Problems with a99
« on: December 31, 2012, 10:32:00 AM »
I am on my way back home last night in Kenya but the first day using the a99 the camera after about 300 shots freeze. I couldn't beleive it brand new camera and to shows already problems.

I tryed turning the camera on/off but the camera didnt react. The recording lamb inndicator was on so i decited to remove the battery and then the camera started again
After that in a few days
later after shooting lots of shot i let the camera to go to sleep mode and the wouldn't wake up, so i hat to remove and reinstall the battery.

Affer that days the camera worked ok with no problem

Is it possible that the sensor is overheated? Sony warns about it, especially when shooting videos for long time, but can it happen when shooting stils?!

Manual says about some warning sign when it is overheated ... I'll check that one ...

Hi Rex,

When internal temperature is high, the camera should give a following warning message:

Internal temp. hihg. Allow it to cool.

- The camera has become hot because you have been shooting continuously
Turn the power off. Cool the camera and wait until the camera is ready to shoot again.

Just out of interest, what are the min / max operating temps of the 99?

I was reading a blog written by a member of the British Antarctic Survey who was shooting with a 77 and a 99 and he did not mention any issues..

Dave, this is from the manual:

Your camera is designed for use under the temperatures between 0°C
and 40°C (32°F and 104°F). Shooting in extremely cold or hot places that exceed this range is not recommended.

I quess it is pretty much the same as with a77.

I have used a900 in -35 celsius and a99 in -20 celsius. At summer time we seldom get over +25 celsius ... Half of the year we have temperature below 0 celsius so for me the designed temperature is a ... joke ;)

Rex, I assume letting the camera over-heat must has caused the issue. So far no problems on my side with either the A99 nor the A77. I had the A77 out in -9 degrees celcius without a glitch.
Hope it gets sorted.

I think when Sony specifies these Min/Max temperatures they mean not to allow the cameras innards to get to these temperatures. In real life scenarios the camera will never go so low or high as the user would surely suffer first and get himself into warmer/cooler temperatures, unless he died first. :(

I generally agree withyou Ascot, but the camera was left in the car on the back seat in the sun and that could have easily caused it. I would phone Sony and ask them whether this might have been the problem.

41 celcius predicted here tomorrow - the first really hot day of our summer so no walking around in the sun just in case the camera does not like it :grin:
Hopefully it was just overheating Rex

If it is a Camera problem it will appear again, if it was overheating then i Will realise this again when our summer comes where the
temperatures vary from 35~45 C

I think you are most likely to find it is overheating, especially as you left it in a car. There have been many reports of the A77 and now the A99 overheating, most often when using the movie mode. They advise, "do not film for longer than 30 minutes without letting it cool down". It does not require high outdoor temperatures, it can happen indoors in air conditioning.
