Control Flash Power Wirelessly with PocketWizard Tech Inside New Sekonic L-478 Series Light Meters

PocketWizard is proud to announce its wireless power control technology can be found inside Sekonic’s new L-478DR touchscreen light meter.

Announced today by Sekonic, the LITEMASTER PRO L-478DR and L-478D are the world’s first and only dedicated color touchscreen light meters.

Ideal for all types of storytellers, the L-478 series offers light measurement and control for photographers and filmmakers alike, plus additional wireless flash triggering and power control in the L-478DR model.

Whether it’s filmmaking or photography, great storytellers use light as a main character and as a method to define the mood, focus and setting. Having a tool that allows you total control over dynamic range and multiple light sources make you confident about the craft while focusing on the art.

Just a few of the groundbreaking features of this new series include:

  • The world’s first touchscreen light meter
  • The world’s first touchscreen cine meter
  • Wireless triggering (L-478DR only)
  • Wireless flash power control (L-478DR only)
  • Enhanced HD cine and cine features

  1. I already have some PWs, I was thinking of adding a AC3 to the mix. So if I get this right, this not only will it fire my lights but it will eliminate the need for an AC3? It’s a Skonic meter + AC3 on steroids?

      I love your description of the L-478DR being an AC3 on Steroids. Yes, the L-478DR emulates the control of the AC-3 in “M” (manual) mode. Moving the sliders on the meter is just like turning the dials on the AC3. If you are using the meter, the AC-3 should not be on the camera. Also, the triggering Mini or Flex on the camera needs to be set for “No Change (Trigger Only)” in the PW Utility software. The Meter then zooms away by providing the exact brightness of each flash indicated as an f-number so you can get the exact lighting ratio you want and you can repeat it. If ambient light is in the mix, you can also know the percentage of flash in the total exposure and make exposure adjustments to tune that as well. The L-478DR saves time and puts you in command of the lighting.

  2. My Sekonic L-478DR works great with my 3 PocketWizard FlexTT5’s. I configure all three FlexTT5’s the same way with C1 configured standard iTTL and C2 configured for the same Channel as C1, but I set it as transmitter only and No Change (Trigger Only). This way, I don’t have to remember which unit is configured for my camera and I can switch between iTTL camera control or Sekonic Meter control very easy. All I do is keep my remote FlexTT5’s set to C1 and set my camera’s FFT5 to C2 when I want the Sekonic Meter to set the levels, otherwise I set all three to C1 for the camera to control output flash.

    Works like a champ!

    So, although the FlexTT5’s and MiniTT1’s are iTTL Nikon and eTTL Canon compatible (camera brand specific), the L-478DR is not? I will be able to control 3 zones with the meter with flashes set on manual, but NOT be able to use the iTTL/eTTL system and do exposure compensation by group with the L-478DR? I have been researching this for days and have not been able to find a conclusive answer. It appears that to use the TTL system, an AC3Zone Controller will still be necessary to make compensation adjustments after metering with the L-478DR. Thanks in advance for the help.

      This goes to the basic way the PocketWizard ControlTL radios, MiniTT1 and FlexTT5, and now the Sekonic L-478DR are able to control the flashes. That is, in order for the flashes to be cable of adjusting light output from a signal, either from the camera normally with a Nikon or Canon system, or from a radio signal, the flashes must be set to eTTL or iTTL. If you set the flash to manual and a power level setting, all the flash can do is fire at the power level setting you made. That is the design of the Nikon and Canon flash system. If you are using the Mini and Flex with AC3 set for “A” than you are “influencing” the camera’s automatic flash exposure system. That is “+/-“ flash exposure correction. The camera decides the strength of the flash, or length of flash duration, from a pre-flash reading, aperture, shutter speed, ISO and ambient brightness input and you can add or take away from this by turning the dial on the AC3. The L-478DR works like the AC3 set to “M”. For both, setting the dial on the AC3 or the slider on the power screen of the L-478DR determines the strength of the flash (0r length of duration). When you make a MANUAL adjustment on either the AC3 or the L-478DR, that information is immediately sent to the FlexTT5 which holds the flash-level command and awaits the “trigger” signal from the camera-mounted Mini or Flex (that is why you need to set the camera-mounted PW to “No Change-Trigger Only”). When you press the shutter release to take the picture, the trigger signal is sent from the camera mounted PW. The Flex under the flash then tells the flash what power level to fire and the flash fires at that amount. The picture is made. The flash exposure amount is what you set. If you want to make a correction and are using the meter, go back to the power screen and move the slider. I suggest checking it with a meter reading to make sure it is at the aperture number you want. If you have not seen the Webinar we did with Mark Wallace on this, I recommend it.
