Hey guys, I currently have no good flash and probably won't invest in one the next few months, but there are a few things that make me curious for a while now so I'd like to ask some noobish questions. 1. The "new" hotshoe Sony uses now - does TTL metering now also work on other non-Sony flashes? If not, what are the options for TTL - only the expensive HVL-F60M OR a iISO-hotshoe flash with the bulky (in NEX terms) adapter? 2. (Wireless) flash syncing: What are the basic options? Do all flashes have to be from the same manufacturer (e.g. a Sony flash can only trigger other Sony flashes, a Metz flash can only trigger Metz flashes etc.)? So I can't combine for example one Sony HVL-F43AM and two Metz flashes? 3. How well can the power output be regulated on modern flashes like the HVL-F43AM? I want to know this especially because I'll need two off-camera flashes for macro photography and I'm not willing to invest in Sony's expensive twin flashes - after all, 700€ is too much for a pair of GN 20 flashes. 4. What flash system would you recommend for the future Sony NEX system (e.g. with the standard hotshoe) and why? Thanks for your help! And again, I don't need advice in the artistic use of flashes - I have a bit of lighting background from my video work (with 500 - 1000W 5400K lights) and I watched quite a few flash tutorials - but neither of them explained these technical basics, so please help a poor photographer with his dummie questions.
