Last week, I experimented with the OIS app on my iPad to capture birds at the feeder. Once I figured that out, it was time to add a branch and make things more natural. I also rented a Panasonic 100-300 for the weekend. These are at 150mm on a tripod with all image stabilization turned off. Focusing is done remotely, and the app is great in that it also lets you change ISO, white balance, etc. all from the iPad without walking up to the camera.
