Well I don't have it so I can only go on what I read, but I am sure someone with it will give you first hand answer.

I have been so tempted by Minolta 5D because it has this and from examples I have seen it works. Enabling you to capture sharp images in poor light where otherwise the shutter speed would be too slow to handhold. Also useful if you use a long lens as shutter speeds need to be high then to hand hold.

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
