17-40 internal zoom issue

I recently bought a new 17-40mm L and have noticed that the front element physically contacts the filter (tiffen UV) when the lens is zoomed to 40mm. Is this an issue with the lens itself, or would a slimline filter fix the problem?

Hi James,

I just checked my 17-40 with a B+W filter on it and the front element does not hit the filter.

I'm not sure what may be wrong with your setup, but I'm guessing it is a problem with your lens, not the filter. I may be wrong though.

Maybe try another filter.
