John sent me this:
I just got an email from the Chinese company MX Camera who sought startup funding through Indiegogo for their Owl drop in filter adapters for Canon, Nikon, and M43. I paid for 1 adapter but haven’t heard anything since March so I assumed the money was gone. Now they are asking for $25 dollars for shipping. I’ll bite the bullet and see if it’s just a fishing scam or the real thing.
Full info on the adapter on that 43rumors post.
