So, I am starting to get a bit into event-photography (a few low-key weddings and some conferences) and seeing as I don't think my Olympus Fl36r is safe to put on my 5D3 in terms of voltages (and also wouldn't be a good idea for various other reasons) I need a bit of advice.
I have been using the 600EX-RT on a few paid jobs, but it is a bit out of my price-range for now, and I am not sure that I really need it at all.
For now I am looking at the 430 EX II and the Metz 52 AF-1 seeing as they are priced almost identically in my region. I understand that the Canon might give me more reliability and compatibility whereas the Metz will give me more power and functionality. Still, there are a few things I didn't manage to figure out using google, so I am looking for some who can enlighten me or even someone who has used both.
What are the key differences (apart from USB port and the other things mentioned)
Can the Metz be controlled in-camera like the Canon?
Am I right in assuming that neither model will support all Focus-points for AF-Assist?[size=78%]Is the touch-screen on the Metz as ennoying as it looks? [/size]
