Mongoose, I'm not really into electronics but your idea might work though.
I might even get a second Cactus trigger and convert that to a wireless camera trigger maybe, don't know if you can do that?
Other option would be screwing around in the firmware, I was actually planning to do this. Already looked into the firmware once but it's still an nightmare.

Normally it wouldn't trigger on 1/200 either but by change I came across this little trick.
I was hoping I could use the flash in HSS and set the shutterspeed on a higher speed and then remove the flash and use the Cactus to trigger it but that didn't work

I wonder when the first camera with something like environment capturing technology might come so that you can recreate the environment of the photo so that you can smell the salt air of the sea for example.

Stefan,
Well, it's not really going to help you that much anyway
1/180 to 1/200 isn't even half a stop, and 1/180 to 1/250 is, what, half a stop?
For what you want to achieve, your best option is an ND filter (apart from another flash)
Matt
ND filter would also Harm the flash light so that isn't on option either.

Straight out of the camera JPG with EXIF intact.
Af540 and Cactus v4 wireless trigger.
I just see I should have focused a bit better

I once also had the idea but the AF540 is just to heavy like you said and I was getting used to it by holding the flash in one hand and the camera in the other and simply use the pop-up flash to trigger the AF540 wirelessly.
I wonder if a simple flash stand might not be easier, something like a gorilla pod maybe?

It's simply misses the stop-down aperture lever, so it's less compatible with non auto aperture lenses.

But what's the point? A flash is much shorter than the shutter anyway, so unless your ambient light is very strong compared to the flash, the flash will be your main source of light.
Typically, flash duration is less than 1/1000 s, and on low power even shorter.
You can of course also lower the ISO or use a higher f-number but the problem is you then also need more flash power and that's sometimes limited.
Stefan,
You can't get a higher sync speed
HSS is not a 'trick' - it's a necessity.
1/180s is the faster speed at which the leading and trailing curtains of the shutter are both open, exposing the whole of the sensor to the effect of the flash.
When the shutter speed is faster than 1/180s, the trailing curtain will start moving before the leading curtain has finished its travel. If the flash were to go off for such faster speeds then you'd only get a tiny bit of the frame exposed by flash - the rest would be black!
I've shots taken with 1/200 flash sync on the K10D so you can go faster than 1/180
If you've a P-TTl flash and a manual flash you can do it and of the 20 shots i've taken non had a shutter on it so I wonder how far you can go.
If you can get 1/250 Pentax would be in par with many of the rest of the camera's and who knows how far it might go.
The *ist-D could do Wireless HSS with the pop-up... but then it didn't have SR. IIRC, the current SR-equipped bodies can't do wireless HSS with the pop-up because of some power supply issues.
If you have TWO AF360/540 guns you can do wireless HSS
ps. I'll make a photo and upload it so that you can see that it goes down to 1/200, still haven't find a way to get the trigger to work at faster speeds
