Just wondering if anyone has tried the Raynox HD-6600PRO-46. I know there's a lot of information on the Panasonic but I've not much on the Raynox other than video or macro. Also the Panasonic is "suppose" to be paired with the 14mm or 14-42x. But is there really any reason not to use it on anything with a 46mm thread? I mean there're so many Panasonic, Olympus, and Sigma primes with 46mm threads.
