Groaning gyros

Scott, I have had to send two lenses to Canon, both were back within two weeks---if thats any consolation.





Good Luck

[Scott]

Yeah I think I'm getting screwed over with the time it is going to take. I did forget to mention I'm in Queensland, Australia and it has to go to Melbourne. The joy of living in the lucky country I guess. It just annoys me as it is costing me money and they said the only loan lens they can give me is a nifty fifty, groan, whinge, bugger.

Come on Canon is that all the better you can do? The lens is defective why are you chargingthe customerfor the shipping, it's your fault.[:@]


This just makes no sense.

I've never had that problem but anytime I've sent something to Canon for repair it has never taken more than a week and a half from the time I shipped it.

<span>I have a 24 &ndash; 105 f/4 L which has been diagnosed with the gyros not stoping and noisy, very noisy

Hi Scott! Who diagnosed this behavior? Gyros do not make noise, actuators (the motors moving the stabilizer lens or lens group) do. Unfortunately, this does not solve your problem.


The fact that the lens is very noisy comes down in favor of a mechanical problem; on the other hand, the noise stopping only when the lens is off the body would suggest a different cause. Electronics may sometimes "go insane" when exposed to strong electromagnetic fields, excessive heat or other kind of physical stress...


Apart from the abnormal noise, is your 24-105 functioning (AF and IS)? Can you tell if IS is working properly by looking through the viewfinder at 105mm, even if now you can't compare IS off/on?


That's quite an intriguing problem... I couldn't find anything similar googleing the web... Please, let us know how all this will end up. Good luck!

I'm no direct expert, but gyros are a moving part, so they can make noise.

I'm not an expert either, but a properly balanced and functioning gyro wouldn't make a noise that we could hear, but I could see a faulty gyro making noise. The actuators do make a noise that is normal and some (all?) lenses they even make a little clunk.

I'm not a Daniel Browning clone, either[]... Nonetheless, to the best of my knowledge, gyros used in Canon image stabilizers are not much different from those present in several other devices including iPhones, Wii controllers and some laptops, just to mention a few of them. Basically, they are microaccelerometers. Canon defines them vibration gyro (angular velocity sensor) and acceleration sensor to indicate, respectively, the gyro implemented in the conventional image stabilizer to compensate for angle camera shake and the one added to the new hybrid IS which compensates for shift camera shake. There are no spinning parts in such gyros, the Canon technology is based on murata-type prismatic beam gyro (have a look here) and therefore, faulty or not, they can never produce even the faintest noise.


@Scott: hope you managed to have your 24-105 fixed the soonest... btw, apart from the impossible-to-switch-off groaning, whatever the cause, does it work despite the noise?

Here is the only gyros that I've had, and eventually, they will make you groan! []
