I have attached a link to a couple of photos which (if the link works) will show the sort of image that we get in lower temperatures, together with an image taken after the battery was taken out & in again.

Have tried different, high quality, SD cards. They each have the same problem. Also, it has had the latest firmware upgrade.

It does seem to be something to do with the battery because it works if you take the battery out and put it back in again. If it is a condensation problem then I thought they were supposed to be 'weatherproof'. Even the SD cards are sold as not being affected by condensation.

Pentax want my husband to return it to them with all of the lenses (he bought a couple of them that cost about as much as the camera). I don't see why they need the lenses as it happens whichever lens is on the camera.

He is very reluctant to post it to them, even with insurance, because of the value. He can't find the receipt which they say has to be sent with it. I came across this forum and thought that I might get a few ideas on how to solve it for him.

Thanks for everyone's advice. Guess we are going to have a long drive to Pentax UK if he doesn't want to post it. Even though someone said it is only meant to go down to 0 degrees, obviously most people seem to get it to work ok much lower than this.

It was a Pentax P30 that took the brilliant pictures in Peru, and it is a shame that we converted to digital.

Thanks John,

He has a lowepro slingshot bag that I got him for Christmas, so hopefully he can get the camera packed away much quicker than his old bag (not me).

Didn't realise that it only went to 0 degrees though. With the way the weather is going we won't be able to use it for several months a year! No worry about ever reaching 40 degrees though, as they get the 'barbecue summer' wrong each year.

Oh for the days of film again then, because he has shots high up in the Andes and the top of Mount Kenya. Our bodies may be beyond that nowadays, but we expected a camera body to still work in the same way.

Can anyone help me? My husband bought a K20D and whenever the temperature gets into the low centegrade, but still above freezing, it just gives pink hash as images. If we take the battery out and replace it then it works ok again, but this is a real pain. It was marketed as semi-professional for the ambitious user, but he is regretting not keeping his old P30 and using film if this is going to happen each time.
