We are having thunderstorms intermittently today but there was a brief gap in the weather with really nice light so I took some ISO 1600 shots with the 7d MKII.

I added 1 stop of light to most of them to prevent any chance of under exposure and I also down loaded the version of DPP that came with the camera. I found out it handles the noise better than Adobe Camera Raw

This is a full frame image. The light was very good as you can see from the shutter speed. I could have shot this at ISO 400 and 1/500 sec but I believe the very high shutter speed really helps to produce sharp images of birds especially with this camera.
