There are three differences to the Cactus system:
- HSS is possible without using an HSS-capable flash for triggering or using remote shutter release.
- The lights are a lot more powerful.
- The prices are much higher.
Another probable difference is that the PrioLite system introduces a P-TTL based (pre-flash) delay. While the strobes will not issue a pre-flash, the timing will most likely be that of P-TTL.
A manual system, like the Cactus system, does not introduce such an exposure lag.
With a
Cactus V6 trigger and
Cactus RF60 flashes one can also use shutter speeds up to 1/8000s.
Normally this requires the use of an HSS-capable flash for triggering purposes but one may also use a
remote shutter release technique that only requires a cheap shutter release cable.
The techniques referenced above can be used with any lighting equipment that supports manually engaging HSS mode, such as the Cactus RF60, to achieve HSS lighting, but it can also be used with any lighting system to achieve HyperSync, i.e., using the relatively long duration of a full power flash to illuminate the full frame at any shutter speed.
While I welcome the new Pentax support from Priolite, I don't think it will have a large impact on most Pentaxians due to its pricing structure. I'm hopeful that similar, alternative solutions with more palatable pricing will become available to Pentaxians soon.
