OK, four more test photos, not everything that was asked for, but all I had time for today. These were all taken after a complete factory settings reset, shot at full 300mm zoom, full camera auto-focus, using a central point. Images cropped to roughly 1200x900. Auto-IBIS on, as it is by default, single drive mode, no anti-shock.
Pic #1 was a full iAuto hand-held, of a hydrant out my car window while waiting for a train. 1/250, f6.7, ISO640. Train was done before I had a chance to try more. :( Quite Blurry.
Pic #2 was a full iAuto hand-held, of a Goose about 30' away, moving very slowly. 1/250, f6.7, ISO400. Quite Blurry.
Pic #3 was speed priority, hand-held, of a Goose, again moving very slowly. 1/1000, f7.1, ISO1600. Better than #2.
Pic #4 was a full iAuto tripod shot, indoors, of one of my kids toy birds, using remote shutter from O.I. Share on my phone. 1/13, f6.7, ISO1600. I did take a hand-held shot, but due to the very low speed, it was obviously very blurry, so didn't attach it here.
So, Pic #1 is similar to my first iAuto shots with this camera, quite blurry. Increasing the speed to 1/1000 made a much more clear shot, so it would appear the blur is hand shake related. At 300mm, 1/250s, I would have expected IBIS to handle this for a more crisp shot. Have I simply run up against the limits of IBIS?
I need to do tripod testing during the day, when I can get shutter speeds up to typical outdoor shots.
