Nope, none at all - just did a quick test @ 50mm with an even deeper hood - 2.5" deep, 2.5" diameter. Tomorrow I'll try longer and narrower. I think there's still room for improvement as the hood I'm using works well even on a 35mm lens. At some point the hood will become ugly, unwieldily, or vignette, but it's got a way to go on vignetting.
