Canon 55-250mm IS making a funny noise

[tommedley]

I have just bought this lens. It's the first lens I've bought other than the kit lens that came with my 500D. When using IS with the lens, it makes a number of weird noises that I don't get on my other lens. Is this normal? It appears to work ok but I've only had it a day, not proficient enough with it yet to really tell.

It should make a slight high-pitched whistling noise when the IS is activated. That's normal.
