Can the Canon 17 85 lens ER99 be repaired

Can be repaired, just change the cable, the cable ** buy 10 yuan, but it still requires a certain amount of technology, it is recommended to find a professional, otherwise it is easy to hurt the inside, affect the imaging quality or unable to focus. In addition, since this problem is a lens design issue, it will still recur after the fix as the number of times the lens zoom is used.

I don't have this lens, but I've always wanted to buy it, so I'm very concerned about the situation with this lens. What I learned is that the ER99 error you mentioned has a high proportion of occurrences, because when the lens is zooming, the lens expands and expands back and forth, driving the aperture data cable to continue to stretch and flex, and after a long time, one end of the aperture is in poor contact or even broken, accompanied by abnormal aperture contraction.

This problem is a design problem, and the lens needs to be removed for repair, but because it is a common problem, it is not difficult to repair. The charging standard should be consulted at the maintenance point.

There is something about the camera itself settings.,Clear all self-settings.。 The biggest possibility is the lens, after turning off the lens, take off the lens, and then use the lens cloth to wipe the metal contact points on the camera and the lens clean and then put it back on, after turning on the camera should be normal.

If there is a professional to solve the problem of cleaning up the lens or some problems on the lens, it is recommended that if the appeal method is not easy to use, find a professional to check, and the major digital ** inspection is generally free of charge.

I consulted this question on Canon's official website, and the landlord can also try it.

What does the Canon 17-85 lens repair? General maintenance for half a year.

Canon's authorized repair stations have a long service life after replacing genuine parts. If it is repaired elsewhere, it is not guaranteed.

It is highly recommended to buy this lens.

Our company has been open for 20 years, and we used this lens a few years ago, and all the cables were rotten again and again, and the lines of this lens were very problematic.

The picture quality is meaty. The aperture is too small.

It is recommended to buy the new 15-85, 17-85 upgrade. Bigger aperture, bigger aperture, wider angle, better workmanship.

Truth be told, there are 99 regrets about buying 17-85-100.

Rather 18-135 is counted.

Either red circles or no focus.

Congratulations.

Canon SLR err99 seems to be a common problem, you search for Canon err99 error on the Internet, you will find a lot of netizens complaining, this is an unknown cause error, perhaps because of the electronic contact reason is also unknown. Rebooting or reinstalling the lens can be eliminated, there is no other way, and there is no after-sales help.

Presumably it's a circuit problem, because the aperture of Canon's lenses is electronically controlled, and you can see that the aperture is narrowed. By default, the aperture is kept wide open.

Personality vouch: I had this problem with the machines I used in the company. And it has already been sent for repair.

Mine is the lens sent to the canon designated repair center for inspection after the lens inside the focus module problem.

It took 300 yuan to replace this module.

PS: The focus sensor is inside the body, and if that thing is broken, it's not normal to change the lens

Now your situation can be determined to be just a lens issue.

Did you turn your head or? It is recommended not to go to the official maintenance department, and the maintenance fee is mainly based on the actual local area.

Hehe, there's something wrong with your lens. The same was true for the D300's lens last year. It took more than 200 repairs.

350-400 I'm from the image repairer, and I'm in Chengdu.

In general repair shops this problem does not exceed 200

When you turn the lens to the MF gear, look at the small screen on the lens, it will change with the rotation of the zoom ring, the nearest is the leftmost number with the smallest number, and the farthest is the + symbol, at these two times, even if you turn the zoom ring, it is useless, because the focus limit has been reached. If it's not this kind of problem, there should be something wrong with the zoom ring, mind going to a professional repair shop to fix it.
