There should be EXIF data with all of these. All were taken with either the 55-300 or the 70-200 VR II. Surprisingly, the ones taken with the 70-200 are considerably sharper. All were taken between ISO 200 and 12,800.
SECOND EDIT: This post is an absolute disaster. My relatively new MAC has me technology challenged, so when I checked it out on my PC today at work, I realized that half of the images do not show the ISO info so I am deleting most of them and just leaving the ones that line up with my other post. Sorry for the mess.
Edit: The only reason that I posted these was because I was amazed at the high ISO capabilities of this little camera, but I now realize that you can't really enlarge these tiny jpegs so I am including crops of some of these in a second post.
