Most recently, I was looking for a compact flash for my Sony a7 III as it can be useful in various situations, for example, to get a more balanced color during daylight or as a controller for other flashlights. I created a list of my flash units which I would consider to buy (have not tested them).

Best compact flash for Sony a7 III, a7R IV a9 II or a6600

Sony HVL-F45RM

weight: 318 grams / 11.2 oz.
recycling time: 2.5 sec.
batteries: 4 AA

The Sony HVL-F45RM is probably the first choice if you have already a Sony camera. It can operate as a radio wireless receiver or commander beside sitting on your camera. Further, it can wirelessly support 15 units and comes with a dot-matrix LCD. The flash can also be tilt from -8 to 150° and rotates left and right to 180°.

Aputure AL-MX

The Aputure AL-MX is the smallest camera light from Aputure and offers a 30% boost kick over 60 seconds interval if you are when you might need more light for a shorter period. One benefit of this light is that I can charge it through is USB port which might come handy especially if you have a USB Power Bank with you.

The video light comes with 128 LEDs, has a beam angle of 120 degrees and a color temperature range from 2800K to 6500K. However, if you need a more versatile light, then I would rather recommend the Aputure F7 over this light even so it weights more.

You can buy the Aputure AL-MX on Amazon.

Aputure F7

The Aputure F7 is the light that I am using myself. Similar to the Aputure AL-MX I can charge it through its USB port. You can also power it with a Sony NP-F battery attached to its back. The F7 comes with 256 high-CRI led lights, has a beam angle of 45 degrees, and a color temperature range of 3200K-9500K. I can adjust the brightness of the F7 from 1 to 100%.
