Best Overall Flash for Sony a7 III: Sony HVL F32M MI 

Sony HVLF32M MI (Multi-interface shoe) Camera...

The Sony HVL F32M MI flash has a retractable design that is very compact and suitable for outdoor photography with the Sony a7 III. The F32M is not durable due to the presence of holes in its construction.

The flash may also be used wirelessly, suitable for Sony a7 III. The built-in diffuser softens the flash’s brightness and prevents harsh shadows from appearing on your photographs.

Pros

  • Has a tilting/swiveling head that lets you bounce the light from ceilings and walls to get softer lighting effects than a direct flash would give
  • Comes with a unique reflector card, which you can set up to cover half of the flash head, thereby preventing it from emitting too much light from one side of a photo

Cons

  • Flash doesn’t rotate left and right, so you need to rotate your camera if you want to change its angle
  • At 8.3 ounces, the HVL F32M is heavier than the Sony HVL F20M, which is smaller, lighter, and easier to transport

Best Flexible Flash for Sony a7 III: HVL-F28RM

The HVL-F28RM also boasts a high guide number of 28, which is more than adequate to illuminate portraits or other subjects up to 30 feet away. It supports high-speed sync (up to 1/8,000 second), back curtain sync, wireless control, and auto zoom with focal lengths ranging from 24mm to 105mm.

In addition, the F28RM includes an adjustable angle that may be reduced to 10 degrees for close-up photos. This flash is also dust and moisture resistant, so you may bring it with you when shooting in difficult conditions.

Pros

  • Flash also comes with an LED light useful for video recording in dark environments
  • You can tilt the flash head down to -10 degrees and up to 150 degrees, giving you more flexibility in your lighting setup, especially when using an umbrella as a modifier
  • Swivel mechanism in HVL-F28RM is also much more solid than the plastic swivel mechanism found on the HVL-F20M flash

Cons

  • No autofocus capability, so you need to manually focus in low light conditions when taking photos
  • Not enough power for outdoor use on a sunny day

  • Compact, reliable and made by Sony for flawless flash control

Best Lightweight Flash for Sony a7 III: Sony HVL F20M

Sony HVLF20M, MI Shoe External Flash for Alpha...

The Sony HVL F20M is a small and lightweight flash that makes it friendly for lengthy shoot times. This flash takes 2x AA batteries, so you won’t have to carry around extra rechargeable lithium-ion batteries to power it.

It isn’t nearly as flexible as the HVL F28RM. You can’t rotate or tilt the head on the HVL F20M, so it’s unsuitable for bounce flash photography.  You can control this flash from your camera using wireless communication, which means you don’t have to have line-of-sight to use it.

Pros

  • HVL F20M will provide more power than HVL F28RM, and it has a built-in LED video light that you can use when shooting in live view
  • Flash has an impressive 100mm coverage range with a guide number of 20

Cons

  • Challenging to change the battery without removing the flash from the camera
  • No flash diffuser built-in, so you will likely need to buy one to soften the look of the light

  • Extends flash range beyond camera's built-in flash
  • New Multi Interface shoe for expanded compatibility
  • Bounce flash enables shadow less indirect lighting

Bounce Flash Head

The bounce flash head is an essential feature for photography. The HVL F32M flash head can tilt and swivel around to be off a wall or ceiling, which helps eliminate harsh shadows.

This gives your subjects softer lighting and more natural results, excellent for portrait work. Even though this might not be useful for every type of photo, it is still helpful for most of them and should be considered when buying a flash.

Guide Number

When a flash has a high guide number, it will provide more light. This means you will illuminate your subject more, and the background will be brighter. If you’re taking pictures of sunsets or anything where lighting is essential, then ensure your flash has the right amount of power.

The higher the guide number, the more influential the flash, like the HVL F28. The GN is usually listed in feet or meters depending on where you are, so make sure you convert if necessary. Unlike the HVL F32M, the Sony HVL-F28RM has a Guide Number of 28 and is designed to be used with a Multi-Interface Shoe camera.

Tilt-and-Swivel Head

The HVL F28 tilt and swivel heads help you point your light in any direction you want. This enables you to create exciting lighting effects for your images. You can even bounce light off ceilings or walls for softer and more natural-looking light in your pictures.

E-TTL

This feature allows your camera to automatically determine how much light should come from your flash based on information from its light meter. It’s convenient and generally does a good job. If you have an older camera or flash unit, it may not support E-TTL technology. In this case, you’ll need to manually adjust your exposure settings each time you use your flash.

Adjustable Temperature

Make sure that the flash you choose has an adjustable temperature. This feature allows you to change the color of your light and achieve a warmer or cooler tone. The HVL F20M has an adjustable temperature setting so that you can get the perfect color balance for your photos.
