Question About Canon Camera Lens None
Canon EF 100- 400 IS Lens...

Recently purchased this lens but I noticed when you press the shutter button half way the elements move noticebly, you can see it in the viewfinder and feel the movement through the body. Is this normal. Doesn't happen if you switch off the IS.
