I know I made a mistake and that the k5 can goto 1/180, if had it on there many of times It was a mistake I made when writing the post.

As for what I was trying to do, I know that its a hack, and that with increased shutter speed's you get decreased flash power as well, but its just something Id like to try and test with my flash's to see if any of them would be any good at overpowering the sun with sync speeds over 1/180.

Why?

To use shallower DoF
To overpower the sun
To have fun and push my stuff to see what It can do.

There have been people using this type of hack on nikon/canon bodys and depending on the flash (some are better than others) can get nicely lit shots at 1/2000 and such. Ofc you are no longer using the strobe as a strobe but more like a continuous light.

I would have loved it if the pc power still triggered a flash with a hss flash enabled on the camera. But sadly after 1/180 nothing gets sent there even in hss mode so It wont trigger my radio trigger.

I need to wait till I get an optical trigger that ignores a pre flash to test my other strobes as the only strobe I have that can do that is my metz af 50. Which btw synced at 1/8000 but wasn't very powerful at these settings.

Don't forget fill in flash for moving subjects! I'd love a sync speed of 1/500th when covering bike runs etc.

Well we can do that with pttl - hhs on camera and off but that wont work with my 400w/s strobes which are manual hence wanting to hack.

I don't get why we cant have the option of doing this in the menu, off by default a and when turning on say that it can over affect image quality over 1/180.

how do you get 1/180th as an option, my K-5 says 1/160 and then 1/200 is the next 'step'....

Use "X" on the mode dial to get 1/180, that's what its for
