The well-balanced package makes for a perfect normal lens in an outstanding selection in conditions of all criteria, which includes photo quality, size, speed, price and weight.

Positioned in the class of fast normal lenses, this handy multipurpose lens comes with a world-wide status of premier optical performance. There's outstanding image quality even while at the closest focus distances. It is manufactured in anodized black finish plus a chrome silver finish. An integrated slide out lens hood is included.

Leica lens new updated "6-bit" coding

This Leica lens features the new updated "6-bit" coding, that allows the M digital camera to optically read this information and then identify the lens being mounted. Optionally the M camera can then apply a software based "last stage" vignetting adjustment (for images captured in RAW, the lens mounted is simply recorded, with no changes made).  Read more.

Includes "6-bit code" which allows the digital M8 camera to identify which lens is being used, and also to store this information in image metadata

M Mount AdaptersLeica Four Thirds Adapter
The Leica M mount was introduced in 1954 at the same time as the Leica M3. It's been the mount of choice on every Leica M series thru the present day Leica M7 film camera and Leica M9 digital camera and Lenses.

The M Mount was also the mount used for Minolta's CLE rangefinder, on the Konica Hexar RF, on the later versions of the Voigtlander Bessa family and Lenses, the mount for the Rollei 35RF, also quite recently on the newest Zeiss Ikon Rangefinder and Lenses..

Benefits of Lens adapters is versatility, and saving money with the continued use of the preferred lenses you already own.

Drawbacks of lens adapters is the inconvenience, no electronic connection between the adapted lens and your camera body A couple of factors are necessary for a lens adapter to work properly. First, the camera body "lens registration" space or the expanse between the mount of the lens to the sensor or film surface. Two, the "throat size" of the mount or the mount diameter. An adapter flanked by the body of the camera and a lens from different brands, this registration distance of the adapted lens must be larger than the registration distance on the body; plus the lenses throat-size must be less than the throat size on the body mount. M lenses can be adapted to Canon EOS, Nikon, Micro Four Thirds, and Sony Nex Cameras.

If you still use a 50mm lens, this is may be the best ever, September 21, 2005

By Dom Miliano (Denville, NJ USA)

Years ago, every 35mm camera was offered with a "normal" or 50mm lens. This focal length closely matches the diagonal of the 35mm film plane and was considered the best compromise for general photography. Not too short, not too long - just right.

When you consider that many of the world's greatest photographs have been taken with a 50mm (and many of them on Leicas) you can see why this lens remains in the line. Another reason it's still being made and used by pros and serious fine art folks is that this lens is superb.

I remember reading that Leica lens MTF formulas tend to favor contrast. Other brand lens formulas (no slight intended here) seem to lean more toward edge sharpness and I can't explain the science any more or why that's important. I could when I taught photography but that was years ago. Anyway, when I look at a slide under a good loupe made with a Japanese lens, it looks like a sharp picture of the thing. The same shot taken with a Leica lens tends to look like the real thing - dare I say, almost alive.

My 50mm is a joy to use. While I do not favor photo contests, I do enter them on occasion. Of the last 4 prizes I have won, 3 were taken with Leicas and 2 were taken with my 50mm. It's really a great, sharp, contrasty lens. I think that it makes me a better photographer - I become more involved or creative or serious. I can't figure it out. All I know is that I like what I see and for me, that seems to be enough.

As I mentioned in my f:2.0, 35mm Summicron review, Leica build quality is still as good as it gets. It's solid, smooth and probably will out live me. Assuming that film is still available when I'm older and grayer, I plan on using it for many more years. I use it on a beat up M4 and a Minolta hand held meter (a really good light meter). Sometimes I just load the camera up with Velvia 50 and shoot colors or blue sky and clouds just to see the colors pop on the light table. No, I don't sing the score from "Hair"...

I feel sorry for all of the digital photographers who will never experience the joy of seeing a fine grain slide shot with a Leica lens. Sigh!

Non-Leica people will be shocked by the high price. Long time Leica users will understand what kind of effort goes into each lens and know why it's not a few hundred bucks. Is this lens worth the price? Obviously, I think so, maybe you will too.
