Last year I was in Yosemite Valley on a day with the temperature
dropping below 32F (rain turned to snow). I had been carrying my
Olympus D-490 in a camera bag under my Jacket. I took it out and took
one picture then went to close the lens cover / shut it off. The lens
wouldn't retract. I put it back under my jacket and was eventually able
to get it to retract. I don't know if it was the camera or the
batteries. After that I either didn't take some shots or kept the
camera under my jacket to open / close it and just pulled it out quickly
for the shot.

Not sure what the problem was, but there is no way the cold could
have affected the batteries in the time you took it out, took a picture
then when to close it back up. Those batteries have a fair amount
of thermal mass and they are enclosed in the camera when the door
is shut so it would take quite a while for them to change temperature
based on the ambient temperature. I have a D-490 and have not seen
any problems like that and have had it up on the ski slopes a couple
of times (in my jacket before/after taking the pictures) with no
problems.


Thanks, it's good to have additional data for the same camera.

It still could be the cold, I was darn cold. It's possible the
batteries were marginal, I don't recall if I needed to replace them
later.

NIMH batteries that are cold do not deliver all their charge, but will
deliver the rest of it when they warm up.

Really!I didn't know that.On the other hand, I shot with my FM-2 while
skiing, and its Lithium battery (used only for photometry)worked perfectly.I
don't know what happens with the Nicd batteries I bought for my current
Kodak CX 7300.(No money left for the more expensive NiMH batteries).

More expensive? A pack of 4 NIMH batteries goes for about $10US around
here. That's too expensive for batteries that will last for 300-500
recharges? At only 100 pictures/charge, that would be 30000 pictures,
at least! Expensive???
