Watch out for

  • The 4030 V2 has its own holders (101-63-4030V2-ZC69 and 101-63-PXL43V2-SMM65); they are not the 4040-PRO's ZC65/ZC69.
  • Genmitsu lists the 4030 V2 for the V2 water kit's signal cable only, not as a mount or payload approval.
  • Genmitsu's product page does not name the stock holder size, so measure before buying a dust shoe.
