Keep the film away from moisture

The film has risen a lot recently, and it has become very important to preserve the film. Use a thick airtight bag to seal it, then put it in the refrigerator, let alone i50mm not remind you when it gets damp, and put some paper in it to prevent moisture. Get it from the freezing to the refrigeration, and then take it outdoors overnight. Even if you don’t put the refrigerator, put some paper in it. After all, summer is here and it is raining or humid.

Choose a school or a major for the college entrance examination? Choose Leica or other cameras?

Zheng Qiang is particularly good about choosing a major or choosing a school: “Anyone who wants to be a craftsman or who wants to find a job should choose a major for a job. Those who want to do more high-end management, etc., choose a school with a more confident life. , Because the school culture supports a person.”

This sentence is particularly good, and it does have some truth. Many people know that even if their majors are tested, they don’t make much sense, but they still have to test them. The purpose is to increase their confidence in a prestigious school. Wah.

Root Leica is very similar. i50mm: “Anyone who wants to be a craftsman or looking for a job chooses another camera for a job. For those who want to do more high-end humanities and more literary life, choose Leica, because Leica culture supports the history of photography. “.

So i50mm tells everyone that you must use a leica camera, because what you see is comprehensive and the confidence you get is full. Wow haha.

Statistics show that 99% of those who visit the i50mm website have a bachelor degree or above, while 99% of the content on the i50mm website is Leica-related. Of course, if you are the 1%, it is even better, you are the one in the hundred. In short, looking at i50mm wow haha, they are not ordinary people.

What happened to the Leica m6 bubbling?

The Leica m6 coating leaves the base low and swells due to partial loss of adhesion, causing the surface to appear as a round convex deformation. The bubble may contain steam, other gases or crystals. In general, this phenomenon is due to the bubbles generated by the surface coating, and the gas may contain organic substances, microorganisms, and even corrosive chemical components. In the process of coating and film formation, the bubbles are flattened, and with the increasing pressure, the bubbles of the cousin’s coating are finally squeezed out.

In fact, the cause of this phenomenon in Leica M6 is likely to be that Leica m6 period reduced some processes, because m6 sales exceeded expectations. In order to increase production, the factory reduced some process processes that had no obvious effect. Of course, this is only a guess for i50mm.

kodak tri-x 400TX + leica 21 f3.4 super angulon

Films for Leica Centennial

The Leica 100th Anniversary Limited Edition M100 set contains the Leica M-A + Leica M Monochrom combination. Also included is a film, which is Kodak tri-x 400TX, Kodak’s legendary black and white film.

This is also Kodak’s most popular black and white film, with a high dynamic range, a variety of processing solutions and forced flush solutions. It is called “film that can be developed with water.” It is a favorite of news reporters and photographers from Magnum. Leica’s 100th anniversary model chose this film, showing how high 400tx is in the photography world.

Very high dynamic range

The kodak tri-x 400TX has a very high dynamic range, which is very useful for human photography and street photography that need to be quickly captured. Many times you have no time to adjust the aperture and shutter speed. In these areas this requires negative film to have a higher dynamic range. Many people will use Kodak 400tx as iso800, iso1600 film, and double or double the development time when developing. Some people use it as iso100, iso200 film, and then shorten the development time appropriately. The kodak tri-x 400TX gives people more freedom to play, which is one of the main reasons people love it.

In the 21mm lens, LEICA 21mm f/3.4 LEITZ SUPER-ANGULON is the most special. A total of about 6,000 diameter lenses are produced. It’s a pity not to experience Leica’s super wide-angle lens. LEICA 21mm f/3.4 LEITZ SUPER-ANGULON, the color is thick, just like the thick sense of history.

LEICA 21mm f/3.4 LEITZ SUPER-ANGULON is designed and produced by Schneider, Germany. This is the second marriage between Leica and Schneider, the first time is the lens of leica 5cm summarit f/1.5.

LEICA 21mm f/3.4 LEITZ SUPER-ANGULON has not been updated from 1963 to 1980. Until the Leica m5 was compatible with this lens, the m5 could not be metered. Leica was redesigned.


It started in 1958 and ended in 1980.

The first version of Super-Angulon 21mm f/4 is designed and produced by Schneider and sold by Leica. They are all silver and have L39 screw and M ports. 0 distortion.
The second edition of Super-Angulon 21mm f/3.4, silver is rare, and the black version was produced in the late 1960s. Available on leica M9, ​​M8, M6, M7, MP, Minolta CLE, but cannot meter. The lens number is 2,473,252. After the transformation, it will no longer affect the metering of the fuselage, and it can be used on M5 and CL


Filter: 48mm UV, VII.
Hood: 12501
Front cover: 14102
Rear cover: 14042
Stock: less than 6000.
Focus lever: metal crescent focus lever.
Minimum focusing distance: 0.4m

Although it is available on the leica M9 digital camera, the screen will appear red-shifted and cannot be metered.



Although there are only four aperture blades, the bokeh is still very smooth. The closest focusing distance of 0.4m is equivalent to f/2 bokeh at a distance of 0.7m for a 35mm lens.


This color is very outstanding.

Black and white film

Like ink painting, the layers are very beautiful, and the picture is thick and heavy. Quickly look at the old black and white movie of Hitchcock, it really looks like.


Sharp enough.

Eating light lens —— Leica eica super angulon 21mm f/3.4

Leica leica super angulon 21mm f/3.4 + kodak tri-x 400

Leica’s first 21mm ultra-wide-angle lens was manufactured by Schneider of Germany. This 21mm is the famous leica super angulon 21mm f/3.4.

Eating lens

It is generally believed that the Schneider lens eats light, which means that it will not be overexposed. At the same time, Schneider’s design is often accompanied by dark corners and dark parts.

Schneider Tradition

The 21mm f4 and 21mm f3.4 Super Angron designed by Schneider for Leica are such “eating light” philosophy. Including large-format lenses is also this tradition, and is loved by experienced users.

Leica leica super angulon 21mm f/3.4 + kodak tri-x 400

A philosophy different from Leica

Leica lenses are good at showing details in low light and natural grayscale. Leica is not as good as Schneider in controlling the highlight overflow.

High contrast unlike any other

Generally speaking, a high-contrast lens takes two extremes, the highlight is very bright, and the dark light is very dark. However, leica super angulon 21mm f/3.4 is that the highlights are not very bright, and the dark areas are dark enough.

Leica 50mm f/1.4 summilux pre-asph e46 Titanium reviews

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.

Black, silver, titanium, L39 mouth.
The e46 black paint limited edition is sold with a black paint camera.
The titanium version is not titanium alloy, but brass-coated titanium.

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.

Leica 50mm f/2 Summicron Rigid

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.

leica elmarit-m 28mm f2.8 asph

leica m3 + summicron-m 90mm f2

leica elmarit-m 28mm f2.8 asph
This is a Leica compact 28mm lens. The f/2.8 aperture is good for a wide-angle head. It was not my original intention to buy this elmarit 28mm, it was bought with the camera kit.

This is an asph lens. Compared with pre-asph lens, its advantage is small, but its disadvantage is lack of personality. Compared with summicron 28 f2 asph, elmarit-m 28mm f2.8 asph has only price advantage.

My favorite Leica 28mm lens is elmarit 28mm f/2.8 v1. It is the only 0 distortion lens in the Leica 28mm lens.

Although the later ASPH version has improved corner sharpness, the old version of the lens is still irreplaceable.

leica m3 + summicron-m 90mm f2

Leica elmarit-m 28mm f2.8 asph is sharp when focusing accurately, and elmarit 28mm f/2.8 v1 is more three-dimensional when focusing is not accurate. In fact, street photography is often too late to focus.

leica elmarit m28 2.8 asph is digital friendly, there is no doubt about it. It came along with the Leica m8.

leica 35mm f/1.4 summilux pre-asph leica glow review

leica summilux 35 1.4 pre-asph

Leica fans have at least two 35mm lenses:

There is a sharp lens, as fine as a needle, capable of stitching time with water.
There is a soft lens, it is as sweet as cherry, and it can feel sour with eyes.
leica summilux 35 1.4 pre-asph, with both personalities. It has the characteristic “leica glow” that many people like.

In 1960 Leica released the world’s largest 35mm lens. The world’s smallest 35mm lens with 1.4 aperture. It is the longest lens produced by Leica.

Many people used leica summilux 35 1.4 pre-asph, but could not find leica glow. Leica glow does not appear just by taking a photo. When? When the aperture is f1.4, photograph the object in the noon sunlight.

where is leica glow

I’m talking about being in the sun, not talking about shooting at the sun! If you are stupid enough to shoot at the sun, then you will not find leica glow, you will find light leakage, the shutter curtain is burnt! If you don’t use f/1.4 aperture, sorry, you can’t see leica glow. If you are in the shade, sorry, you will not see leica glow. If you are indoors, sorry, you will not see the Holy Light.

leica summilux 35 1.4 pre-asph

You will only see leica glow under strong light and high contrast. It’s a cloudy day, under the shadow, and indoors, it turns into a great lens, and the aperture of f/1.4 can also be trusted.


Leica summilux 35 1.4 pre-asph is 80% similar to summicron 35mm v4 at aperture F1.4.
Leica summilux 35 1.4 pre-asph is 90% similar to summicron 35mm v4 at aperture F/2.
Leica summilux 35 1.4 pre-asph is 99% similar to summicron 35mm v4 at aperture F/4.

leica summilux 35 1.4 pre-asph VS summilux m35 1.4 ASPH

The asph version is the winner at any aperture. But in size, pre-asph is the winner. Many people like leica summilux 35 1.4 pre-asph mainly because of its small size.
