Does anyone know what the reason may be that even the newest announced e-mount camera's flash sync speed is only 1/160 s?
Is it not possible to improve upon that with a mirror less camera for some reason or do just too few customers care for it to be faster?

I shot an outdoor wedding yesterday for a friend and used an Opteka TTL for fill flash. The more I use my NEX-7 or 5N the more I realize that flash logic and shutter limitations are a serious downfall for Sony.

1/160th max shutter speed is way too slow. Fill flash on a sunny day is going to give you major blown highlights. There is no way around it as far as I know unless you go with a manual flash. The Opteka can't be blamed since even the pop up flash on the NEX-7 will limit any mode to a max 1/160th shutter speed.

Even if using a manual non TTL flash you are limited by the shutter capabilities which will beginning clip the flash exposure top and bottom of the frame at 1/250th and faster shutter speeds.

I really don't know how pros using Sony equipment get around this problem. I thought about using an ND filter but am not sure if that would have messed with the flash logic.

Any ideas from pros of how to deal with fill flash when using Sony cameras in outdoor settings would be greatly appreciated. I shot at F/8 but didn't want to use a smaller aperture for fear of diffraction. In the meantime I have some seriously overexposed images to fix in LR.
