What do you fear most? Waterproofness, tideproofness, shockproofness have always been the three top stars in the lens. Waterproofness is now much better than before. A sudden vibration or bump could cause total damage to the camera, and the following case is a reminder。
Why is the camera in the bag broken
Last week, a user sent a sony 24-70 gm camera, saying that it was always in a bag, well, it was a problem when it was recently used, it was not possible to identify the radial, and the camera opened the cylindrical number without showing it, showing only “f-”。
I took a look through the camera. There were no signs of damage, but it looked good. I asked him if he'd ever fallen? The user then recalled that he fell in a bag the previous day and fell on the ground. As the camera was in the bag, it was not so bad that it was checked, without any damage or care. It's not like it's broken because of this wrestling
In my experience, it's the camera that's been shaken and the internal parts are in trouble. What's the problem。
Maintenance process
As sony's master g shot, the work is solid, the hands are heavy, full of quality。
24-70 mm is one of the most common focus sections that can satisfy most of the shots and is the preferred shot for photographers。
Start dismantling the machine, starting with the screw at the bottom of the lens。
Every step of disassembly requires a check to see if there is any broken ground, where everything is well and continues to go down。
Several large pieces have been dismantled and no problems have been identified. In terms of internal construction, the lens is designed very closely。
It's almost eight pieces of the camera, and it's still not a problem, and it can't be shown from the light of the camera, if it's the ultrasound-to-jomada problem, which is the easiest place to get into trouble。
It's an optical assembly. Look at the look. Keep going。
It's a direct ultrasound-to-fossor group. It looks normal here。
This is the part that directly drives the ultrasound to jomada, which can be seen to have broken, as follows, as if a small part. This is not a small spare part, and general maintenance will not be removed to this point, and the entire giomada group will be replaced with a high maintenance cost。
In the early stages of the fec, most of the sony lenses used linear-to-jomada, followed by high-end products such as fe 35mm f1. 4 za, fe 24-70mm f2. 8 gm using ddssm to drive ultrasound pomada. While the conventional linear motor mix with the phase-focused system has already performed well, the straight-through ultrasound pomada is more accurate while the mirror is smaller. One problem, however, is that this place is a weak link in the lens, and there is a risk of a break in a vibration, such as this case. I wonder if anyone else has ever met this problem
Put on a new jomada and get it ready for testing。
Let's get back to the last two steps。
Final installation completed and a full cleaning of the camera。
Put the camera on the fuselage, test. The aperture is normal and it's ready to be shot again. The general maintenance was replaced by the entire ultrasound-to-focal team at a cost of around $1,500. From the point of view of economy, only ultrasound pomadas were replaced, resulting in half of the cost savings. So when using the lens, it is important to prevent vibrations and bumps, and to buy a good bag for the camera, with a lot of guts。

About the internal injury
The lens is a sophisticated instrument with a large number of internal parts, and the more advanced the lens, the more complex the internal structure. It's usually hard for us to use it normally, and most people use it for more than a decade. But if external causes, such as vibration, can easily cause internal damage to the lens, this is a more depressing problem。
How to avoid camera vibrations? It is wrong to have the right usage habits, for example, when a camera is used, many people are used to putting the body around and the camera is going out. The right thing is that the camera closes, the fuselage goes out, a little bit of the body falls off the paint, and that's probably a big problem。
This allows a large number of countervailing users to do so during their work and is easy to film at any time。
In the absence of work, the camera should turn back and avoid a bump in the camera。
There are also a number of people who leave their cameras in the car at random, and who are vulnerable to camera damage by bumping in the drive. Finally, it's a photo bag, which usually doesn't work if you buy a cheap photo bag from a camera. Once a good habit is developed, the chances are small. With regard to the lessons of the camera accident, one can read the earlier article: "ten ways of death for the camera and the camera, the lessons of blood must be seen"。
