TTL pass through and Metz AF64-1 for Sony

edited December 2015 in V6 Compatibility

I understand the cactus can't control the Metz AF64-1 for Sony remotely but will it work when mounted on top of the cactus for TTL pass through?


  • There is no TTL pass through for Sony as the V6 is not using Sony's Multi Interface Shoe. 

    In other words, there is only the centre hot shoe pin that is "passing through" the V6 between the Sony camera and flash, and that is for basic flash triggering signals only.

    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.

  • Thanks Antonio. I was going to ask about Sony flash support but saw on another thread where you confirmed that Cactus was working on it.

    Any rough timeline estimates and is there a place where I can sign up to get updated when this becomes available?
