Hello everyone, I use the Nikon D7200 and recently purchased the Flashpoint Evolv 200 with the Flashpoint R2 Pro N TTL transmitter. I watched a few videos on YouTube where they use high speed sync for their off camera lighting and was trying to do the same. My problem is I’m restricted to 1/320 shutter speed and can’t even change it to anything above that. If I try to go to say 1250 shutter it just doesn’t work. If any of you have used a setup for OCF HSS and can use any shutter speed you want please tell me what you’re using and how to go about it. Any help would be greatly appreciated as I’m getting frustrated as hell. Thank you!
