Lensmate Adapter vs Olympus CLA-12 adapter?

Hi. I'm interested in experimenting with a polarizer filter when shooting landscapes(lakes, beaches etc) with my XZ-1. I'd prefer the Lensmate, but it looks like these are out of stock, and with the impending release of the XZ-2 I'm wondering if Lensmate will even produce these anymore? I notice the XZ-1 camera is not listed in their product menu, I had to find the XZ-1 accessories page through a Google search.
I tried emailing them-we'll see if they respond.

In the mean time, does anyone here use the Olympus CLA-12 adapter with filters? Looks like it's 55 instead of the 52mm of Lensmate-any other differences? Mainly, are you able to fully extend zoom with the CLA-12 + filter mounted?
Many thanks!
