Hello David,
thank you so much for your reply, I really appreciate that. I will do my best to generate a TTL pulse, never did that, but it seems to be possible with an Arduino. The flash system I use is a special one being able to fire at speeds up to 4k and more, I hope. I'll start testing this weekend, I suppose.
If you don't mind to help me with my first question I had here in the thread? I am a little bit concerned at the moment. The more I dig into the lens topic, the more I get the feeling that I won't be able to mount a focal length that delivers a FOV equivalent of a 28mm fullframe lens? Might that be true? I need to have these 28mm.
Thanks a lot again!
