Ideal for digital still photographers working with remote flash set ups, the new L-478DR model incorporates PocketWizard® wireless radio technology for in-meter power control of select studio flashes connected to PocketWizard ControlTL® receivers as well as standard triggering with the entire PocketWizard wireless family of products. Both the L-478DR and L-478D are fully firmware upgradeable and use Sekonic’s breakthrough Data Transfer Software (DTS) system that automates meter calibration to the camera in use. In addition, an array of unique cine features put these meters in a class of their own.

“Whether telling the story with stills or in motion, Sekonic offers the perfect meter for a photographer or filmmaker’s imaging needs,” said Phil Bradon, Sekonic’s USA Product Marketing Manager. “The new compact LITEMASTER PRO models provide a familiar interface for users and display ambient, flash, cine and other information in a clear and understandable way.”

Flash Power Control with L-478DR

PocketWizardradio technology enables reliable, fingertip control of remote flashes connected to PocketWizard ST4, MC2 and FlexTT5 ControlTL receivers and Nikon and Canon Speedlights connected to a PocketWizardFlexTT5 transceiver. Offered in both FCC (USA) and CE (Europe) frequencies, the LITEMASTER PRO L-478DR will support all ControlTLChannels and Zones (A, B, C). Power levels are easily controlled by touching or moving a finger over the L-478DR screen. Touching ControlTL Zone buttons marked A, B, or C allows the user to switch remote flashes on and off at the meter to make separate exposure measurements for easy adjustment of desired lighting ratios. Standard Channel and Quad Zone capability allow triggering all standard PocketWizardradios and flash units incorporating PocketWizardradio receivers. To learn more about PocketWizard, please visit

Exposure Profiling

Sekonic’s pioneering DTS (Data Transfer Software) Version 3.0, introduced earlier this year, enables quick dynamic range mapping of both digital still and motion cameras for the most precise control of light and exposure. The automated process requires using the L-478’s 5-degree viewfinder and recording images of one of Sekonic’s Exposure Profile Targets  or one of X-Rite’s ColorChecker® series targets, all available as a separate purchase. Measured data from industry-standard targets can also be manually entered in the software or meter. Up to ten camera profiles can be stored in the meter. Any number of profiles can be stored with the software. Once loaded, the Sekonic L-478DR/D series can make incident and reflected light readings that are precisely tuned to the dynamic range of the profiled camera. A wide range of in-meter adjustment as well as complete exposure data input is also possible using the graphic interface of the L-478 meters.

Unique HD Cine / Cine/ Light Measuring Features

Today’s Digital Video cameras offer boundless versatility. The L-478D meter has two motion-capture modes to fit the shooting needs of every cinematographer. Touching the screen easily sets shutter speeds for HD SLR cameras or for Cine shooting, a touch of the screen controls frame rates and shutter angles. This new meter also allows users to create unique frame rates and shutter angles for special effects.

Sekonic designers also added a unique filter compensation mode that enables getting exact light levels with the filtered light sources used in motion picture production. By simply touching the new L-478D screen a user can instantly call up light source or camera filtration expressed in industry standard CTO/CTB/ND terms. Users can also create filter factors with names for quick call-up and use. Up to four filters can be used together in a pack. After the compensation is selected, they simply measure the light and drop the filters in place for precise control illumination and exposure. Extended ISO to 409,600 and brightness measurement in Lux/FC and Cd/m2/FL*2ensures that the L-478 is destined to become a major player on movie sets around the world.

Power and Accessories

The L-478-series meters are powered by two convenient AAA-size batteries. Both meters come standard with two AAA batteries, case, strap, user-applied anti-glare film CD with DTS software and instruction manual, and Quick Guide. A five-degree viewfinder is available as a separate purchase for reflected light readings and calibration and measurement using camera profiles made with the Sekonic DTS system.
