General Discussion / Fast duration speedlight & trigger system for leaf shutter cameras?
« Last post by Taro on January 12, 2017, 11:30:57 PM »
I've been using Yongnuo's YN560-TX (in 603 mode) and YN560 (III, IV) with Panasonic LX100 camera for some time now. With the leaf shutter camera, I can sync at 1/2 power at 1/1000 sec comfortably. Even at 1/2000 sec, I get some flash in my exposure.

I tried replacing this setup with Godox X1-N and TT600's last year. To my disappointment, the X1 remote system was slower than Yongnuo in firing, such that my flash exposure at 1/1000 sec was roughly 1/2 stop weaker in comparison to the result I can achieve with the Yongnuo's. Beyond 1/1600 sec, I got virtually no flash in my exposure with the Godox X1 system.

To tame strong day-light with flash and minimize recycle time at the same time, I use two speedlights in a reflective, silver umbrella, and set the speedlights' output to 1/4 or 1/2 power. I try to use the 'meatiest' part of the flash output curve by closing the shutter when the flash output weakens. In my subjective experiment, it's most effective to use shutter speed between 1/1000 - 1/1500 sec to achieve this effect.

Are there others on this forum who attempt the same? Are there systems sync faster than the Yongnuo? How about Godox XT32? Is it any faster than X1?

My guess would be "probably not" for a couple of reasons:

1) The microcontrollers (electronic brains) used in these types of products give the manufacturers the ability to defeat these types of "load different firmware" mods. Implementing them is borderline trivial. In these cases, firmware becomes encrypted object code that can only by loaded by a product that has been pre-loaded at the factory with the appropriate "key". I'm not sure if Godox implements this scheme but I've seen other photographic accessory manufacturers do it.

2) Before his passing, I had a brief conversation with Paul C Buff about the possibility of adding TTL support to Buff Einsteins through firmware. He indicated that significant changes to the Einstein hardware would be required. That's not to say that Godox didn't design their hardware to be both TTL & non-TTL from the get-go. I'd wager that if they Godox did design the circuitry to be "dual purpose", they did it in such a way that they could save money when manufacturing the non-TTL version by leaving the TTL parts of the circuit de-populated at manufacture. Thatís a pretty common practice.

Just my thoughts...

Hello guys,

I just wondering if someone tried to enable the TTL function by flashing the TTL firmware to the AD600BM strobe? I'm just think they maybe just enabled this feature with software and I'm think the electronics are the same. Don't get me wrong, I'm just interested in software and electronics so this comes into my mind.

Cheers!

Let me know if you find them again.

Thanks

A plug for Elv's favorite vendor, Adorama.

As of this morning, they are having a pre-Black Friday sale on the Flashpoint R2-branded Ving flashes (V860IIc, V860IIn, & V860IIs): $109.95 + Shipping.

Wow, that's really strange.

I've got a couple of different spreads of the 5-inch grids (bought each individually) but I can't even find them on the Godox site anymore.... :-(

I would try sending an e-mail to Godox support but most likely what you're trying to do isn't possible with what you've got.

Each camera system has a different "protocol" (the sequence of electrical pulses generated by the hotshoe to trigger the flash) for HSS mode. The job of the radio remotes is to "bridge" those electrical pulses from the hotshoe to the flash, even though they aren't physically electrically connected. In order to do that, the remotes must "know" something about the electrical pulses for each camera system. So while your transmitter understands/transmits the Sony/Minolta "protocol", your flash expects to receive the Nikon "protocol" (and gets 'confused' when it sees something different).

The Test button works because that just sends a single pulse for each press of the button, which is non-HSS and common across all flash brands. Does your setup work in non-HSS mode?

FWIW, Adorama is having a "pre-Black Friday" sale on the Flashpoint re-brands of the Godox Vings. You can get a V860iis for $109.95 + shipping and solve your problem quite easily: http://www.adorama.com/fplfsmzl2so.html

I just got the Nikon version of this, and I can't find a thing to complain about! It includes a Li-ion battery which they claim will last for over 600 full power shots between charges. It recycles very fast.
I have been surprised to find that in TTL mode there is no perceptible pre-flash. It seems to get the exposure right very well.  I have been used to sb910 and Mitros+ where the pre-flash is obvious.

I wonder if it is using some other method, perhaps measuring the reflected light during the actual exposure, or is it using pre-flashes that are so dim and brief that we cannot see them.

The first time I tried to post this I got a message "Cannot Post to This Group." in the subject line.  Perhaps that is why the group does not seem very active.  I hit "Enter" and it posted it anyway.
