Originally posted by flyer More than likely, your problem is caused by a phantom exposure before and/or after the flash exposure. This is a common occurence when using a flash as fill in with rather bright surrondings and a moving subject.
can you elaborate on this? I can replicate this with my K7 just about any day of the week...
I don't care what people say their camera does or doesn't do, mine does this, and I can't say I think it's a feature!
I've come to the conclusion that it's the combination of SR, flash, high contrast details and maybe a shutter in the suspect 1/60-1/125 range. I could show you a lot more examples but haven't uploaded them. Maybe the flash aspect just highlights what's going on anyway in regard to Falk & Co's research into the bouncing shutter.
I've posted these in another thread, but here goes again...

This shows two distinct images, not a blurred effect camera shake would exhibit.
This was a case of significant ambient light (which is why I used the flash to light the canteen lady) but I've seen it in shots lit by just the flash.
Recently after updating the firmware to the latest incarnation of the latest version, I ran the around the house to test it, hoping is might have been fixed but within the 1st few shots, had replicated it. Over the next few nights I tried again and in about 75 shots couldn't get a 'dud'. The camera had about 3 days left before the warranty ran out and I had a heap of school yearbook pics to take (I still have a K10D I could have used but it has trouble focusing accurately at the best of times) so decided not to take it in. Couple of days later, got a 'dud' when shooting one of the yearbook pics, luckily I zoomed in enough on the LCD to notice it and could reshoot (remembering to turn SR off this time, which returned the desire result).
Guess what I'm saying is, people can suggest to put it on a tripod, turn SR off, focus with live view, stop the world rotating, etc... to prove the camera can take a correct shot (and all that is a useful exercise in itself), but that's not how we always use our cameras, and I can say I've got no confidence in my K7 once I bolt that AF540FGZ on!
