How is the lens aligned?

Adjustment of the lens may be violated for various reasons. What to do in this case? How to restore images to their former sharpness and clarity?

Types of problems

One of the most common causes is the violation of autofocus. It can be the result of active or prolonged use of technology, but it also occurs on new devices.

Another possible cause is a violation in the autofocus of the lens itself. This is found on many models, especially for cameras with zoom function. And violations can be different at large and small focal lengths.

The reasons for which lens alignment is required:

• Incorrect adjustment at the factory.
• "Shaking" the lens, increasing the gaps and backlashes during long-term operation.
• Falls and blows.

It is worth noting that the alignment of the Canon lens is not always required. Sometimes there is a "glitch" because of the specific type of artificial lighting. That is, autofocus goes into flight or undershoot. More often such features are noticeable with the included energy - saving lamps.

To check this, place the camera on a tripod, then at a 45-degree angle, point to the ruler. Pictures should be taken with autofocus. Only energy-saving lamps should be switched on. Then let the lighting give only incandescent lamps. With a high probability you will see a flight on the pictures with energy-saving devices.

The service centers say that modern models are less prone to such a phenomenon. Fighting this defect is useless and pointless. In addition, he usually does not create tangible difficulties when shooting.

How can lens alignment be restored?

The most reliable and correct way is to contact a specialized service center. And they will outline both the "carcass" and the lens. If your camera is still on warranty service, this procedure will not cost you anything. If not, you will pay a relatively small amount.

Usually such manipulation takes a week. But the financial stimulation of service men can bear fruit. It is quite real that they will cope for the day.

The second variant of how the lens can be adjusted is the tuning in the tuning of the carcass. But in some new cameras this option is no longer there. The probability that you will manage to change something is. But it is very difficult to do this in practice. Not to mention the cases when you need to adjust the zoom lens, which has various violations of focus at different distances. In such cases, this method does not help accurately.

But if you need to adjust the lens of Sigma, Tamron or Tokina, this is an acceptable method. After all, there are no intelligent specialists working with such devices in Russia. Or they are extremely difficult to find.

But remember that this process is labor-intensive. In addition, the temperature and type of target are significantly influenced by autofocus. It is unlikely that you will be able to recreate the laboratory conditions that are in the service center.

Of course, you can customize it yourself. But this is not recommended. You are more likely to damage the technique than to set something up.
