In this case the problem is not caused from movement of the sobject, but it is more likely caused by a double exposure, the first caused by flash light and the second formed by ambient light. You can solve this problem closing diafragm. If you want to keep lens open and flash light you can chose HSS or a ND filter.paul13walnut5 said:hyles said:Usually flash is faster then any shutter speed, and it is flash light that freezes the movement.

True in a studio. Not so true for fill flash on bright summers days.

Yongnuo are pretty well praised, I have a Sigma with HSS, and it works great (other than the firmware being glitchy) I can shoot @ f 1.8 in the snow and still use fill-flash, although the 61 meter range is cut about in half.

A secondhand 550EX is better value and will always have 100% functionality with any EOS camera now and in the future.

I've got 2 YN-560's, and I wouldn't have a problem buying a HSS version. That company is still trying to shake the QC reputation of some of their first production runs. I just haven't had a problem with mine after two years.
privatebydesign said:Leaf shutters have their own issues. People that think they give true sync at high speeds don't understand how they work. They are not a panacea they are an effective second aperture.
privatebydesign said:This series of videos gives a best case scenario, and aptly demonstrates that leaf shutters act as second apertures at high sync speeds.

Remember three things, first, the X100S is designed from the word go to do this, and it fakes it somewhat by not energising the sensor for the first half of the shutter travel (effectively it has an electronic first curtain), any camera not designed with an electronic first or second curtain can't get close to this efficiency; second, when a leaf shutter acts as a second aperture you lose flash power; third, your flash t1 times become critical, don't think about using a small flash at full power because it isn't fast enough to get the light out there, studio strobes are very slow, with some t1 times as slow as 1/60 second.
Of course there are options to get light out at high speeds, but they all cost good money, even Einsteins aren't cheap if you have to gang them because they only do a full power t1 of 1/666. A leaf shutter is not a panacea to high speed sync issues.
