HVL-F58AM Wireless IV

Wireless Flash with the HVL-F58AM using A-700/A-900

3- Wireless Ratio Control Option Chart

Here is a chart that we have created to summarize the use of the Ratio flash settings in the two modes available – CTRL 1 & CTRL 2. The setup has been verified with actual flashes.

As we can all see from the chart above, to utilize the flash controller HVL-F58AM in a three group controller controlled Ratio flash setup, minimally two HVL-F58AM are required as the HVL-F58AM is the only flash in the alpha flash system that could be set to the RMT2 (Remote Group3 )mode.

The lowest cost for a three flash controller controlled Ratio flash setup would be two HVL-F58AM where one is a controller and one as RMT2 + one HVL-F42AM as RMT (Group2).

The HVL-F20AM wireless trigger flash is now available in the market. A review by alphastrobist.com will be available soon.

    Dear Sulhan,

    Loved this little tutorial!! Extremely helpful.

    I need a little help. Have you tried using the new “Sigma EF-530 DG Super flash for Sony” in similar wireless setups?? … If yes, can you tell me which controler mode of the Sony 58AM would support the Sigma EF-530 flash as its slave (remote)?

    I am using Alpha A300, and I own a Sony HVL-F58AM. I’m thinking of buying a Sigma EF-530 DG to expand my range of flashes. Your answer will help me to make a decision.

    Looking forward to your response.

    Hi Sulhan,

    Very nice tutorial.

    I need your help here. Have you tried to remotely control the ratio of the “Sigma EF-530 DG Super for Sony” with “Sony HVL-F58AM” in similar wireless setup?

    I already own a HVL-F58AM, and I’m planning to buy a Sigma EF-530 DG Super for Sony. But I need to know if I can use the Sigma off-camera wirelessly and as a slave to the 58AM, which will be sitting on-camera as master, and do the ratio control.

    Also, please do a review on the Sigma flash, and comment if the Sigma can do TTL off-camera wirelessly. I read somewhere that the Sigma only does ADI for Sony, and so the Pre-Flash TTL does not work when the Sigma is off-camera. I may be wrong, so please confirm.

    Looking forward to you response. Your answer will help me make the decision on buying the Sigma flash. Thanks in advance.

      Hi Saiman,

      I have not personally try out the Alpha 58AM flashes to work together with the Sigma EF-530 DG Super. I will put up an update if I have the opportunity to test out if i get hold of one of those flashes.
