The Sekonic L-308S meter is by far their most popular light meter. Fairly basic but very accurate and affordable, it’s the model that often introduces photographers to light meters. Perhaps they may eventually step up to something fancy like the L-478 or L-858, but the L-308 is usually where they started and the one they recommend to new photographers looking to get their first meter.
Now, in the form of the Sekonic L-308X-U, Sekonic have combined the best features of the L-308S for photographers and the L-308DC for filmmakers. The L-308X-U is a single unit designed for the next generation of both photographers and filmmakers. It also includes a couple of new, often requested features, too. Like a backlit LCD and ISO850 setting for modern cinema cameras.
