Canon lens problem, what to do if Canon camera lens is wrong?

Hehe, I'm not a master, but I knew a little bit about it when I first played SLR, and I hope it can help you.

1.The difference between the lens is mainly the optical system structure, lens material, and coating technology. Both the focal length and the aperture are mainly related to the structure of the optical system.

The structure of the optical system can also affect imaging, such as correcting chromatic distortion, which of course has a lot to do with the lens material and coating technology.

2.These distinctions are certainly very useful. Shooting different subjects in different environments and pursuing different effects will not use one lens, wide-angle landscapes, medium-focus portraits, and telephoto birds; Bokeh with a large aperture, ...... with a large depth of field with a small apertureWhen you first enter the SLR, you can use a zoom first, and you can go all over the world with one shot; After a while, it's basically to buy the level of coke training.

According to the choice you provide, of course, it is better to buy 18-135, changing the lens is not only troublesome will miss the wonderful shot, but also easy to go into the dust; In fact, I recommend you to buy 18-200: compared with 18-135, although it is a little more expensive, it has a larger focal length range and is more "one shot to go all over the world"; Compared with 18-55 and 55-250, although it is a little more expensive and the focal length is 50 shorter, it avoids the trouble of changing lenses for 18-55 and 55-250. FYI

18-135 will do. Don't buy too many APS-C lenses. Later, I have spare money to buy the full frame.

Double-headed good. Full focal length and good usability.

Look at my space, there are some information on the lens, I hope it will be helpful to you.

If you are new to SLR, it is recommended to choose an 18-200mm lens, and one lens will solve all the problems.

All three heads belong to amateur dog heads, except for the difference in focal length, there is not much difference. The imaging quality is average, and it is enough for amateur play.

All three heads are dog heads, so choose the focal length according to your own shooting needs.

Hello, one, battery problems.

1) If you use a Canon camera outdoors, if the temperature is too low due to cold weather, the battery will be insufficient, and the lens will not retract.

2) The battery is dead or encounters a fake battery, which does not have enough power**, which will cause the lens to make an error;

3) The battery is not installed in place.

Solution: Turn off the camera, remove the battery and put it back on. If that doesn't work, try replacing it with a new battery or charging it.

Second, the lens is malfunctioning.

Generally, the camera lens cannot be retracted, because the lens is artificially collided and distorted, and the result is often that the lens cannot be retracted. Impacts by external forces, or when foreign objects (sand, etc.) enter the lens can also cause Canon camera lens errors.

Solution: Shake the camera lens downwards or gently tap the lens to see if you can eliminate the slight stuck foreign body in the lens. Recall whether you have collided with the camera, and if the lens is slightly tilted and cannot automatically retract back, do not force it to press back.

3. Mechanical failure.

Mechanical failure generally refers to the quality problems of the motor, gear, rack and other quality problems in the camera. The retraction and extension of the Canon camera lens is operated by the gear system, and the failure of the gear or the power supply of the system can cause the lens to fail.

Solution: This kind of fault is a fault, you can not complete the repair work, it is recommended to send to the maintenance point, so that professionals can investigate a series of problems of motors, gears, racks, etc., investigate the root cause, and then repair or replace the relevant internal parts in a targeted manner.

If your Canon camera has been used for a long time, if there is a problem with the lens, it may be that it is about to run out of life, and you can consider replacing it with a new one. If you haven't used it for a long time and you can't solve the problem of the Canon camera lens error, the way is to find after-sales maintenance, and there is no charge for after-sales service within the warranty period; But if you don't understand the cause of the failure, you will make a fool of yourself, which may cause a bigger failure, and then send it to the repair point too late, and you will have to pay double or even higher maintenance costs.

1. Reason: The failure of most of the camera department is the lens failure, because this is a mechanical part, which is easy to be hit by external forces, and when foreign objects (sand, etc.) enter the lens, it will also cause lens failure. There was a problem with the transmission gear that drove the lens.

2. Processing: 1. Unplug and reinsert the SD card. Reinstall the battery.

2. Replace the battery with a new one or charge it.

3. Gently pat the lens or give force, don't use too much force, and the slight jamming foreign body in the lens can be eliminated.

4. If the above cannot be solved, it is a permanent fault, such as transmission gears, tracks, etc., which have to be sent for repair.

Hello, there are several possibilities for the camera lens not to retract:

1.The battery is drained.

2.Lens zoom motor malfunction.

3.The lens focus unit is jammed.

4.Deformation or malfunction due to external forces.

If there is a problem with the lens, it may be that the motor gear in the lens is broken, and when it is not zoomed, it does not turn to the broken tooth position, and as soon as the zoom turns to the bad gear position, it will naturally shut down.

I tried to knock ten times in each of the six directions in the palm of my hand, and I succeeded when I tried to get to the fifth position.

Wiping the lens clean should do the trick.

I'm having the same issue with my camera and have fixed it myself.

I'm experiencing this situation too! I filmed, and it wasn't good. What to do with manna! I didn't touch it at all, that's all! Canon, what's wrong with you, wow! It can't be like this, can it?!

Canon cameras can use not only Canon's own lenses, but also lenses made by other companies, in three ways:

1. Auxiliary lens.

Such as: Sigma, Tuli, Tamron, Sanyo, Volenda, Carl Zeiss, etc., these manufacturers produce their own brands of lenses for Canon mount, which we commonly call analogues.

2. Through the adapter ring.

Such as: Leica R mount to Canon EF mount Contaise Y C mount to Canon EF mount, these adapter rings act as a medium between the body and some lenses, so that they can be combined and used normally, this kind of lens is generally a manual old lens, with an adapter ring with electronic contacts, which can make the camera focus prompt.

3. Change your words. Such as: Leica R mount to Canon EF mount, Contaishi Y C mount to Canon EF mount, this kind of modified lens is similar to the use of adapter rings, except that one is through additional media, the other is through the production process to transform, the change is irreversible, so you should be cautious.

Above, the first type is suitable for everyone as long as you have money, and the second and third are suitable for people who have a certain understanding of photography and equipment, and most of them are people of a certain age, and many of them are the pursuit of equipment, not the pursuit of photography.

No, there are original or sub-factory lenses, as long as they are Canon port, pay attention to EF and EF-S, if you have other lenses in your hand and don't want to change them, you can consider the adapter ring.

I'm in photography, and I know better, I'm using Canon 5D now.

The lens can also be used by the analogue, such as: Sigma, Tamron, can be. But there is a small problem, shooting makeup, portraits, after magnifying it will be a bit empty. This is a common problem for the head of the deputy factory.
