HSS on RF 60

Can i use the V6 to turn on HSS on a RF60?

Thanks :-)


  • No, you have to enable HSS on the flash directly (with two button presses). After that, you can fire the RF60 in HSS mode using a V6.
  • Why is it that I have the HSS enabled on the RF60, and Optical Slave disabled, but when I shoot at 350 shutter speed (a stop above my camera's maximum 250 flash sync speed), using the V6 - there is a black band at the bottom? 

    I thought that you can fire the RF60 in HSS mode using the V6.
    I use a Nikon d750.

    As you see Class A's above reply, the answer is a no unfortunately.

    The "HSS" mode on the RF60 uses optical slave and you need a TTL flash
    to send out a pre-flash signal.  We call this "HSS Sympathy Mode".

    V6 on its own cannot trigger an RF60 and correctly sync above x-sync speed.

    The black band is aka banding issue and it happens when flash was fired above camera's maximum x-sync speed.

    FYR, here's another discussion on HSS with RF60:

    To help us better help you, always state the exact firmware version installed on your Cactus device(s), such as: "1.1.013", "FUJ.1.002", "NIK.A.001", "v.103".

    For the time being, Cactus V6 (MK1) running on firmware version 2.1.001 can be triggered by a V6 II (MK2) running on Multi-brand HSS firmware (e.g. 1.1.013) but not by X-TTL firmware versions:  PEN.A.001 NIK.A.001 OLY.A.001.  No schedule has been released yet for an "A" version firmware on the V6 (MK1). 

    Cactus RF60X / RF60 Firmware versions A04 and A03 currently ONLY works with PEN.A.001 NIK.A.001 and OLY.A.001.  Other "A" version of X-TTL firmware will be released soon. For both Multi-brand HSS and X-TTL firmware versions (FUJ, SIG, SON), install firmware version 103 / 205 on your RF60X / RF60.
