I rememeber when he was doing a talk some years ago about the Noctilux f/0.95. He obviously loves everything about lenses.

What keeps him busy and enthusiastic in his office is funny enough also what can get him out of the office and speak enthusiastically and forget his shyness: They were both released in May 2012 in Berlin, and promoted a new level of resolution in details and sharpness. The Leica M Monochrom 'Henri' with the Leica 50mm APO-Summicron-M ASPH f/2.0 lens. He reminds me of a shy school boy that avoid s eye contact, but then when you ask about the airplane he is holding in his hand, he forgets his shyness and explains enthusiastically all about it. 'Well, I haven't been missing it', he replied with a big laugh and an attitude that overall show the nature of Peter Karbe. When we met in April 2014 in the new canteen in Wetzlar, I told him this was the reason the interview hadn't been published. Unfortunately the sound was so bad (made on the D-Lux 6), I decided to do a written interview and not use the video. When I visited the old Leica Camera AG factory in Solms in Germany in January 2013 I video-recorded a talk I had with legendary lens designer Peter Karbe. The Peter Karbe Interview that almost didn't happen Leica 50mm APO-Summicron LHSA Video Review In this article I will try to define what is so wonderful about it, and I will also give the backstory as to how this lens became reality. He knew it was possible to make it, but unfortunately at the same time he also knew it would be impossible to demand from customers what it would cost. The story of the ridiculously normal looking $8,250 Leica 50mm APO-Summicron-M ASPH f/2.0 lens for the Leica M cameras is the vision of a perfect lens, dreamt of for years by the master lens designer Peter Karbe. I asked myself 'how is it the best?' and when I came up short, I interviewed the designer of the lens himself, Mr. This means that the Summicron-SL lenses achieve values that are among the best in the full-frame system segment in terms of speed, precision, and noise emissions.The Leica 50mm APO-Summicron-M ASPH f/2.0 has been labeled РІР‚СљThe best 50mm lens in the worldРІР‚Сњ. Thanks to these, the entire focusing throw can be traveled completely in fractions of a second. In the Summicron-SL lenses, the drive units installed are extremely powerful and robust stepping motors with Dual Syncro DriveРІвЂћСћ. This requires a dynamic drive system without any play. In this procedure, the focusing lenses must be moved rapidly backwards and forwards in accordance with the speed specifications of the contrast AF system.

Several contrast measurements at various focusing positions must be made before the correct direction of motion for focusing can be determined and followed by precise focusing. In addition to space limitations, the choice of the drive motors is also determined by the AF principle used for focusing. This system, comprising two particularly light focusing lenses, allows the construction of particularly small and compact drive systems. Specialists from the areas of optical and mechanical engineering and electronics worked together in an interdisciplinary team on the development of a unique lens concept based on double internal focusing. In order to preserve the compact dimensions of the lenses, the integration of these components must follow an integral approach. These are limited only by the mass of the lens elements moved when focusing, the travel from infinity to the closest focusing distance and, of course, the amount of space available. They thank their outstanding AF performance figures to the autofocus drive unit they share. The AF system of the Summicron-SL lenses is fast, precise, and almost silent.
