  1. Gret small flash! Now i just hope that Sony will add the ability to use the wonderful led light of that new flash as an external AF-assist for low light situations considering that all the G-master lenses cover the small in-body af light!! The same vay as the the Olympus FL600-R does.

  2. Hi Brian, would you recommend this flash for someone shooting on the A7Rii and Zeiss 55mm f1.8? Relatively new to the flash photography game so think this could be a good option for a native & compact kit to be ready for great portraits wherever I am. If I pick up a 135mm lens in the future will this flash work with it?
    Cheers!

    1. Yes. This is the first radio wireless flash from Sony so it’s the future – not the past. It will work properly with Sony, Zeiss and Canon 135mm lenses. I’m not certain TTL will l operate properly with other brands.

  3. Hi Brian, Do I understand correctly, that for off-camera flash, I need the Wireless Radio Commander (on my A7m2) and those two components should work? IOWs, I don’t need the Wireless Receiver on the HVL45. I’m having difficulty ‘pairing’ I think… I’m familiar with Nikon’s optical system, I’m stumbling with Sony’s system. Thank you…

    1. Thank you Brian. I’ve paired the Radio Commander and the HVL 45 successfully, but I get the error message “This accessory is not supported by the device…” when I try to take a photo. One post suggested drying the contacts, which I’ve done (I don’t think they were wet or soiled to begin with) and still get this message.

      I’m frustrated with Sony in that the documentation in the HVL 45 box, was very basic, it certainly did not even covered all the features of the flash, except to identify them. I’m at a loss and now wondering if my flash is defective, though logic would dictate that I’m probably at fault for missing something. Any suggestions?

      1. That message usually means there is either a problem with the contacts on the device (unlikely Sony nice its new – yet possible) or with the contacts at the front of the MI shoe. Either moisture or debris could be the culprit. Try keeping the hot shoe cover on whenever the MI shoe is not in use.

  4. Thanks so much for the reply Brian. I have been putting off the firmware upgrade, but used your guide and voila! My camera shipped with 3.1, now current with 3.3. Your Bulletproof Guide was just the help I needed – thank you so much!

    Hello Brian,
    Plan on getting the Sony HVL-F45RM for my Sony A7Rii. Quick question, if I bounce this flash can I use with HSS?
    Thanks,
    Oliver

  6. Hi Brian,
    With the firmware 4.00 update for the A7Rii, does this mean the LED on the HVL F45rm will work like a focus assist light on the body?
