N.B., HSS is not really suitable for anything moving fast.
It's good enough for everything that the FP shutter is good enough for and that means a lot of things.

Fast action can only be faithfully captured by using short flash pulses.
Right and t.5=1/4500s at max power sounds good to me.

It seems that I was right after all. "Everything will stay the same". At least for 99.9999% of Pentax owners.

Most stuff with radiosignals (triggers etc) made for Canon, works with Pentax. My Hähnel triggers and pro-modules are for Canon, but works as gold on my K-3's and Mark II's..
The problem is, there is no sync signal on the middle pin with shutter speed over 1/180s (well, 1/200s with a trick)...

Hype it or wipe it.

I'm wiping off the utterly ridiculous hype and not listening anymore. This will surely be ridiculed elsewhere just like disco lights. Stop please.

Repeat...

Ok, let me put it in other words. If Godox will not come up with a trigger which can allow me to do HSS on my Pentax K3 II, why am I going to invest at least 4.000$ in 2 Priolite strobe? As we seen in the presentation movie we need at least 2 of these strobe to do an outdoor shooting.

Thanks, but I think this guy is joking with his strobe. Even if I have the money to buy 2 Priolite strobe, I wouldn't buy them. I would prefer to invest in a 70-200mm f2.8 lens, a FA31mm f1.8 lens and if I need to overpower the sun...a regular flash and a ND filter on my lens will do it.

Exactly right.
But for that 0.0001% ... it's a GAME CHANGER !!!

Yeah, right ...

If sync-speed is good enough for stopping action why use very expensive HSS equipment?

If there is a need to reduce ambient light without stopping down then one can simply use neutral density filters.

The advertising clearly tries to sell the high shutter speeds as being able to "freeze motion", which is misleading.

First, T.5 times are only quoted by companies that want to impress people. The much more relevant T.1 time will be much longer.

Second, in HSS mode the flash burst will last at least 1/180s, otherwise it wouldn't illuminate all of the frame. In other words, regular T.5/T.1 times only apply to standard flash pulses, not HSS.

I have to say calling a new flash system a 'game changer' and revolutionary is a ridiculous level of hype for a high speed flash system with similar features to dozens of others on the market.
It is the "game changer" for MF shooters and quite a change for some Pentax users.

Exciting news for studio shooters
It's not for studio as much as for location shooters.

Any data to support that numbers? Many Pentax users actually use studio flashes. Don't you use them? Well, whatever...

Jaad75, it is a 2.000$ strobe for God sake. This could be a game changer for those who use 645Z, but for the rest of us...

So for a 1/4 to 1/2 the price of a new lens, a photographer can pick up a lighting solution that makes their entire lens library act as a Leaf lens. Cost effective.

+1 combine that with the FF later this year ...... its a start ... its a great start.

I didn't say "sync-speed", but FP shutter. It is enough for stopping action in general, not some really fast movements and not some shutter distortion sensitive movements, but these are pretty rare comparing to most shooting scenarios. So yes, it freezes the action as well as the focal plane shutter freezes it which is quite ok.
QuoteOriginally posted by Class A Quote

Yes, about 3 times longer which is still good, and I believe it's an IGBT strobe.

Don't teach me how it works, please...

Yeah, just like let's say Profotos and cheaper than Briese or Bron...
It depends on a perspective.

I know, but "FP shutter" does not stop action any better compared to sync-speed, even if you increase the shutter speed.

If the respective motion distortion is not a problem, just shoot at sync-speed with a neutral density filter (if needed) and save a ton of money.

"It depends on a perspective" - that is true Jaad75

I'll wait for a decent trigger, which will do HSS with my flashes (Pentax AF 540 FGZ, or Godox AD180, AD360). It may be a long waiting, but less expensive when it will eventually come out.
