Question about Canon EF 70-300mm f/4.5-5.6 DOIS USM Lens

1 Answer

My camera lense will not focus automatically or manually.

Lense is a Canon EF 70-300mm f/4-5.6 IS USM; Camera Canon Rebel EOS
Is there a battery or something inside the lense itself? My other lense will focus w/ no problem. I did drop my case a while back and it acted up briefly at that time, but then was doing fine. Now, nothing.

There is no battery in the lens.  The lens receives power from the camera. Whether or not the lens is getting power, though, you should be able to focus manually.
When you say you can't focus manually, do you mean that you can't turn the focusing ring on the lens, or that when you turn the ring the image does not come into focus?
If you decide the lens needs to be repaired, I recommend sending it to Canon.  You can go to their website (canonusa.com if you're in the US), click on support, and follow the links.

WILL THE ABOVE LENSE WORK WITH A CANNON DIGITAL CAMERA AND CANNON 35MIL CAMERA


Yes, it's suitable for 35mm EOS mount Canons and all digital models. If the digital SLR has an APS-C sensor then the image will be cropped and will give the same viewing angles as a 112-480mm on a 35mm camera.

My cannon rebel eos DS6041 displays error 99 when


'Error 99' indicates some problem with the AF contacts. This is a common error in Canon lenses. It could indicate a very simple problem like dirty contacts or a much serious one like the breakage of USM cable.
As a first step, you can try cleaning the lens and body contacts (the metal contacts between the lens and body) using a pencil eraser. Be careful to hold the body facing down so that no dust falls inside. After cleaning both the lens and the body contacts, re-attach the lens and try shooting. If the AF does not work still, you need to take the lens to an authorized service center.

There is a minimal focusing distance for all lenses. If you move closer to the subject than that distance then the camera won't focus on it. Check you lens manual for minimal focusing distance. It is 11 inches for Canon EF-S 18-55mm f/3.5-5.6 USM, for example.

Canon EF 75-300mm f/4-5.6 III USM Lens Auto focus motor keep working back and forth but lense is not able to stop on focus right. Had eror 01 also sometime with manual focus.


If your AF motor is hunting then the lens probably needs to be looked at. I wouldn't recommend this as something to do at home so you will need to either find a repair shop if it is out of warranty or return it to Canon if it is in warranty.

Camera won't shoot with lens on Auto Focus


Talked to canon support, they suggested to send lense in for review/repair. They said it could be the motor, I think it was a gear problem based on the noises and jerkiness of the focusing action while in manual focus (manual focus gave out as well). Cost TBD - "would definately be more than $50. I shopped around and elected to buy a new lense rather than try to hassle with the repair, shipping, insurance, and the wait, etc. Besides, I have a deadline that I need the lense for, so repair at Canon really became a non-option. I think the cost would've been pretty much the same in the end as the new lense, since this wasn't one of the costlier of lenses to begin with.

I would only suggest you might clean the metal contacts on the inside rim of the lens....just be very careful what you use....a pencil eraser is good but make sure you clean away any shavings that might get into the camera...
