Originally posted by K-3-lover If your shot is critical for the delay, you had better using a binocular to see the timing and then tap the shutter button on the phone. You may eliminate the delay of the video transmission for the live view.
I could see the timing from my window, but not the framing. I had the camera with a 50mm macro lens right in front of the feeder for a tight shot. The birds got used to it, and were even curious. If it had worked, it would have been impressive.
Not all the delay is in the video. I tried a wider shot while watching and using an RF remote shutter release I already had. There was some delay from pressing that button, too. It was not noticeable until I was framing a darting animal.
