The previous sentence is continued... It's better to ask everyone to eat a lozenge of sugar!
Speaking of Ernst Leitz Wetzlar, many people may not even know this brand.
But if you tell it that it is Leitz, the parent company of the famous Leica Leica, you should suddenly realize it!
However, people familiar with the game know that Leica's cameras and lenses are quite elegant and expensive. I can't afford to use this kind of poverty, so I have to find new ways to find some particularly unpopular shots.
Those who have seen this lens will exclaim, so small is the lens? !
Really, and from the logo on the special adapter tube that comes with the lens, the structure of Mikro-Summar is used. Summar was the early Marking structure of Leica, and Summitar and the most prestigious Summicron were developed one after another. So the common specification is 50mm/f2, and there are 24mm/f2 “geeks†because this is for RMS lens for Leica Microscopes.

The information in the small card we refer to see it, 24mm/f2 that really is very rare, found the entire EBAY did not find.
The RMS lens uses a 4/5" X 1/36" thread mount and is converted to a standard L39 mount via an adapter ring for use with the Leica M Series rangefinder camera for macro photography.
It is because of this special background that there are not many types of lenses that can be found on the market, and the price is much more expensive than ordinary RMS lenses.
The entire lens has an outer diameter of only 25mm, the middle lens is only about 5mm, and the height is about 2/3 coins of 1 yuan. Although the lens does not have a focusing mechanism, the opening and closing of the aperture can be controlled by rotating the front end lens body. From the maximum F2 to the minimum F16, the rotation angle between each stop is not equal.
In the beginning, I stuck the lens directly on a piece of cut PVC film and stuck it in the rear of the E bayonet and the front bay M42. After the installation is complete, the front of the lens is only exposed to a distance of about 1mm and is almost completely embedded inside the focusing barrel.
This is the appearance after the completion of the first transformation. The PVC film has been matted before and after, and a small M42 close-up ring has been installed at the front end of the focusing barrel as a guard and hood.
Thanks to the extremely short bayonet flange spacing of the NEX system, this lens can also achieve infinity coke, but at this time there will be a very obvious dark corner, indicating that the image field of the lens is not enough to cover the APS at infinity -C format.
Due to the use of scenes, the anti-glare capability of this lens is generally good. Therefore, in the sunny outdoors, the saturation and contrast of the picture will be significantly reduced, and it is not occupied compared with the conventional lens. However, the overall color is still very Leica-style. Shooting any weather is like a rainy day. There is a huge difference between Zeiss's full and bright sunny style.
This kind of LOMO style is very much liked, but I have a general interest - although I often can add some vignette in the later period of the picture, which makes the whole picture more focused, but it is still so exaggerated Not too adaptable.
The above picture does not have any post-PS, NEX5's RAW straight out is such a beautiful color, the red petals are very accurate to restore the real object, but the far-end of the bokeh reveals the German unique blue tone.
This is an easy-to-read street-apparel shop window. Even if the aperture is fully open, the entire screen is bright, full, and sharp, and the optical details of the lens are fully revealed because there is no glare.
Afterwards, I specially took a group of rainy days. The drops of water hanging on the plants were shining like a jewel. Especially in the last piece, the details of the white flowers were overly detailed and detailed. I really wanted to say the shortcomings. It was probably a bit behind the bokeh. Not beautiful enough!
However, this lens is really the most powerful macro, after all, is the RMS microscope, the general macro certainly can not be difficult.
This is a photograph taken near the metal security line of 20 RMB. There is no cutting. The original is like this.
Then 100% display, you can not only see the printing ink bulge, even the microscopic texture of the paper can be seen clearly.
Well, in fact, the photo at the beginning was not throat lozenges at all, but the Pacific white granulated sugar shot in super-macro.
