Product Description
The optical structure of the LEICA SUMMILUX-M 50mm f/1.4 ASPH. consists of eight lenses in 5 groups. Glass with anomalous partial dispersion (elements 2/3) was used to ensure correct color rendition. Lens element 2 is made of a fluorite-type glass while lens element 3 is made from glass originating from the former Leitz glass laboratory. Lens element 4 has an aspherical surface. Lens elements 1, 6 and 7 are made of glass with a very high refractive index to minimize monochromatic aberrations. In all every innovation currently available in lens technology - aspherical lenses, glass with anomalous partial dispersion (APO), glass with a high refraction index and a floating element - has been combined to create a lens that will set new imaging standards. This is the first Leica M lens with a specifically patented 'floating element' used to maintain imaging performance at a very high level even in close-focus ranges down to 0.7m. During focusing, the rear most optical component (elements 7/8) moves relative to the rest of the optical system and produces brilliant image quality in near focus ranges. To maximize the benefits of the 'floating element' an extremely precise adjusting mechanism has also been utilized that had to fit into the restricted space inside this compact M-lens At full aperture, the LEICA SUMMILUX-M 50mm f/1.4 ASPH. offers high contrast rendering even for the finest structures. This performance can only be raised

Probably the shortest review I've ever written simply because the lens is incredible and you have to feel it in hand and use it to realize the difference and also because the time I spend on the review I would rather put into playing with the lens!So, this is a Leica and you realize that the minute you hold the lens. The build quality is second to none! I opted for the silver since the vast knowledge of Leica info online affords one the experience of many and from what I have discerned the silver lens is brass, the black aluminum. Brass is a much more substantial metal and weathers use well while from my own experience in dealing with aluminum for various projects I have come to the conclusion that aluminum is not as robust or forgiving as brass. As for the color difference and use in street photography, I don't see anyone really noticing a difference considering the size of the lens and any camera it will fit onto.The IQ is impressive. So much better than any Canon or Nikon I have used in the past and the manual focus is smooth and responsive; a pleasure to use and only enhanced by the added focusing tab. Barely noticeable is a slight softness in the edges that you have to really zoom in to notice and essentially sharp at f1.4 which is the reason why one purchases a $4k lens in the first place.So in keeping this short...if you can afford the lens I suggest you buy it. Rumor and history has it that the prices go up nearly each year. The new M is on its way and lens supply is sure to dry up. Best to make the purchase now and have the lens rather than be on the waiting lists that will surely be popping up in the next few weeks.

Still use my Summilux which my Dad bought while in Germany in 1960 along with the Leica M3. 53 years and still going strong.

It renders a perfectly sharp image even when fully opened. Silver color matches perfectly with my steel grey Leica M9.
