Godox Canon flash & Fujifilm TTL

My current setup is:

  1. Canon 7DMk2 with a 24-70 and a 70-200 with 1 Canon 580exII and 1 Godox TT685C (C for Canon) with 3 Yongnuo 622C as wireless TTL triggers.
  2. Fuji X-P2 with the ‘Fujicrons’, an 18-55, a 55-200 and the ‘pancake’ with the Godox TT350F and the XT1-F.

So the question is how can I use my Canon flash or the Godox-Canon flash on the Fuji? I need in the camera hot-shoe …

Fujifilm X-PRO2: Godox TT350F & the Fujifilm TTL

  • The aperture controls the amount of light from the flash/strobe
  • The shutter speed which is almost always slower than the flash (except for the Elinchrome strobes with their High-Sync) controls the ambient light.
  • The ISO that influence both the ambient light and the flashed light.

For a specific flash, the amount of light generated depend on the distance between the light and the subject (see the https://en.wikipedia.org/wiki/Inverse-square_law).

Fujifilm X-PRO2: HSS, TTL & Godox TT350F

X-PRO2/X-T2/X-T20: HSS & TTL. What a mouth full.

One of Fujifilm’s weakness against Canon and Nikon is the lack of a proper flash system. Roboshoot did a pretty good job at converting Nikon flash to Fuji so one could use Nikon flashes with Fujifilm:

  1. It’s expensive.
  2. I use Canon with Canon flashes, so I would have to buy new Nikon type flashes.

Fujifilm X-PRO2: Flash Not Working

Both Godox and Cactus are coming with Fujifilm compatible flashes. But let’s agree that up to now, flash has not been a strong suit of Fujifilm X cameras. That’s why I still use my Canon set because I need to do events and it’s almost impossible to make photos quickly without a reliable TTL functionality.

Many people have problem with the flashes not working. The same happens in both TTL modes and …

Canon Flash: EC vs FEC

What is EC? What is FEC? It’s alphabet soup that stands for Exposure Compensation and Flash Exposure Compensation. This is used to differentiate what photographers do on the camera vs what photographers do on the flash. The Nikon world is completely different from the Canon world.

In the Nikon world, the formula is: EC + FEC = Total Exposure Compensation. An Exposure compensation of -2 on the camera and a Flash Exposure Compensation of +2 = -2 …

External Flash Meter

Last night after dinner, Anon from Ymous fame, knocked on my door to ask for help. He’s the “senior photographer” at his photo club, so he can’t ask for help there. His wife bought him an external flash meter for his birthday. I haven’t used one of these, a Gossen, from the late 70s, that’s the late 1970s.

Anon tried the Sekonic flash meter with his Nikon D700 and his SB800 …

Canon 580EX II Flash Failures

Canon Rumors, you follow them right? has published a blog post: 580EX II Faulty by Design. Pocket Wizard is having many problems with the Canon 7D and the 580EXII. So they commissioned an “independent” study that found faults with the 580EXII flash design, especially when using the High Speed Synchronization.

Their conclusions are:

It appears that some combination of elements comes together to create the risk and increased probability of an IGBT failure within the …

Canon 7D: C.Fn I - 7 — Flash Sync Speed in Av Mode

There are 2 kinds of photographers:

  1. The aperture priority photographers
  2. The shutter priority photographers

The manual photographers do not count, they are so rare that they are lobbying for being listed under the Endangered Species Act.

Like the vast majority of the photographers, I’m an aperture priority photographer. To my shock and dismay, when I first hooked my flash to my Canon 7D, the flash worked but the shutter staid open “forever” seconds…

Some of the Secrets from the Flash World

I’ve been reading “Speedliter’s Handbook” from Syl Arena. Reading is nothing, the most important part is actually trying and experimenting. Here are my discoveries from some of these experiments.

Secret #1 of when using the flash

The shutter speed controls the ambient light when using the flash. The Canon 7D has a sync speed of up to 1/250th of a second with the flash. At short range, the flash is the main …

Canon: Number Of Flashes 580EXII Before Thermal Shutdown

Canon’s manual for the 580EXII flash says:

Cautions for firing continuous flashes

  • To avoid overheating and degrading the flash head, do not fire more than 20 continuous flashes. After 20 continuous flashes, allow a rest time of at least 10 min.

  • If you fire more than 20 continuous flashes and then fire more flashes in short intervals, the inner overheating prevention function may be activated to make the recycling time about 8 to 20 …

Canon: Flash Exposure Compensation

Sometimes, I wish Canon had a flash system as simple as Nikon’s. I’m not saying that it’s bad, under-powered, I’m saying is not as sophisticated or as flexible as Nikon’s. When dealing with flash, you must deal with exposure compensation. Exposure compensation is topic that you have to feel, there are no hard rules.

  • The exposure compensation does NOT work in manual mode.
  • The flash exposure compensation does NOT work …
