DA 21 Filter...OK whats the secret?

I really dont want to be asking this question (shows up my ignorance)....but I give up. Whats the secret with attaching the 43 mm filter to the DA 21 Ltd?

The Filter is a Hoya CPL 43mm, pitch 0.75.

I have removed the hood and screwed in the filter (several times!!) but now the hood will not click back on the lens. The back of the filter protrudes out the back of the hood a smidge....?...which looks to me as being just enough to prevent the hood locking back in.

Any clues..?

ahh only a UV (protective) filter works that way.. For CPL you should buy a 49mm one (not 43mm) and remove the hood and screw it on to the lens.. CPL would be useless under the hood as you couldn't turn it to get the right setting for the CPL..

You won't be able to reattach the hood though a cheap 49mm rubber screw in wide angle lens hood would be a good option...

I gave up on 43mm filters. Got myself some 49mm filters and a sweet metal B+W hood, which looks awesome.

Why? Spend $4 for a 49-43 step-down ring adapter and enjoy your new CPL.
