What is TTL?
I’ll start part 2 (part 1 is HERE) by describing what TTL actually is. Feel free to skip this part if you already know this.

Back in the good old film days a lot of flash guns had a small calculator in the form of a chart or a small disk that rotated. These things basically calculated what setting worked for the Guide Number of the flash you were using. I had a Vivitar 283 back in the early 80′s, which was one of the most popular and reliable guns of it’s time. It had a dial built into the hinge of the bounce head (photo left). You set the dial to whatever ASA/Din number your film was (now called ISO) and the dial told you what distance you would cover with the varies apertures. The coloured sections corresponded to a dial on the front of the camera. It all goes a bit hazy after that…it was a long time ago. But I do remember having a cable that plugged into the front of the gun to use it off the camera.

Fast forward to today and we have much more sophisticated flashes that talk to the camera and vice versa. The camera takes it’s exposure reading through the lens (TTL) and tells the flash the information it needs to know. The flash then works out how much power it needs to put out to achieve a good exposure. The flash gun can also let you know via it’s display if the right exposure was obtained.

What TTL Cable Works With The X Series
If you want to do off camera TTL photography with your X Series camera, you will need an EF-42, EF-20 or an EF-X20 and a TTL suitable for a Canon (usually called ETTL in Canon speak). The Canon hotshoe pins match the Fuji ones and allow TTL flash with a Fuji X camera. Nikon has a different pin arrangement and definitely won’t work in TTL. Remember to turn off both camera and flash when attaching a TTL cord as the contacts are sliding into position and could short out. I’ve never been a Canon shooter so I don’t have access to their flash guns and I can’t say if an X camera and Canon flash can speak to each other and work in TTL harmony. Nikon guns do not work in TTL. Nikon flashguns will work on an X series camera in Manual or Automatic, but not in TTL. If used on an X camera’s hotshoe or with a TTL cord, A Nikon flash is only being told by the camera to fire – exposure settings are up to you the photographer. The flash must be set to Manual (not TTL) or it won’t fire.

Canon’s own ETTL cords will be great for the job, but they do tend to be a bit spendy. I bought the Pixel FC-311/S 1.8m cable (for Canon) from Amazon UK for £17 and it works fine. A really nice feature with this cable is that it has both a tripod mount and a cold shoe for attaching it to a light stand. This could come in really handy (although a longer cable might be better for using on a light stand). I’m using an SB700 soft case to hold the Fuji EF-42 and the TTL cable and there’s even space for a plastic foot too.

Hand Holding For Off Camera Flash
Obviously if you are doing off camera flash without the use of a stand or tripod, you have to be careful of camera shake as you’ll be holding the camera with one hand. Thankfully X cameras are great for hand holding due to their size, weight and the lack of a mirror popping up and down. But having a good solid grip and steadying technique is very important. In the photo below you will see the grip I use. By holding the flash in the left hand and crossing it over to the right, you can rest the camera on the left shoulder, the flash can be stretched out as far to the right as you like, as long as it’s pointing in the right direction a bit of shake won’t make any difference. If your TTL cord has a hotshoe or tripod mount at the flash end (Like the Pixel cord), you could easily use a handle. Lastolite do an extending Handle and a Brolly Bracket.

So that’s off camera TTL, what you do with it after that is up to you. There are some interesting accessories available like the Rogue Flashbenders to spread or direct the light, or Rogue Grid to focus it exactly where you want without light spilling all over the place, which is a must if you have a coloured gel on the background. The possibilities are vast and a lot of fun.

This is part one of a three part series on using flash the Fuji X Series. This part is a review of the EF-42 flash and this will be followed by “Part 2 : TTL Off Camera TTL” and then ending with “Part 3 : Using Multiple Flashes With Radio Triggers”.

I often get emails asking about using Flash with the Fuji X Series. Mostly the questions are about using TTL, Nikon or Canon Flashguns or the Nikon SU800 Commander with the X series. Another big question is – Can an off camera TTL cord be used and if so, which one? So I thought I’d take a fresh look at using Fuji X cameras with flash. My friend John a commercial photographer and he’s really tempted by the X-Pro1, but he uses flash most of the time and isn’t sure if the X system is up for it. I have a job at the end of this week that might need flash due to the time of day in January and a dark venue. There won’t be time to use one of my Nikon guns in manual mode with a radio trigger, so TTL will be a must. This all added up to a good excuse to pick up a Fuji EF-42 TTL Flash and give it a blast.

FUJIFILM EF-42 TTL FLASH
The EF-42 is basically a Sunpak PZ42X with a jacket on (the EF-20 is also a Sunpak model). It’s not as well made as a Nikon or Canon flash gun, but at half the price, it’s good enough. When you mount the flash on the camera and switch it on, autofocus won’t work until the flash charges and the Test/Charge light is illuminated and like a kettle boiling, it seems to take a long time when you’re watching it. But when it’s lit there’s no problem and everything works as it should after that. But I would rather take a shot without the flash firing than miss the shot as it could maybe be recovered in Lightroom with a bit of exposure and a possible conversion to black and white.

The back panel on the EF-42 is minimalist compared to a Nikon or Canon unit, with buttons for Mode, Select, On/Off and Test. It’s certainly easy to understand how the controls work, which is a breath of fresh air if you have ever used an SB800 at any point. But it would be nice to have dedicated a couple of buttons for -EV & +EV, as there’s too many button presses to move up and then down EV. TTL works well and the handy pop-out wide angle lens is useful. I think it’s a bit mean not to include a dome diffuser or a foot/stand, but I picked up a diffuser from eBay and I had a spare Nikon foot. A Nikon SB600 Dome Diffuser will fit, but it’s very tight and once attached it would be a good idea to leave it in place. A soft case would also have been a welcome addition, but I have a solution for that in Part 2. The hotshoe mount at the bottom of the flash is plastic and looks cheap, plus a switch style lock would have been preferred over a screw down plate.

I would recommend buying a Dome diffuser as the bare flash can be a bit harsh. With the diffuser attached and the flash head tilted up you will get great soft and even light that can fill a small room without any problem. You can find a suitable diffuser on Ebay for very little money. There are even packs of three available (one white and two coloured) that allow balancing the colour of the light from the flash with the room (I prefer gels).

In conclusion, the EF-42 does the job well, but could be a bit better on the built quality front. I think if Fujifilm had made this flash from the ground up, it would have been a much higher quality unit. Now that the X Series lenses are plentiful (almost), it would be nice if Fuji could dedicate a little time to develop a flash system on a par with Nikon’s CLS system, but with built in radio instead of infrared and a dedicated commander unit that allows the user to set the power on multiple flashes without moving from camera position. A dedicated flash system is about the only thing the X Series is lacking now.

So that’s the EF-42. Stick it on the camera, set it to TTL and you’ll get a pretty decent job. But a flash on a camera hot shoe is not the best look for your pictures. The shots look flat, lifeless and can make ugly shadows in the background. So in Part 2 we will look at getting the flash off the camera using a TTL cord and what cord will work with the Fuji X range.

The EF-42 is available on Amazon UK for £155
