The Leica Summilux-M 28mm f/1.4 ASPH. rounds off the range of high-speed M wide angle focal lengths. It offers exce

lent 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 outperforms it. The 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, around 2 stops on Leica M8 models with their slightly smaller format. 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 maximum

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 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.

Summary: The Leica Summilux-M 28mm f/1.4 ASPH. offers maximum image performance with a focal length / speed

combination previously unavailable in the M system. This extends the composition options of M photography, particulaly

for available light shots, but also thanks to a previously unattainable reduction in the depth of field combined with large

field angles.
