This is my firs post, hope its in the right area?... For several years I have been using defective a99s. I call them defective because they don't flash sync at the advertised 1/250s (non-HSS), in fact even at 1/200s there is still a faint shutter shadow. Its not until I slow it down to 1/160s does the "shutter-to-fast" shadow go away. After researching this to be a common problem with the a99 I have just dealt with it. HOWEVER, I just discovered something interesting! I recently acquired a Hasselblad HV which is basically an a99 with an upgraded external makeover with no changes to the internals... Or so I thought. Just for the heck of it I did a shutter/flash speed test and the HV syncs just fine up to 1/250s. So now I wonder if all a99s have the sync problem or is it limited to some. I would think there would be a major recall or more outcry regarding this problem. Strangely the people that have written internet reviews that described this a99 problem don't think it's much of a big deal. If you have an a99 please test it and let me know your results. Again this is without HSS on. I have done tests using the hot shoe, using the PC plug on the side of the camera, with several brands of flash, wireless systems etc.
