SDQ and SDQ-H shut down

[Roger]

Greetings Sigma People

Ya, I was out shooting in a snow storm yesterday and the temp. was 28 degrees Fahrenheit -2.2 degrees Celsius and yes they quit, dead, EVF, and LCD went crazy on both the H and the Q and other weird things went on as well, then the batteries went out. Good news, after about an hour in a warm car they came back, sort of, good enough. Bad news they lasted about 30 minutes then went out again.

What to do now???

Good news, my SD1 and SD15 worked fine. Or as fine as the SD1 could work. SD15 is perfect.

What to do with the SDQ and H????? Wonder how they will work in temps of 100 plus degrees???

Sorry to hear about all that, Roger.

I've read of people keeping their batteries inside the big Winter coat, almost next to the skin, but it wasn't quite clear to me that the batteries were the problem especially at a mere 28F !

Good news, my SD1 and SD15 worked fine. Or as fine as the SD1 could work. SD15 is perfect.

Glad to hear that (from my POV) - since I've recently replaced the SD1M with a SD15.

What to do with the SDQ and H?????

Only thing I could offer there is English sarcasm, which you wouldn't appreciate right now I'm sure.

Wonder how they will work in temps of 100 plus degrees???

Sorry, I've read here that they shut down with a high temperature alarm, IIRC.

Similar issues here.

Best I can say is to email Sigma.

Roger,

Sorry to read that. Were you out in the cold for a long time and how soon after being in the cold did the shut down happen.

I think you should prepare a very detailed statement of what happened and email it to [email protected]

Even if it is a phenomenon can not be easily dealt in the current models it is something that should be kept in mind by them for future ones.

I live in the Philippines and it is generally quite warm. (Note: Understatement...) Meanwhile, on warm (90F degrees plus) days, using the lcd, the camera quickly starts to show the overheating warning sign (the thermometer image). It's not so bad if the camera is kept off and then turned on for an image. Or if the LCD is turned off. But it seems like the bottom line is that the internal electronics run pretty warm.

The usual daily temperature here is about 85F, so it isn't a constant thing, but the camera will overheat. The good news is that the nights are wonderfully pleasant, and the natives generally friendly.

I know other parts of the Philippines and the tropics are both warmer (farther south) and cooler (the inland hills and mountains, and rainforests). Almost all the island I am on (Cebu) is near the ocean, so that helps. It's a warm place.

Richard,

So as well as the cold "shut down" the overheating also needs to be dealt with in the current sdQs, if possible, but certainly in any future models.

Maybe you should report your overheating details to [email protected]

I do not have the problems of heat or cold because temperatures here vary between around -3 or 4C in the Winter and no more than about 25C Max. in the Summer.

The sdQ runs much warmer than other mirrorless cameras probably due to the heavy processing required for the Foveon three layer sensor. I turn mine off between shooting sessions to keep it cool.

In cold weather any camera may just suddenly shut down as the batteries stop providing enough current.

It sounds like it shut down and then you tried to turn them on again, leading to the issue recently discussed where in cold weather it may turn on into kind of a garbled screen due to something in the 1.07 update - if you see that turn in off and on again several times and it should work.

However with a flat battery due to cold it may not come back on again - if a camera shuts down due to cold I put in a fresh battery and put the other back in my pocket to warm up. Then after a half hour or so it will probably work for a while again.

Another solution I find helpful in cold is to use the external battery pack. Since it can draw from all three batteries at the same time it doesn't matter if the power output dips a bit from each battery..

Works fine for me. I had a camera thermal shutdown just once, when I left the camera out in the sun for a while on a very hot (110F) day. Keep any all-black camera out of direct sun if you can. Maybe that's why Canon makes lenses white.

all the batteries do that when it's cold. using socks with hand-warmers in it and switch often is the normal practice, with any battery when it's cold.

But then the SD1 only had one processor.

Looks like you were short-changed, Jim. Mine had two of them:

" Dedicated Dual TRUE II image processing engine A dual configuration of Sigma's renowned TRUE* II image processing engine powers the SD1 Merrill, bringing out the full potential of information captured by the full color sensor"

From the SD1 Merrill brochure ...

In my understanding, one of the "known issues" with the Q cameras is the heat from the processor. That heat issue is a concern anytime "full frame" discussions come up. It is a beautiful camera, in terms of design and construction, in my view, but... It would seem to need a better way to deal with that heat. As it is, it is sealed up tight, as is the current fashion, and there is nothing resembling airflow near the processors. In any event, although I have seen the warning many times, I have beautiful images of where I live and I've never had it actually shut down from the heat.

With my limited technical knowledge cranked up to max, Richard, it all comes down to the design of the heat sink and the space for it to be located as close to the outside as possible.

I hate to butt heads, Jim, but do you know for sure that there are any heat sinks in the Q cameras? I ask because you mention "the heat sink" as if it actually exists.

As to locating equipment closer to the walls of an assembly, a slight improvement might be gained by radiation, but the main factors remain as convection and conduction.

Sorry.

OK, could be a language problem.

"it all comes down to the design of the heat sink" . . is there one or not?
