[QUOTE="WayneF, post: 229552, member: 12496"] I can't answer about the first one not being sharp. I really don't see much difference, but yes, a little. I can't see the full size original of course, that you saw. If it was black without the flash, then it was not camera shake. The speedlight at 1/16 power should have been around 1/11,000 second, which will handle camera shake. :) However, I cannot resolve the conflict (to me) that ISO 400 f/11 could bounce at 1/16 power. Even it was a lower 8 foot ceiling, f/11 ISO 400 would need closer to full power. And full power is not very fast. The manual says 1/900 second, but there is a quirk. That is measured t.5, which is half power points, the time it is above half power. There is a lot of flash left, so it is slower. A t.1 time would measure 90% of it, and is classically assumed 3x longer, which would only be 1/300 second. However, lower power levels are cut off truncated (no trailing tail), so its about the same number either way. [/QUOTE]
