Has anyone tried to figure out the delay between pushing the button on a wired remote trigger to actual shutter release? I have a Alpha-57. I want to try taking freezing objects in motion - not very fast, think of the speed of a ball dropping.
I took a wired remote, added an opto-relay that I can trigger from a optical sensor. The sensor has a <2 ms delay, the opto relay is << 1ms. But the ball is already out of the frame when the picture is taken. I'm using 1/200 shutter priority, a lot of constant light and manual focus.
Is there anything I can do to speed up the response? Or would I be better going to a long exposure time and using an external strobe in a dark room?
