Sync at ANY speed..!

Ok, 1/125 is slow...so.....

I pushed it higher in manual with just the pop up..

No problem shoot at any speed you like, no slow curtain or anything..

After this little success, I tried it with studio lights and a pc lead.

No joy... curtain blackout at anything over 1/125..bummer.

So, I tried it with a radio slave.. same thing.. bummer.

Finally I tried it using the pop up flash to trigger the studio light via a slave...

Fantastic no curtain showing at all at 1/500.....!

Also works if you use a Metz with a peanut slave in the pc lead triggered by the pop up...

Now can anyone explain this, and yes I'm probably breaking the camera's innards...

I flash duration is longer than 1/500 (as it usually is) then light is available during all shutter movement. I think it's rather useless.
