Descripción

NO existe mayor diferencia en resultados y ambición que entre el Noctilux-M 50 mm f:1 diseñado por Walter Mandler y el Noctilux-M 50 mm f:0,95 ASPH creado por Karbe. Ambos diseños están separados por más de 30 años.

Cuando Mandler diseñó su versión del Noctilux tenía que trabajar bajo el dictado de la frugalidad. Leitz luchaba para sobrevivir en una fusipon con Wild Heerbrugg y el negocio fotográfico no recibía mucha atención. La cámara telemétrica podía beneficiarse de una oleada de entusiasmo con un objetivo de reperesentación, y el prestigio de Leitz como fabricante de equipo fotográfico de alta calidad estaba desvaneciéndose. Mandler tenía acceso unicamente a herramientas y métodos convencionales, pero podía utilizar un nuevo vidrio con un índice de refracción especialemente alto que había sido desarrollado en el laboratorio de vidrios de Leitz


In 2008 Leica had risen from the ashes after a near-bankruptcy and with a substantial cash injection had the means to innovate vigorously. Under the aggressive leadership of the then acting CEO Steven Lee and enabled by modern high-tech (CNC) production technology and sophisticated logistics lens designs were possible with very narrow tolerances for enhanced image quality.

The optical design department under the leadership of Mr. Karbe created new glass types to be melted by Schott, added floating elements with minute tolerances, juggled with anomalous dispersion numbers and other exotic characteristics of optical glass, installed new equipment to grind the glass surfaces into accurate shapes and to center the lens elements with an accuracy in the nanometer range. The result? The first super-fast standard lens that is at least as good as the Summilux-M 1:1.4/50 mm ASPH, the reigning champion of high-speed lenses of 50 mm focal length. With 700 grams of weight, dimensions of 75 x 73 mm (length and diameter) and a heart breaking price tag, the new Noctilux demonstrates the newfound confidence of the Leica Company.

The choice for an aperture of 1:0.95 is quite daring, not only because the 11% increase in pupil diameter does pose challenges for the aberration control. Contrast at maximum aperture is high with excellent definition of fine detail. Gone is the focus shift, the presence of coma has been visibly reduced and stopped down the lens equals and even surpasses (slightly!) the performance of the Summilux-M 1:1.4/50mm ASPH. There is some occurrence of chromatic aberration that is almost impossible to avoid in high-speed lenses.

Light fall-off is still substantial, but less important with current digital post processing. With sensitive fingers you could just notice a hint of resistance. To hold the dimensions to acceptable sizes the distance ring is quite thin-walled and if you press too hard with your fingers on the mount and perceptible stiffening is the result.

Overall the new Noctilux is a superb performer, but with a price tag and size/weight that put it in a category of its own. It is related to the new Apo-Summicron-M 1:2/50mm ASPH as a Bugatti Veyron to a Porsche. The price relation with the Summulux-M 1.4/50 mm ASPH has changed dramatically: in 2009 the Noctilux-M 1:0.95/50 mm ASPH has a price tag of E 7995 and the Summilux-M 1:1.4/50 mm ASPH costs E 2750 which amounts to a difference of 290%! The very elaborate manufacture of the aspherical elements and the choice of exclusive glass types partly explain the price. AS an aside one might note that the Mandler design was inspired by cost reduction as much as possible.
