I am reading Bryan Peterson’s book, Understanding Flash Photography... Just my humble opinion, but not the source I'd go to. Peterson is more of a landscape/nature photographer and his knowledge of flash is pretty antiquated (hence your reliance on guide numbers and distance scales). I'd recommend starting with something like Neil van Niekerk's website or ...

The sync voltage limit on a Cactus V5 is 300V. As long as your flash doesn't go over that, you should be fine. In addition, any dRebels that are newer than the 300D have a sync volt limit of 250V on the hotshoe, according to Chuck Westfall, the technical rep for Canon, answering a question in a 2007 tech tips article for the digitaljournalist.org: I ...

Sorry, there is no way to make older studio strobes automatic, or even semi-automatic. You must use Manual mode for every photo. 1/200 is the max sync speed on your camera, but when using radio triggers, there is sometimes a very slight delay introduced. To be safe start with with 1/160 f/8 ISO 100. You can then adjust the power of the strobes to get the ...

IR Systems Think of it this way. Digital cameras are generally made by companies that do other consumer electronics. So, the first wireless controls for off-camera flash that were built were based on existing IR* remote technology—like how your TV remotes work. This has an obvious advantage for manufacturers of not requiring radio bandwidth allocation in all ...

Yes, there is the possibility that vintage strobes with high trigger voltages can damage wireless receivers/transceivers attached to them. The danger would only apply to the receiver/transceiver physically connected to the flash via either hot shoe connection or PC cord. There is no danger to the transmitter and camera connected to the receiver via wireless ...

The Yongnuo YN568EX II flashes have built in optical receivers that operate on Canons optical wireless system that uses very short pulses of light to communicate. You need an optical Master flash (such as another YN-568EX II) or Canon compatible wireless optical controller (such as the YN-ST-E2) on the camera to control them wirelessly without attaching ...

I've been using the YN622C-TX and YN622C transceivers for about the last four years. I think I have gone through maybe three or four sets of alkaline batteries in the TX. The transmitters and receivers don't use much energy at all. The transmitters are very low powered radios that only transmit a few milliseconds per exposure. The receivers are even more ...

The only way to use a 750D to trigger an off-camera YN-560 IV without adding any other hardware is to use the pop-up flash to trigger the YN-560 IV in "dumb" slave mode. The YN-560 IV has a built in radio receiver compatible with the YN560/RF605/RF603 communication protocol. Your camera has no built-in radio transmitter (none of Canon's current cameras do), ...

Using the Godox TT350N as a means to control your other Godox speedlight is a perfectly viable option. If you later decide to buy a dedicated trigger, you can control both of them. The only drawback is that the controls on the flashes themselves are not as straight forward as they are on the Godox X2 or Xpro. Plus you will probably never use the speedlight ...

If you're trying to control a Yongnuo YN685 via radio using a Godox X2T transmitter, it won't work. They speak different "languages" that aren't compatible with one another. You can use a Godox X1R receiver attached to the hot foot of the YN685 flash to receive the signal from the Godox transmitter, or you can get a Yongnuo YN622 compatible ...

You're probably not doing anything wrong. It's that the JJC triggers can't tell what they're being used for, and both receivers are getting the transmitter signal at the same time, and tripping the shutter release and flash burst at the same time. The shutter release has to happen before the flash burst. If you stick with these triggers, you need another ...

As of 2018, aside from the built-in RC "smart" optical system made by Olympus and Panasonic, there are a few radio triggering systems that now support TTL and HSS with MFT (micro four-thirds), as well as remote power control. There are also manual-only systems with radio triggers built-in that support remote power control from the MFT hotshoe. Full TTL/HSS ...

The following radio-based flash triggering systems can communicate TTL for Pentax: The Cactus X-TTL system with their V6II/IIs triggers can give you remote power control over TTL Pentax flashes, HSS sympathy triggering, and full TTL passthrough to an on-camera flash mounted on top of the trigger, as well as P-TTL with remote flashes. Phottix's Odin II ...

Yongnuo only makes two types of flashes with built-in radio triggers: manual-only flashes (YN-560III & YN-560IV), and the Canon-RT compatible flash, the YN-600EX-RT. The YN-565EX/568EX/500EX (and MkIIs) models do not have a radio receiver built in. (The YN-685 apparently has a YN-622/RF-603/RF-605 receiver in it). The built-in slave modes on the YN-...

Actually, the most problematic part of your equation here is the 380EX. It doesn't do Canon's wireless eTTL slave mode, which is probably why you're looking for triggers, but it has no manual power control setting capability, so even if you can get it to fire off-camera, you can't control the output and it can only fire at full power. And if you get TTL-...

The goal of all of them is to fire a flash that's not on the camera. Let's take a look at what all this means radio trigger (e.g. PocketWizard) They talk to each other via radio, which means there's no flash firing just for communication purposes. You will definitely need a sender unit on the camera, because no camera (as of yet) has built in sender. This ...

Most low-cost (say < US$50/set) flash radio triggers do not support eTTL or HSS. They are "manual-only" triggers. It the triggers/flash only have a single contact/pin they're definitely manual-only, because that big contact/pin in the center of the hotshoe "square" is the sync signal and that's the only signal that can physically be communicated. There ...

Does my flash actually have a wireless reciever in it (Instruction manual seems to point to "yes")? Yes. It has both an optical transmitter and an optical receiver. That means that it can be used both as an on-camera Master or an off-camera Slave using the Canon E-TTL optical communication system. If I use the flash on my hot shoe, does it "transmit" to ...

Of course it's possible. You have at least 3 solutions: An infrared transmitter: the camera and flash must be in sight, no obstacle between the two. Operation is bad in daylight. A radio transmitter. The most universal solution. the transmitter will might be used in other cases. In case of a long exposure, the solution proposed above is good: fire the flash ...

The only way you could trigger the Godox SK400 with your current setup would be to use it in "dumb" slave mode where the flash from the Yongnuo speedlight would trigger it. The radio in your Yongnuo trigger (regardless of which Yongnuo system you have - there are at least three separate Yongnuo radio protocols that are not compatible with each other: YN622,...

Provided that all you want a wireless solution to do is tell the flash when to fire, any transmitter/receiver set that are compatible with one another will be able to do that. The easiest way to insure this is to buy a set that includes both a transmitter and a receiver. This is based on the assumption that the flash, camera, and triggering system in ...

What you're missing is that Yongnuo has three different flash triggering systems: YN-560-TX and RF-60x manual-only triggering system. The YN-622/YN-622-TX TTL/HSS triggering system. The Yongnuo clones of the Canon "RT" triggering system. All three groups use different radio signalling communication protocols. Your flash and its built-in trigger is from ...

I wanted to know if I can use Godox AD 200 without the transmitter such as X1 T or Pro? Yes, there are several methods one may use to trigger a Godox AD200 without using a Godox 2.4Ghz transmitter. You could use a wired connection between your camera's PC terminal (or an adapter mounted on the hot shoe if your camera does not have a PC terminal) and the ...

I have currently a Nikon D850 along with a SB-700 flash, whose main purpose is to shoot cosplays in events. I'm happy that using it on the hotshoe would get better photos than without it, but still I'm not satisfied. So I'd like to experiment to having it off-camera. Now, I've read [various] ways to trigger the flash off-camera, and I still am ...

There are a few new systems appearing on the horizon that look like they will allow power control from any iso-compatible hotshoe, including those of mirrorless cameras like mft and Fuji X. But they're typically flash-and-trigger combination specific and are likely to be manual-flash-only on mirrorless. AFAIK, there are no full-function-TTL-capable radio ...

Good news and... Not quite bad news. First, this is a modern flash with a low trigger voltage, and there is no risk using it on any modern camera. So, good news. Second: this will work with any generic radio trigger, from cheap to expensive. However, its headline feature is built-in radio triggering, and that works with Yongnou's own triggers, which they ...

Probably because most users of the 1-series cameras from Canon don't expect to use their 1-series camera in situations that lend themselves to infrared remotes. Most pros who desire to release the shutter of their camera via a wireless remote use radio triggers that are much more reliable and configurable in environments that are usually rich with sources ...

There are several methods you can use to fire the 430EX remotely, and while most require additional equipment, not all of them do. Canon wireless e-TTL (IR) Canon has two built-in wireless systems for remotely firing flashes with its cameras: a radio system and an infrared system. None of your units speak the radio system, but the 430EX can be used as a ...

While the Yongnuo RF-603 (and -603II, and -605) and YN-560-TX units all come in Canon and Nikon flavors, the difference is solely for the "wake-up" feature (i.e., half-pressing your shutter button will wake up the remote flash if it's sleeping to conserve power). The Nikon and Canon TTL pin layouts are different, so the trigger "foot" used for the on-camera ...
