compositional ideas call for a greater depth of field that can only be achieved with smaller apertures. The vignetting characteristic of every optical system is naturally more pronounced on a super wide angle lens than on normal and long focal length lenses. With the diaphragm completely open, it is a maximum - i.e. in the corners of the image - of around 1.9 stops for the 35mm format, or around 1.1 stops on Leica M8 models with their slightly smaller format. Stopping down to 5.6 visibly reduces this light falloff at the image edges - to 1.4 and 0.8 stops respectively. Stopping down further does not bring about any notable reduction since essentially only the natural vignetting remains. The lens' maximum distortion is around 1% and therefore hardly perceptible.The retrofocus-like construction is made up of a total of eight lens elements and the use of an aspherical surface and glass types with anomalous color dispersion (partial dispersion) make a crucial contribution towards restricting aberrations to an absolute minimum.

Leica Elmarit M 24mm / f2.8 ASPH. Rangefinder Lens is contrast and detail rendition even at full aperture set new standards among wide-angle lenses. Stopping down by just 1 to 1.5 apertures delivers maximum optical performance across the entire image field.The high levels of brilliance and plasticity are retained even in close-up photography. This lens by Leica is ideal for photojournalism assignments and architectural shots. The 24 mm focal length means that converging verticals, such as those encountered when shooting buildings, are easy to master with this lens without having to work from too great a distance. Though its focal length is only 3 mm longer than that of a 21 mm lens, the 24mm yields surprisingly natural perspectives with no indication that a super-wide-angle lens has been used.

The very high-speed and compact Leica Summilux-M 24 mm f/1.4 ASPH. gives photo- journalists a new tool for their work. This lens by Leica is ideal for available light photography. Like the 21mm f/1.4, this camera accessory by Leica consists of ten lenses in eight groups. Until the advent of state-of-the-art blank-press methods for aspherical lenses, it was not possible to create these new Summilux-M lenses. Hand assembled in Solms Germany, this meticulous craftsmanship also ensures long term reliability even in challenging conditions. The correction of colour imperfections requires great deal of effort. and to that end this 24mm lens incorporates five separate lenses with anomalous partial dispersion. As a result, vignetting and distortion, the parameters traditionally difficult to control in fast wide-angle lenses, are corrected so well that they are hardly noticeable in practice. Even at an f-stop of 2.8, in effect, only natural vignetting is present. Patented rectangular lens hoods fit Series VII filters.
