Can anyone give me any advice on flash speeds for this model, I want it as fast as I can possibly get it. High speed flash is far too expensive so just need to see how fast I can get this unit.

Can you be a bit clearer about what you mean by "flash speed". Do you mean the camera synchro speed or the actual duration of the flash?

Generally speaking, unless you have uncontrollable ambient light, the synchro speed is pretty irrelevant as the flash itself is of a very short duration and, in terms of freezing motion, is equivalent to a blisteringly fast shutter speed.

Flash duration (approx.):
1/900 sec. at M1/1 (full) output
1/1600 sec. at M1/2 output

Yes sorry, bit unclear.

Flash duration was what I was after, thanks Steve.

Is here anything on the market that is quicker, 1/40000 sec+ and reasonably cheap?

Not any low cost ones, obviously as the duration reduces, the light output reduces, so getting enough light at faster speeds means bigger or multiple tubes which is going to increase the cost.

Can point you to one that does around 1/100,000 but it costs 2500 - and that doesn't even include a trigger.
