Yeah, I'm aware of the ability to input shutter speed, but you have to choose between shutter speed OR f/s, but you can't do both at the same time, or at least to my knowledge, but that's what Im trying to figure out how to do. I mean the 758c allows you to adjust the shutter angle when on f/s, but of course you lose the shutter angle function when you've adjusted from f/s to shutter speed, but it's not making sense why I can't have f/s and shutter speed at the same time.
