After a short affair with the EF 100-400 during which I was underwhelmed by its sharpness (maybe a bad copy?), the push/pull zoom and its old IS system, I decided to return it and get the new 70-300 L.


It arrived today. While my initial test shots are fantastic (including keepers at 300mm and 1/13s shutter indoors), the barrel that extends has a noticeable wobble. Not a major wobble, but noticeable. The few reviews out there praise the build quality and use terms like "tank" to describe it. But my tank wobbles a bit. Do I have another return in my future, or is this normal?


Thanks for your help.
