Well bit of a surprise. After printing (side by side 5x7's, photo glossy paper, i960) the difference in brightness vanishes and the 2 pics look like the proverbial peas. After close study however, the lunar seas show a wee bit more contrast in the DZ's!

This suggests - to me at least - that Panasonic is doing something in-camera to improve DZ quality.

Hey Bobc,
Why did you turn your IS off?

It's recommended when using a tripod to turn it off or set it to mode2. I turn it off.

Im no pro but that doesnt seem to make a lot of sence to me. What is the advantage of turning it off? When I try to take photos of the moon even with a tripod and timer without the IS the images dont turn out.
Where did you read that you are surpose to turn if off Bobc?

I don't understand it either but it says on page 76 of the manual .

"OFF - ... when using the camera with a tripod."

Guess it has to do with IS not working with slow shutter speed and dark conditions, that would be a tripod shot definately.

My guess it it's to preserve battery life. If the camera is mounted on a tripod, there's no need for IS, so why waste the juice?

I read it in this review.

It also says it in the manual on page 76.

I am guessing that if it is on. It is expecting to adjust for jitter. And if using a tripod and no jitter is present, it may be trying to adjust for something that is not there. Thus perhaps causing jitter.

Just guessing.

Hey that makes sense, if I think about it that way!

The camera is already still but if the internal stuff is moving to compensate for a motion that isn't there it would/could cause some unintentional motion.

The thing called O.I.S by Panasonic is a giroscope attached to the lens system mounted on the camera.

When you halfpress the shutter button,the giroscope is locked on that position, if you move the camera, the giroscope+lens willstay on the locked position. If you move the camera too much, the giroscope won´t compensate that movement so it will lock on a new position.

MODE1: the giroscope is locked all the time.

MODE2: the giroscope is locked when you halfpress the shutter button.

This is how I think it works.

On this link you´ll find some info about the IS system: http://panasonic.co.jp/pavc/global/l...0/megaois.html
