Thanks everyone for your kind words.
Viggo: Godox is coming out with a new version of the flash holder.

http://www.godox.com/EN/Products_S_type_Speedlite_Bracket.html

It might be better.  I have not used it myself though.

Soo, wait what, it just hangs there tightened with a screw on top? Lol, but I guess it works since they make it that way. I have a simple bracket myself I might use.

Viggo:  Phottix makes several softboxes that you can place your lights inside.  They are ok.  I've not had any issue with them yet.  The only thing I don't like about those boxes is that you are limited in tilting movement.

Thanks! My Swedish friend also uses them, but can't get them in Norway, and I wonder, are the rods inside the umbrella boxes any better than the "eBay stuff" ?

I'm aware of the limited tilt action, and it's a large drawback, but it's either that or not taking it with me due to needing heavy sand bags. I just take the chance with the inside mount boxes, lol.

Any one have a link to where I can buy this bracket?

Well done yokaew. I really like your work.

+1, I think you are very very talented. I don't not know just how to put it, but you use light extremely right! It looks great  :)

Thanks for sharing Knut! Awesome stuff. Really nice black and white converting on the last one there.

I was JUST looking at the SMDV boxes and they look great, I was hoping that someone somewhere would make a box that quality, and like the Elinchrom boxes that can take ANY abuse, but for mounting the flash inside, not on the outside. Where I live it's just a matter of hours between the flash tipping over, and I would rather have the box bounce and that's it, than landing directly on the flash. Or if it's a drizzle outside..

I really like the Godox 360.  It is very easy to use.  With 360W/S and the ability to do HSS, make it a great choice for outdoor shoots.

That's all the reasons I sold my Quadra and bought the 360. Great to hear you like it. Any recommendations for 70-90 cm Octa where I can place the flash inside and not outside pointing in? I have bought countless eBay cheapo's, but they brake for nothing. In fact, my most recent 80cm stood on a light stand in my living room and I suddenly heard a pop! And sure enough it broke one of the rods, from standing still inside! Wow..

Lighting / Re: Godox Witstro 360 flash with HHS
« on: July 24, 2014, 12:26:23 PM »
I bought the 360 today, and I have no triggers anymore, so I bought the kit that let's me control power output remotely and another Cells xc1 something or other to do HSS. The non-HSS is not supported by the 5d3, but a friend uses the HSS vertion for the 5d3 and I was told it works for the 1dx also.

Backorder two weeks so I'll have a loooong wait before I can try it out.

Yokaew: Awesome shots, and a superb way to show off what skills and modest gear can do, absolutely spot on all four if your shots.

What's is your take on the Godox 360ws?

I just bought the Witstro (Godox) 360w flash, if anyone has any experience, please share. I won't be getting it for a couple of weeks, but will share my experiences and thoughts about it here when I have tested it.

Here's a shot from earlier today, I have rediscovered hard light, and I love it!

Two Canon 600 RT bare bulb to the back left at 1/1 power, zoomed to 50mm. Triggered by the Canon ST-E3. Sigma 50 Art at f1.4, iso 100, 1/8000s.


Nailed it at 1.4! Great shot!

Thanks Jamsey! It was the only shot I took also. 50 Art is such a killer lens.

This thread is such a good idea! I've recently decided to take the plunge and purchased a flash/trigger and everyone's pictures and explanations are so helpful. Hopefully I'll get the hang of off camera flash and will be able to contribute to this thread.

That's great to hear! We're looking forward to your shots and inputs. Welcome to CR also :)

I dont know but A PCB Einstein @ 640 W/s would take atleast 6+ Speelites to get kinda close to the full power output. It would be the same with these if they are measures the same.
Thanks for the tip, but I can't buy Einstein, it's not sold here and I can't import due to importing rules, think it's about the lithium battery, and I think thy used to be only 120V , not 240V.


Not suggesting that you do buy an Einstein, though I recently got two and they are very good. But for the sake of accuracy, the Einstein doesn't have a battery in it and is allowed to be shipped anywhere worldwide with no restrictions (not saying there are not import regulations unrelated to batteries), also they run on any voltage from 95-250VAC 50-60Hz automatically, effectively you can plug them in anywhere in the world and they just work.

But international shipping is a pain and for service or warranty they have to go back to Tennessee and the Einstein also doesn't do HSS.


As for the power output, as IMG_0001 said, the small flash GN only covers a very small area, the Godox has a much wider spread so actually puts out much more light. It is very difficult to compare flash power on specs, even when you use the same figure to do it. For instance if you compare a 1200WS Profoto to an older 2400WS Profoto in the same modifier the 1200 actually gives you one stop deeper dof because it is so much more efficient, WS refers to potential energy.

There is no accurate way of comparing flash output, there is no standard, without firing them next to each other in the same modifier. But the Godox will give you much more light output than the 600-EX-RT.

Addendum: The Godox is rated at GN 52 with a circular beam spread of 65º, the 600-EX-RT is rated at GN60 with a rectangular beam pattern of a 200mm lens, or 12º. This means the area the Godox covers is around eight times bigger. In practice I'd expect the Godox to put out a couple of stops more power than both your 600's together.

Bearing in mind that 65 degrees is around 35 mm focal length and that Canon's 600EX-RT manual states GN36m at 35mm and ISO 100 and 1/1 power. Then, given Godox GN is 52m:

52/36=1.44 times the distance for the correct exposure and given the the inverse square law,:

1.44^2 = 2.

The Godox flash is then pretty much 2 stops more powerful than the Canon. So Private was pretty right.

And I think it is also good to remember that 1 more stop than a 600RT requires two 600EX-RT,
+2 stops = 4 flashes;
+3 stop = 8 flashes and so on.

Therefore a pair of those Godox flashes would be +3 stops and be roughly equivalent to 8 Canon 600EX-RT.

And then comes battery life, overheating possibilities, recycle times and so on...

Thanks again. It starting to look like getting the Godox for sure. I know that for each stop I need twice as many  speedlites, that's why I have two, and only two. After that it starts to become expensive and loooots of batteries.


If you do so, keep us informed of how you like them.  I was interested in some of the Godox products for a small home studio, but I am yet to decide if I trust the brand enough to hand them my precious beans.  Still, some of their products like the bare bulb speedlight and the lithium battried speedlight appear to be relatively well perceived and the prices are very attractive.

I already have a PB820 batterypack for my speedlites and they have seen some abuse, but work as new, and it turns out I can use that pack on the 360 as well, neat stuff.

Only thing is, I saw a transmitter and receiver that allowed me to adjust power remotley, however it did not support HSS. Looks like I have to have one remote in my pocket to adjust power and another to transmitt from camera to both control power and have HSS, it seems like a pita, but hey, they're cheap.

Viggo, I also have a pair of Einsteins and they are excellent, but I understand the import issues & costs.  I wanted to ask you about your need for HSS.  A few weeks ago I spent a good deal of time reading Paul Buff's thoughts on the use of HSS and why he will never implement the feature into his Einstein or other lights.  Essentially he feels that the power reduction and sync issues aren't worth it and you're better off adding more power to get to your camera's x-sync speed instead.  I can see both sides of the issue, but he had a lot of compelling arguments.  I can point you to some of the posts on his forum if you're interested.

I think one of the key points for HSS is the ability to select very narrow dof without resorting to variable PL filters which hurts focus etc. And that is Viggo's style, fast primes wide open.

I think Paul is being a little economical, PCB are happy to boast, very loudly, about the flash duration speed which is as dependent on low power settings as HSS is inefficient. There is no doubt there is a demand and interest in HSS for studio lights, and IGBT is the way to do it.

Indeed, I don't want to mess around with pitch black filters, much more fun to simply set the exposure I want for background and the dof (VERY rarely narrower than 1.4) and just shoot. I found that the power lost in HSS is so worth it to able to use HSS. But that will make the speedlites lack power in daylight, and is why I want something like the Quadra, but with HSS.

Hmm, I had completely forgotten about the B1....

Thanks for he detailed info, great stuff. And I should've known, because it's just to compare my deep octa 70 cm to a cheap 70 cm octa off of eBay I have, the deep octa is MUCH better to reflect the light out of the octa.

Such a shame the Acute 600 doesn't do HSS, lol..

The speedlite is GN60m zoomed at 200mm while the Godox flash head is GN52m for a wide angle reflector (haven't seen how wide and that is not standardizied as far as I know) . In a similarly wide angle, the 600 probably gives under GN20m as the light intensity reduce in proportion of the illuminated surface, or to the square of the edge lenght of the illuminated area.  (Inverse square law).

Thanks, that makes more sense, but still, I was thinking I would not use a reflector at all inside a soft box. It's almost impossible to figure out the output without trying both speedlites and another lamp inn the same box and measure the f-stop with a light meter at a given distance it seems. I don't want to buy a flash that's barely more powerful and the two 600 RT's I already own  :D
