Sekonic Litemaster Pro L-478DR-U-EL Exposure Meter

I wont start this post by saying I have bad luck. That is not this case. I just rarely have good luck. I don’t find money, I don’t win on lottery tickets and when I buy something it usually shows up cheaper shortly thereafter. Well for once I can say i was lucky and the good luck is the subject of today’s post the Sekonic Litemaster Pro L-478DR-U-EL exposure meter.

About two years ago I purchased the standard model L-478 and it was a game changer for getting proper exposure of my pictures. Life was good. Fast forward to last year when I decided to bite the bullet and buy a real studio strobe in the form of an Elinchrom D-Lite RX-4. I found the D-Lite RX-4 to provide great results but my control was limited to using a pc sync cord connected to my Nikon D810. I found myself at a crossroads with studio lighting. I was heavily invested in the Nikon CLS but it’s proprietary system does not work with non Nikon flashes. There are third party trigger controls like pocket Wizard, RadioPopper and a bunch of inexpensive knockoffs. I finally decided I would head down the path of Pocket Wizard as it was the most common radio trigger brand. Now up until this point I had basically ruled out Elinchrom’s own radio trigger system referred to as EL Skyport. This was because it was becoming a dated system. Then something changed. Elinchrom updated the line. Elinchrom Skyport became a cross between Nikon CLS and Pocket Wizard. With the purchase of a EL- Skyport Plus HS transmitter I could communicate with my D-Lite RX-4. The EL- Skyport Plus HS is the Elinchrom equivalent of the Nikon SU-800 Commander with a big improvement. If I also purchase an Elinchrom EL-Skyport Receiver Plus for Nikon I could also trigger my Nikon Speedlights. This was huge for me. I was now on the path to officially adopt Elinchrom Skyport to radio trigger all of my flashes. What does all this have to do with the Sekonic Litemaster Pro L-478DR-U-EL? Keep reading.

Right about the time I made the decision to switch to Skyport radio triggering Sekonic announced an Elinchrom version of the L-478 that had been upgraded to fire Elinchrom strobes.This was about an ideal solution to exposure as I could dream for. The problem was I had the year old standard L-478 that cost me $400. I simply couldn’t justify another $400. While I briefly thought of selling the L-478 I knew I would procrastinate and never follow through. Then something happened, I got lucky. A friend was visiting and we were discussing all that I wrote above and I went to Amazon to show him the Elinchrom version of the L-478 and what do my eyes see? It’s on sale for $299 and thats $100 less expensive than all the other versions of the L-478. I bought it.

So now your thinking “What the heck will he do with two exposure meters?”. That’s the best part of it all. I can leave the Skyport version of the Sekonic in my studio and the regular L-478 can stay in my camera bag. I have further refined my setup that the Nikon speedlights and the CLS will be my portable setup and I will continue adding Elinchrom strobes with their built in Skyport receivers to my studio setup.
