Siheyuan: After being robbed of marriage, the traveling frog returns

Chen Fen nodded, walked over and shook hands with him, "Hi, I'm Chen Fen."

"My name is Liu Weiguo, you can call me Old Liu."

"Not too good, leader!" Chen Fen knew that these leaders like to make a gesture of being close to the people.

If I really called him Lao Liu, maybe he would start scolding his mother in his heart.

Unexpectedly, Liu Weiguo laughed loudly, "It's okay, everyone calls me Lao Liu."

"Then I'll call you Uncle Liu."

"Alright." Liu Weiguo patted Chen Fen on the shoulder, "Sit down for a while, and I'll get you a cup of tea."

"I just drink plain water."

"Don't be restrained." Liu Weiguo looked cheerful and asked someone to serve Chen Fen a cup of tea.

Then he sat down at the table and started talking to another middle-aged man.

"Wang Gong, can you fix it?"

The man named Wang Gong had a complicated look on his face, "Old leader, this camera of yours is a new Leica model. I already know what's wrong with it, but I don't dare to dismantle it casually. This camera can't be restored by ordinary people."

"So troublesome?"

"Yeah, people have used the most cutting-edge technology, so there will naturally be anti-dismantlement to prevent reverse engineering counterfeiting."

"So besides the people from the original Leica factory, other people really can't repair it?"

"Probably so."

Liu Weiguo looked sad, "This is a gift from my wife. You know that my wife just left last month, and this is the only camera left for me to see things and think about others."

"Hey, condolences to the old leader."

Listening to the conversation between the two, Chen Fen probably understood what was going on.

This Liu Weiguo is quite pitiful. His wife passed away, so he cherishes this camera very much.

But this Wang Gong seems to be knowledgeable.

Just as he was thinking, Liu Weiguo cast his eyes on him, "Xiao Chen, I heard from your factory manager that you know a lot about cameras, why don't you take a look?"

Chen Fen stood up when he heard this, "I'm here today for this purpose."

"Old leader, you asked this little comrade to repair the camera?" Wang Gong looked in disbelief.

"This little comrade is not simple, he is an engineer in the factory."

"I didn't mean to look down on this little comrade. It's just that there are many precision parts and optical components in the camera. It's really not something an ordinary engineer can repair."

"Hahaha, it doesn't matter if you take a look." Liu Weiguo could see it, "By the way, I forgot to introduce you. This is Mr. Wang, an engineer from Haishi Feiyan Camera Factory."

Wang Weiguo introduced them for the sake of the two, but Wang Gong stood up and shook hands with Chen Fen.

Chen Fen didn't care about what Wang Gong said just now, shook hands with him and walked to the camera.

At this time, Wang Gong said again, "Comrade Xiao Chen, I advise you to take a look. Don't have any ideas to repair it. Let the old leader send it to the original German factory for repair."

"It's so troublesome." Chen Fen picked up the camera, "Uncle Liu, what's wrong with your camera?"

"The photos taken are very dark. If the sensitivity is adjusted relatively low, or the shutter speed is too fast, the photos taken will be completely black." Liu Weiguo talked about the problems with the camera.

"I see." Chen Fen turned the camera over.

Seeing him being so careless, Wang Gong was startled.

Just as I was about to remind him to be careful, I heard Chen Fen introduce this camera.

"Leica MD, produced in 1965, detachable lens, this is a 17 fixed focus, which is the standard lens..."

Chen Fen reported various parameters of this camera, such as the maximum exposure value, the slowest shutter speed and so on.

Hearing this, Wang Gong and Liu Weiguo were taken aback for a while.

It took Liu Weiguo a long time to come back to his senses, "Your director is really right, you are really good at cameras."

"I'm not an expert, I've studied many cameras."

Wang Gong on the side also grew his mouth, even though he was engaged in the camera business.

Nor can he open his mouth like Chen Fen so much data.

It's as if the camera was designed by him.

Moreover, this camera was launched by Leica last year, and there are very few people who know such accurate data.

Their factory also spent a lot of effort to get the data of this camera, which is exactly what Chen Fen said.

He became a little puzzled, how could an engineer from a small factory know so much?
Although Chen Fen is now a second-level mechanical engineer, he is not so perverted that he is familiar with the parameters of various machines.

The reason why he knows so much is because he studied this kind of film camera in later generations.

There are not many people who use film cameras in later generations, and they belong to a relatively small group.

It just so happens that Chen Fen has such a niche hobby of retro, and has also collected several film cameras.

Among them is a Leica MD1965.

Seeing that Chen Fen could tell so much data, Liu Weiguo trusted him a little more, "Since you understand so well, quickly help me to see what's wrong and whether it can be fixed!"

Chen Fen nodded and opened the back of the camera.

There is a roll of pre-loaded film inside, which can be used directly by pressing the shutter.

He adjusted the shutter and sensitivity of the camera, and took a photo with each parameter.

The most prone to problems with the camera is the photosensitive element. If there is a problem with the photosensitive element, it can be seen from the photos taken.

Sure enough, he turned the sensitivity to the maximum and the shutter to the slowest.

As a result, the film was not completely black.

It stands to reason that for photos taken under such parameters, the film will become black due to overexposure.

This proves that something is wrong with the components of the camera that receive the light.

Either the camera itself, or the lens is faulty.

He skillfully removed the lens and checked the mirror of the camera.

Then he discovered an interesting thing, as if there was nothing wrong with the camera itself.

Seeing this, he laughed, "Uncle Liu, have you checked the camera?"

"Camera?" Liu Weiguo was taken aback, "What's wrong?"

"Look here!"

Chen Fen put the lens in front of Liu Weiguo and asked him to observe the inside of the lens from the aperture.

But Liu Weiguo, a layman, didn't see anything.

Wang Gong was a little curious, "Can I see it?"

Liu Weiguo handed the lens to Wang Gong, and after he took it, he pointed the lens at his own glasses as if looking through a telescope.

After watching for a long time, he exclaimed, "It turns out that something went wrong here, and I ignored the camera. Comrade Xiao Chen is really careful."

Seeing Wang Gong's appearance, Chen Fen knew that he had also discovered the reason.

But Liu Weiguo was at a loss, "Where is the problem, why didn't I see it?"

"Of course." Wang Gong said with a smile: "Old leader, you just like cameras. This problem is not obvious to professionals. It proves that Comrade Xiao Chen is very skilled!"
