Re: E-M1 mystery noise (and battery life) issue

I have no experience of the 12-40 specifically, but sometimes some of my lenses "chatter" the diaphragm when the camera is switched on, as if they are reacting to light level changes even without being activated.

PS Panasonic lenses are notorious for doing this.

Re: E-M1 mystery noise (and battery life) issue

Just an update on one of my comments - what I thought was a change in the Live View to noisy screen is actually due to the screen being set to magnify to allow more precise focusing when using MF - in low light conditions that I have here it looks like a mess of noise initially but it is actually due to the Magnify setting - this is accessed via the Menu, Cog A, MF Assist, On

Regards
Chris

OK that should rule out the aperture blades ... although Stephen's commented more specifically above.

Re: E-M1 mystery noise (and battery life) issue

Do you have the rear touch screen activated. If so the lens might be focusing when you touch that. Just a thought.

Re: E-M1 mystery noise (and battery life) issue

If you are fortunate to have access to a legacy lens, try fitting that and then dialling in an inappropriate focal length (on a 50mm lens set the FL at 500mm). When this is done the IBIS goes berserk trying to stabilise the image. If the noise that can be heard during this is the same as you hear at present then you can be sure it is due to the IBIS and may be normal.

My chosen mode also, but the 12-35 does it in that mode - sometimes!

Re: E-M1 mystery noise (and battery life) issue

I have recorded the sounds using my (Olympus :-) voice recorder held against the underside. IT clearly demonstrates what I am describing but unfortunately I can't upload an MP3 file here. Happy to e-mail it though if anyone interested in giving me their thoughts.

Is it the same as this one that's been recorded by someone else (whose trying to understand what it is)?

Re: E-M1 mystery noise (and battery life) issue

That sound is the same as mine. I'm pretty sure it's the IS working. If you deliberately shake the camera slightly when it's happening in live view you will see it working.

his accompanying comment reads
"Nevertheless sometimes I have noticed a strange hissing noise. You can hear a sample when you click on the link below. The noise appears randomly and disappears after I switched the camera off and back on. It appears with no lens attached and continues even after ejecting the SD card. I owned an E-M5 and know that this noise is not the IBIS. I know how that sounds like and the camera produces the IBIS noise as usual when the shutter is half pressed"

I can hear “NOISE 1”: a gentle “wooosh” (= a fan-like noise) from the image stabiliser which starts when the shutter button is pressed and stops moments after it is released. The sound is predicable and very consistent - exactly what I would expect from the IBIS.

HOWEVER, there is another noise which seems more erratic and disconcerting: “NOISE 2” is ‘scratchy’ sounding – like an old modem connecting or an electrical ‘shorting’
I've just been shooting a few frames with my 200mm fd 2.8 on the EM-1 and suddenly realised that what you describe I know as the usual noises I get from the EM-1 and also from my EM-5.

I've no idea exactly what is happening inside but its become so much part of the experience of shooting with this system I hadn't recognised it initially from you description

From my experience, I wouldn't worry about it - nothing has broken yet (it reminds me of the sounds I used to get from my old 300f4LIS, quite comforting really )

Re: E-M1 mystery noise (and battery life) issue

'allo 'allo

I can also hear 2 different noises and my hearing ain't what it use to be.

And I've also noticed the battery drain - both wit new and old batteries. And I've noticed, than when the E-M1 goes to sleep, a slight novement of it brings it back to life - and I'm not activating it wia the EVF sensor. I wonder if it's the level guage. I seem to remember there were an issue with the level guage in the E-3 causing battery drain and that it could be completely turned off to save battery. But can it be turned off in the E-M1??? I haven't figured it out...

I haven't noticed the same issue with the E-M5.

Is my memory failing just like my hearing???

I'm definitely not seeing battery drain on mine, getting much the same life as with the EM-5, anything from 300 to greater than 1000 shots depending on style and set-up

Re: E-M1 mystery noise (and battery life) issue

Get a 'clunck' when I half-press the shutter
For battery saving I have turned the WiFi off
I have also turned the viewfinder sensor off. this allows the big screen to fully power off

Doesn't that leave the EVF on all the time though, think I tried it once. I've got mine set so that the EVF sensor is set on so it turns the EVF on and off but the screen all the time unless I click the LV button.

Must admit I'm only getting about 120-130 images per battery, more or less the same as the E-M5.
I think these cameras are more dependant on power just by being on and not by how many shots you take. I'm a walk around sort of photographer taking single shots and not doing much burst type images.

PS the noise is normal, I believe the general noise is the sensor "floating" and the other noise is the IS coming into play.
