My OM-D is noisy!
Mar 31, 2012

As I posted before, I picked up my OM-D this morning.

The batteries are charged and am now trying it out.

Here is what I notice right off the bat. My OM-D has a constant electrical hum. Kind of like a hard drive, fan, or O.I.S. stabilization system.

It's not the new lens since I've switched it to another and the hum continues. Switched off the I.S. and still noise.

Any ideas?

In another thread someone was told at the store they bought it from that the sound was coming from some sort of stabilization in the EVF.

I have it too, but I didn't even notice it at first, or even consider it worth commenting on if it hadn't been brought up here first. I don't consider it an issue at all, do you?

it isn't an issue IMO... just something unexpected and I wanted to confirm it wasn't a malfunctioning unit or lemon.

charging up the batteries and looking forward to possibly some tests in the rain.

I'm sitting in a quiet room and am finding it to be quite noticeable. It never goes away, even if I'm changing settings in the menu, the sound is there. It's constant.

If it's a lemon, then we've all got lemons!

To me it sounds like the kind of Gyro sound I get from my Canon 70-200mm f4L lens with I.S. on, which bites when doing video with only the camera's mic.

I hope there is a way to shut it off. If not... Oly firmware developers take note .

I would ask one (or several) of the early reviewers about the noise - whether they have noticed it.

EVF stabilization fiasco!
In reply to Chris_in_Osaka, Mar 31, 2012

Is there an option to switch off EVF stabilisation?

Why would there be an "EVF" stabilization?

I used to shoot Pentax for a couple of years. Their IBIS is also based on magnetic control of the sensor stabilization. That's different from a motorized system (as Minolta/Sony and earlier Olympus models) as it has to work also when the stabilization is turned off; the magnets has to keep the sensor assembly in its right position. A motorized system just need to have the motors turned off.

The Pentax K10D made a clonky sound when turned off - that was the magnets dropping the sensor.

I wonder if the Olympus new IBIS system make this noise all the time as the magnet controls has to be turned on regardless of the IBIS setting.

If the camera is supposed to work this way I wonder why it hasn't been noticed by reviewers this far? Does it has any practical bearing on anything?

regards,

Jonas

If noise gets recorded, that will be a problem for the video depending on the situation.

I don't know... Maybe a focus group request? It helps composing with long and macro lenses apparently.

Maybe the reviewers were focused on more obvious aspects.

(assuming it is IBIS .. and leaving video out of the equation):

  • it causes an unnecessary drain on the battery

  • it causes the camera to overheat under hot temperatures (and hence, having negative impacts on the SNR of the sensor.. or worse, forcing the camera to shutdown)

Both are likely .. since it was one one of the main reasons (particularly my 2nd point) why IBIS was only switched on during the shot itself .. and not clear (yet) how Olympus worked around that issue.

Please keep reporting on this..

Thanks !

For me it is a non-issue at this point, but I will keep an eye on the issues you point out and see how it goes. I'll report back in a couple of days.

As far as I can see the IS will always have to be on, even if it isn't moving the sensor, to hold it steady. I'm not certain that's the case, I did try to ask about it, but I just got the usual bunch of ignoramii telling me that nothing Oly makes could ever go wrong and how wonderful IBIS is.

MEMS gyros
In reply to Chris_in_Osaka, Mar 31, 2012

I'll bet that part of the IS system is MEMS gyroscopes ( http://en.wikipedia.org/wiki/Vibrating_structure_gyroscope ) and that's where the sound is coming from.

I find it strange that none of the early preview bodies that that were in circulation seemed to have that issue. For example here at least two Finnish photographers (whose opinion I trust a lot) had a chance to test and review OM-D for several days in various situations and also at home (not only at some noisy exhibition stand) and neither mentions that noise. It was the same body that they had so apparently that one did not make any irritating additional noise. I did not pay attention if Mr Wong mentioned it in his lenghty previews? But he was mostly shooting outdoors so one probably pays attention to it only in otherwise completely silent surroundings... or in the worst case something strange has happened in between.

Vlad, I wonder how many of the reviews/first looks from the past were production models or if all were pre-production?

Louis, this is the first time any Olympus camera has made a noise when the stabilisation system is inactive. When you asked about it, you were given the best guess based on previous experience and available information at that time - how does your interpretation read?

My guess at this time is, that stabilisation is continuing to run to stabilise the EVF - it may be possible to switch that off.

Cheers
