Good luck with drying it out. If the E-3 was as good as my E-5 I can understand where you are coming from in this weather.

Re: Come back E-3, all is forgiven.

Thanks for all the replies and advice, guys.

It seems to be OK this morning, after a shaky start. When I first turned it on the camera instantly focused itself and took a shot. It repeated this behaviour every time I turned it off, then on again. After the camera had taken this unintended initial shot, I found the half-press function of the shutter button didn't work - a half press focussed and took the shot, rather than just locking focus.

I've now got it functioning as it should, after "working in" the button by continually pressing it in single shot mode and holding it down for long bursts in drive mode. I reckon there was still a bit of moisture lingering under the shutter button.

I'm very relieved that it's now working, but it does mean that I can never trust this camera again if there is even a hint of rain or snow.

Re: Come back E-3, all is forgiven.

That's a shame - weather sealing was one of the things that almost made me get an EM5 rather than an EM10...

On the other hand, my EM10 survived 40 minutes in pretty soggy rain as I walked through London the other day - no probs at all.

Re: Come back E-3, all is forgiven.

I'm also pleased to read that it's back to normal-ish!
The half press instant picture capture is a menu option, isn't it. Have you done a Ctr-alt-del on the camera, might be worth doing.

Anyone who has worked in the aerospace industry will know the design objective of keeping equipment boxes water tight and letting them breath are at odds with each other. Seal completely and the box will attempt to inflate and deflate with change in at pressure, even if you don't fly we have quite a wide range of pressure changes in the UK - 1936mb (Stornaway 2013) to 1030 or higher - which will stress the seals, possibly to failure. Take your camera flying and you and your equipment will see even wider variation. (Admittedly military aircraft see a higher rate of change than civil aircraft, but commercial A/C have to design for projected extremes, such as rapid decompression.) The solution often in aerospace it to let the equipment breath with drain holes and to conformally coat the electronics (conformal coat is similar to varnish but chemically compatible with circuits).

So, I'm left wondering how 'consumer' grade cameras can claim to be weather sealed. It's remarkable if the claim is true, given the competing design objectives outlined.

I suppose the answer is that a seal can be watertight without neccesarily being airtight?

I suspect my problem may have been caused by an internal seal failure, the camera should have handled the conditions yesterday without any issues.

The above bolded sentence also describes what happens when the HLD-6 battery grip is attached with the switch in Locked position & when the grip's landscape button is pressed inadvertently. It shouldn't, but it does (just like the E3 & E30 with HLD-4 grip). BTW, the E-M1 & HLD-7 doesn't have this problem as it has been addressed.

Back to your issue John, if there was moisture shorting the camera's connector pins in the base (for the grip), maybe that could have been the cause too.

Re: Come back E-3, all is forgiven.

No I don't think so, the 'needs' are mutually incompatible. True, water droplets have surface tension which may resist slight 'give' in the seal, but water could enter by capillary action. Apart from that, variation in humidity could be a killer if not completely sealed, or if it's not sealed by design and the the circuits are not protected with conformal coat.

Do you think it's worth you doing a general reset?

I really wouldn't think so if it is just electrical shorting occurring at the shutter button or associated connectors (USB & battery grip connection point). It may need it if other odd behaviours continue perhaps, but if it is now working OK, then I wouldn't.

Re: Come back E-3, all is forgiven.

Glad to hear you have your camera back John, with regards to the non confidence regarding sealing, Oly can assess and quote you for a repair, they changed a seal and cleaned my 50-200swd for 60
which I thought was a great price, worth a thought...

Glad to hear that an over night dry out has your camera back up and working.

I wonder if the weather caused the seals to shrink a little in the cold and let some moisture in. An excuse to get an EM-5 Mark II?

I hadn't considered that the problem might be with the grip connector pins on the baseplate. It's certainly something to check if the fault repeats itself.

I was thinking of doing a general reset but as it now seems to be back to normal and working OK I'm inclined to leave well alone.

Re: Come back E-3, all is forgiven.

Having used my E-410 in rain, snow and at -20C without a problem I'd suggest a British Rail explanation that it was the wrong type of snow.

In the future I'd treat it as an unsealed camera and keep it under your coat between shots.

Yes, it's a good thought, Cliff, but I'm in two minds. I don't know for sure that it is a seal for the shutter button, that's just my best guess, so I could pay out 60 or so and be without my camera for a couple of weeks and still not prevent the problem from happening again. In some ways it might have been better if the camera had not recovered; that way the repair centre could have identified exactly what caused the problem.
