Magic Drain Pipe with UV Filter Kissing?

Not sure if my eyes are playing tricks on me, but my recently acquired MagicDrainPipe and the Tiffen UV Filter on it seem to be in contact with eachother at the center of the front element. Anybody experience this?

Remove the filter

Enjoy how much better your lens will likely look

Seriously, Tiffen filters are junk anyways, Optically its like shooting through a pane of window glass, id chuck it and get a B+W, Hoya or Kenko

-edit- and beyond that, no i have never had it happen..

I just tried my EF 80-200 f/2.8 L with a Canon, Optex, and a Hoya Super HMC UV filter. They don't quite touch the front element but they certainly are very close. I don't have a Tiffen UV filter in 72mm. The front element comes up extremely close to the filter threads.

Although Tiffen UV filters have the advantage of being inexpensive, fairly tough, and easy to wash, they seem to rob contrast noticeably even when using a hood, worse without. If I look with high magnification into my 58mm Tiffen UV filter, I can see tiny bubbles inside of it. I don't see this in other brands of filters. This would explain the contrast loss.

i've had the same issue with a tiffen UV before "kissing" the front of a ultra-wide a touch. my solution was to take some thread (like clothing thread) and wrap it into the threads of the UV filter. this gives the filter a bit more clearance to prevent the lens from "kissing" the filter. hope this helps.

Tiffen filters make interesting drink coasters....

Don't use any filter, my drainpipe is protected by the lens hood only.
