filter partially blocking extension of hood

[msheppler]

I recently purchased an APO Summicron - M 90 ASPH from a fellow member. It's a beautiful lens. I bought a B & W UV Haze filter and after I mounted it the hood will not fully extend.

Any thoughts would be appreciated.

Go back to the dealer and ask to try other version of the same mm filter. You may need a thinner profile.
