Re: Reasons for fogging

Boy, I've certainly opened up a can of worms.

Nah, we're just having fun

To JEFFTAN I've not had many failures to focus in low light on the TG-2, but I have had some on the 820. I think it's normal for some focus misses in low light, you need to either focus on areas of changing contrast or pre-focus on a subject at a similar distance (of course light levels have to be the same to get correct exposure so you might as well stay with what you were trying to capture in the first place).

I find that "failure to focus in low light" usually means that the battery is starting to run low.  (Another frequent reason is that I left "Macro" on by mistake).  One workaround is to turn off the AF entirely - for example, use the "underwater snapshot 2" mode, that focuses the lens at the hyperfocal distance.

To AYCL Taking underwater shots so far here in Perth I have not had any fogging of lens/lcd. But I think it's important to note that the temperature here is nothing like that in Thailand where I was using my first TG-2.

You have to take into account both the water temperature and the humidity of the air trapped inside the camera.  The worst scenario is to let the warm and moist air into the camera, then close it and cool it down.

It's been mentioned several time about the "anti-fog coating on FT5 lens". I think this coating is on the outside of the lens the same that is on the TG-2 to stop water droplets forming on the lens when it's taken out of the water.

That's what I think, too.

Re my first TG-2 fogging, I read somewhere (don't you hate it when you can't remember where you read it) that the battery heats up when the camera is used and this can raise the internal temperature of the camera which can lead to temperature differences between the inside and the outside of the camera, thus condensation forming inside.

The heat from the battery would actually reduce the problem.  The condensation forms as the air trapped inside the body gets cooled below the dew point temperature.  If the heat from the battery could keep it above that point, you'd get no fogging.

If I get this problem again on my TG-2 I'm going to give it to the kids to play with and I'll go back to the 820 (never had any fogging probs). Thanks all

I doubt that the exact camera model has much effect on the fogging.  It would be interesting to do an experiment - hold both cameras open for a while (to make sure they have the same dew point temperature), then gradually cool both of them down, and see if one fogs up at a lower temperature than the other.  My prediction - they'll both fog down at exactly the same temperature, though the body with more plastic (810) may take a bit longer to cool down than the body with more metal (TG-2).
