I was setting at my computer and turned around and my grandson was on a mattress so I took a snapshot. It was very difficult to catch him in between moving around. Settings below. This was taken handheld without any support of any kind. This lens is the the version with the stabilization in it, Jeff
NOTE...... This is a snapshot and not a great photograph. The reason I posted it was to show the ability of the lens to shoot at slow shutter speeds.
