I haven't seen anything other than the 1/180 sync speed spec, so I was hoping to see if anyone at Photokina had tested or asked about speeds faster than that (unofficially).
That is, on other cameras, either the hotshoe x-contact or pc sync port is still activated at faster than x-sync speeds, allowing you to cheat the official sync speed. For example, at 1/300 you might still be able to get 3/4 of the entire frame synced with flash, allowing you to crop in. This wouldn't be that bad a compromise with the higher resolution now. On all the recent Pentax models, I have noticed that the flash contacts are de-activated once you are faster than 1/180.
This was one of the hopes that I had with the firmware hack projects that were being developed (e.g. focus adjustments). Any more word on this from anyone?
Thanks!
P.S. Please refrain from the constant questions about why this might be necessary or "just use HSS." It's not just for higher shutter speeds for action. A higher sync speed allows for easier balanced daylight with flash shots, for example, without having to resort to HSS which drastically reduces effective flash power (e.g. working distance and/or aperture flexibility). If you don't understand why this may be relevant/desired, check out strobist type sites for examples.
