Priolite Gives Pentax Users High-Speed Sync

Relatively new to the professional flash world, German strobe manufacture Priolite is wasting no time in making a name for itself in the big leagues. Their latest product, the RC-HS/P, is a transmitter/controller for their lights that enables high-speed sync (HSS) with the Pentax line of cameras, and most excitingly, Pentax’s digital medium format 645Z.

The Pentax 645Z has been atop the review list for many people, but its weakness compared to its medium format brothers has been the relatively slow flash sync speed, which is limited to just 1/125 of a second. Prioite is changing that with their new controller which will allow users to sync at up to 1/4,000 of a second with the 645Z, and 1/8,000 of a second with Pentax DSLRs. An important detail is that those sync speeds are available at any power setting on a Priolite strobe. Thats not even something Profoto can say about their B1 or B2 series.

Pricing is set to be $273 for the transmitter, or you can get a set that includes the transmitter, a MBX500 (which is their 500W/s strobe), and some other basic accessories for $1,970. Seeing as Pentax users are left out of the wireless TTL control by some of the other big flash manufactures, this could be a game changer for them, specifically in the medium format market where a potential customer could have passed them by because of the limited sync speeds. I would personally love to test this combo out in the field, and see what the workflow is like.

no offense to priolite at all, I’m glad to see a possible solution out there… but I sure would like to see pocketwizard get involved with a solution for the 645z to work with the strobes I already have. But back to the priolite…does it allow for rear curtain sync for the 645z as well?

Hey Joseph, I would love to see pocket wizard figure something out as well. Or for Profoto to expand its offerings to other brands as well with their air remote/HSS system. I didn’t see anything about rear curtain sync in all of the research I did, but It might be something you can configure within the Pentax menu itself.

not that I found. I’ll have to read through the manual again but on I didn’t find anything for rear curtain sync. Just one more opportunity lost to use the 645z…back to the 1D-X! Been really frustrating that I can’t use the Pentax when I want to.
