Leica 50mm F/1.4 Summilux-M Titanium E46 + LEICA M6


Leica leica 50mm f/1.4 summilux pre-asph e46 version continues the optical part of leica 50mm f/1.4 summilux e43 version. The e46 version was sold from 1995 until it was replaced by the asph version in 2004. Usually this version of e46 is also called pre-asph.

The difference between E46 and E43

The E46 version has a minimum focusing distance of 0.7 meters, while the E43 version is 1 meter. The gap of 0.3 meters has little effect on street photography, and has a great influence on portrait photography. Because you can get more bokeh at close range. At the same time, 0.7 meters is more practical than 1 meter in a narrow environment.

E43’s hood is external. E46 has a built-in hood.

Image quality

The E46 version is consistent with the E43 style, with large contrast, good sharpness, natural tones, and good bokeh. Some people say that pre-asph is more suitable for color film because of the large contrast. In fact, the contrast of the E43 version is also very large, especially the e43 produced in the 1990s. Contrast is related to the coating. Information shows that Leica has been working hard to enhance the coating, the purpose is to resist glare.

Leica 50mm f/2 Summicron Rigid

Leica 50mm f/2 Summicron Rigid

The Leica summicron 50mm f/2 rigid is the most beautiful lens in the Leica 50mm lens. Leica lenses in the 1950s and 60s are very delicate and beautiful like the Leica m3. There is a clicking sound when turning the aperture ring, crisp and sweet. It’s a pity that this sound can’t be heard in later Leica lenses.

Rigid performance is very good, whether using film or digital.

Later summicron 50mm f/2 DR used the same optical design. DR can shoot at closer distances and is used as a macro lens. But many people prefer rigid because of its simplicity.

If elmar 50mm f/3.5 established the authority of the early Leica, rigid led the new trend of lenses after the 1950s. After decades of rigidity, even today, it is still the top lens. It is the world’s first lens designed using a computer. It is Leica’s first lanthanide glass lens.

Lens glass

In 1949 Leica developed its own lanthanide glass to increase the refractive index and reduce dispersion. This glass is not radioactive. Rigid uses leaded glass, which can increase the refractive index.


The rigid is not sharp, but delicate. Especially the minute details are abundant. And from high light to shadow tone is very natural, which makes many people obsessed.


Glare when facing the light.

rigid version

Narrow focus ring and wider focus ring.

Some are in feet scale, some are in meters scale, and some are in meters + feet.

There are L39 mouth and M mouth.

In the late 1950s, there were a black paint rigid version and a black paint DR version, which were good collections.

In some versions, the depth of field has a lettering at infinity. 7 or 18 represents the actual focal length of the lens is 51.6mm, 8 or 19 represents the actual 51.9mm, and A represents 52.2mm.

Kentmere 400 black and white film

Kentmere 400


The general iso400 black and white film is particularly suitable for street photography. Kodak tri-x400 has attracted many people with its powerful impulse performance, and can be forced to iso800, iso1600, or even iso3200. But today we said that this kentmere400 is the opposite of the Kodak tri-x400. Forcing it will destroy it. It is recommended that you use iso400 properly.

LEICA I model C + ELMAR 50 F/3.5 FOMAPAN100

Leica i model A B C

The Leica i was the first officially sold Leica model. The previous prototype was called the 0 series, and the original 0 series was not actually sold. Most of the cameras from 1925 are still usable, which is amazing.

There are many versions of Leica i cameras, A, B, and C models.

i model (A)
Released in 1925, the year was marked by a fixed metal bar on the front of the fuselage to lock the lens focus wrench. It is divided into anastigmat lens version, elmax lens version, hektor version, and elmar version.

i model (B)
Released in 1926, Leica’s only mirror shutter camera. The collectors like it very much, I think it’s ugly. The lens looks like a big mushroom.

 i model (C)
Released in 1930, the first Leica camera with detachable lens. In the early days, such cameras were sold with one camera and three lenses. The matching body and lens are matched and cannot be interchanged with other cameras.

The same i-model (C) and lens are engraved with the same number, or the lens can have the last three digits. Later Leica standardized the standard flange distance, making all kits and lenses universal.

Leica offers retuning of early model I (C) lenses, which are engraved with the word 0. The camera adjusted to the standard flange distance will also be engraved with 0 at 12 o’clock.

Leica i (A / B / C) cameras carry a small, long viewfinder on their shoulders. This viewfinder is only responsible for giving you an approximate range of view, not for focusing.

The black paint of the Leica i is beautiful. Leica i cameras are equipped with nickel-copper lenses, and the camera’s counter and roll button are also nickel-plated. They wear easily and leak out of brass with older Leica i cameras. These old cameras are more beautiful.
