Equipped with a large and intuitive 2.7" color touchscreen LCD and now featuring built-in radio triggering for the 2.4 GHz Phottix Strato II wireless system, the Sekonic LiteMaster Pro L-478DR-U-PX Light Meter Phottix Strato IIfrom Sekonic LiteMaster Pro L-478DR-U-PX Light Meter Phottix Strato IIwill make incident metering for ambient and flash light super simple. The 4-channel system also has separate selection between 4 groups with measured values maintained for ratio determination.

Notable for the L-478 light meter series is the large color touchscreen, which allows for fast control over settings for both ambient and flash metering. The meter is quite capable as well, able to function within a range of -2 to 22.9 EV at ISO 100. And, for the current crop of hybrid shooters this model expands on its standard stills functions with two distinct video modes: Cine and HD Cine. These settings give access to frame rate selection from 1-1,000 fps as well as shutter angle settings from 1-358° as well as ISO 850 for Canon cinema cameras.

Guaranteeing the best possible performance is a suite of functions and features that will ensure users have the best tools available to them. Among these is a flash analyzing function that uses ambient and flash simultaneously to allow for shooters to dial in their preferred mix. Also, using the included Data Transfer Software users will be able to do Exposure Profiling for their camera by using the optional 5° viewfinder, showing dynamic range limits and knowing that you will have an accurate exposure. Alongside this is a Filtration Compensation Mode that allows for the meter to account for filter factor, which can now be done at up to 12 EV for landscape shooters using high-density ND filters. Other features include a contrast function for comparing brightness, a memory mode for 9 readings, and illuminance or luminance measurement.

Q: 5. Can a Godox AD600 attached with a pocket wizard 3 be triggered and still use my Godox trigger while activated ?

A: Yes, you can trigger the AD600 with the wizard.

Q: 6. How well will this work with the Indra 500

A: It does a fine job. You must set the Indra to receive Strato II signals. It would be best to use a Strato II Transmitter as it has ABCD groups. But you could also use an Odin Transmitter which has ABC groups. There is no power control as the Phottix system is not set up to allow it.

Q: 7. Can I use it wth other Flash units in the same as the non Eilenchrom version? In case I want to add Eilenchrom lighting later.

A: I'm sorry, but I don't know. I don't have the Elinchrome verson.

Q: 8. Hi,do you believe it would be usefull to buy the Elinchrom HS skyport as a complement to the Sekonic 478dr ? As all I see is the High speed sync feature that the skyport would provide. Other than that I believe they have more or less the same functionality. Thanks

A: Yes, you should decide whether you need hi speed sync or not. For that it's wonderful. You really don't need the HS if not. However if you use the regular Skyport now the HS is so much nicer.

Q: 9. Does this device measure for shutter speeds between 1/125 & 1/250 (such as 1/160)?

A: The metered shutter speed ranges for the Sekonic LiteMaster Pro L-478DR-U Light Meter for PocketWizard System is listed as 1/64,000 to 30 Minutes (1, 1/2, 1/3-Step Increments), Plus 1/400, 1/200. It depends on which increment you select as to which shutter speeds would be available. If 1/3-step increments is selected, then 1/160-sec shutter speed would be available. Refer to the instruction manual included with the light meter.

Q: 10. How to read candle per square meter (cd/m) using this unit?

A: Please see user manual: Ambient light Luminance (cd/m2 ) mode (by reflected light measurement using with accessory viewfinder available as separate purchase) Displays brightness values in cd/m2 units.
