Thanks Loupey. I don't think Olympus has telephoto lenses of more than 300mm considering that the crop factor for all Olympus DSLR's is x2 which makes it 600mm equiv. I have the 70-300mm and the IS system works beautifully. Here are some examples:

However, I was unable to obtain the same results by shooting in dim lighting handheld at 1/5 by Canon nor Nikon lenses.
