Hi, I am considering to buy Metz 52 AF-1 flash (m43 version) to use with my GX7, and wondering if GX7 will be able to do remote TTL with it. I have tried to google the answer, but see some conflicting info. Overall it looks like it will work with the latest firmware on Metz. But before I buy it, have somebody on the forum actually tried this combination? Thanks.
