Cactus V6II Wireless Flash Transceiver – – FINALLY: HS Sync with Pentax medium format and off-brand flash systems

Good, work with my pentax 645z. I mainly use these on studio strobes using a sync cable and they work fine. The option to use some non propriery flashes off-camera is great.

Don’t make the same mistake as myself and think this unit can trigger a flash such as canon 430 remotely similar to the canon remote flash trigger. It can in fact not speak the canon protocol. You need to buy one of these for each flash you wish to trigger and hook the flash onto it. The cactus units then speaks among one another and disregards the canon remote trigger protocol altogether. In short, having just one of these units is totally useless. Here are the specifications for the Cactus V6II Wireless Flash Transceiver –:

  • Enter your model number

  • Two High-Speed Sync Modes
  • AF-Assist
  • Highly Intelligent
  • Cactus V6II Wireless Transceiver

Finally: hs sync with pentax medium format and off-brand flash systems. I ordered two cactus v6ii units as a cost-effective method of using a pentax medium format system to trigger a variety of flash sources at speeds above the pentax x speed of 1/125th. Prior to the v6ii and a recent firmware update from cactus, the only methods of shooting above 1/125th with flash on the pentax was to use pentax flash guns, or buy into an expensive monolight system which uses a remote reporting itself to the camera as a pentax device. I didn’t want to spend on yet another flash system, so the pentax remained an inflexible friend. The v6ii has changedthat situation, and i am now happily shooting up to 1/4000th with both 645z and 645d bodies, using the latest cactus firmware 1. The v6ii is working with ad360, ad600, and ad200 units from godox, as well as my elinchrom ebl 400 and hs 1000 systems, each allowing hs sync with the pentax or my nikon and sony bodies. Firmware updating is surprisingly straightforward and speedy, using the cactus update app for mac os. I intend to buy a third v6ii, as a backup, in due course. A caveat is that one of my v6iis refuses to work as a transmitter unit, so there are probably some quality control issues to consider.

Reviews from purchasers :

  • Good, Work with my Pentax 645z
  • I found the Wireless trigger to do every thing it
  • FINALLY: HS Sync with Pentax medium format and off-brand flash systems

Very temperamental with lots of quirksyou need to update firmware often.

I found the wireless trigger to do every thing it. I found the wireless trigger to do every thing it said it would. Delivery was quick and well packaged. Instructions could do with being a little clearer, but once sorted it works very well. So if you need a flash trigger try the cactus v6ll.

Works flawlessly to give me ttl flash metering and hss sync upto 1/8000 sec on a fuji x-t2 with a canon 580 ex flashgun. Poor instructions, both the included leaflet and the on-line manual. However this is of little consequence as the product works and feels well made.
