In-Body Image Stabilization is a system that reduces "camera shake." It is increasingly more popular than in-lens stabilization schemes (IS, OIS, VR, VC, etc.), because if it is in the camera body, it works with all your lenses. Some manufacturers have "Dual IS" or something similar, that combines in-lens and in-body stabilization schemes.

The net result is that you can photograph at slower shutter speeds without worrying about CAMERA motion blur. Of course it does nothing for SUBJECT motion blur, which is controlled by shutter speed or flash speed.

Nice images Sue. Hanging Lake has to be the most beautiful scene I've ever seen! My wife & I hiked up that 'path' many years ago before the incline pathway was improved. We had our three children with us and it took half a day to make the climb, but it was totally worth it! This was back in late 1960's. Then, there was a very simple small wood sign like an arrow, with "Hanging Lake" painted on it by this roadside rest area we pulled into. I understand now it's pretty commercialized compared to back then. I thought, 'This must be how the Garden of Eden' must have looked, when I first saw it. They explained that the boardwalk was brought there by Helicopters and a Boy Scout group did the work. Thanks for posting that picture. Brought back many happy memories!
God Bless
