Cactus Enhances Wireless Flash Capabilities for Pentax

The Cactus X-TTL system, which unifies control across different flash systems, recently added support for Pentax cameras and flashes. Pentax shooters can now enjoy wireless P-TTL when pairing Pentax flashes with Cactus triggers, and can also remotely adjust the power and zoom of other flash systems and trigger them without needing wires or an on-camera flash.

Features available to Pentax shooters using the Cactus V6 II transceiver include:

  • Wireless P-TTL support for Pentax system flashes and Cactus RF60 and RF60X flashes
  • Wireless manual power and zoom control with HSS/FP support of Pentax, Canon, Fujifilm, Nikon, Olympus, Panasonic, Sigma and Cactus wireless flashes
  • Rear-curtain sync both on- and off-camera
  • Multi-master control of the same set up flashes by up to 20 different cameras
  • Independent control of up to four groups of flashes plus on-camera flash
  • Automatic flash power compensation for changes in aperture, shutter speed or ISO
  • Wireless camera shutter release with an additional cable

PentaxForum members have already reported their hands-on experiences with the X-TTL system in the Flashes, Lighting, and Studio forum. You can also learn more about flash photography in The Pentax Digital Camera Flash Lighting System, a practical guide written by our own Nigel McGregor.

The Cactus X-TTL system is rapidly maturing. Since announcing support for Pentax on November 7, 2017, Cactus has already added support for Micro Four Thirds system flashes.

The Cactus V6 II transceiver is available from B&H Photo.
