Our 10 Best Flash For Sony a7iii and a7riii

Putting in a hefty amount of hours into our research, we have chosen each product with compatibility and quality in mind. Let’s get right to it!

1. Neewer NW320 Mini TTL Speedlite Flash Automatic Flash

Neewer NW320 Mini TTL Speedlite Flash Automatic Flash

To start off our list, we have the NW320 from Neewer, which is undoubtedly up there with the greats.

The flexibility of this external flash is what makes it so desirable. Compatible with the MI Hot Shoe DSLRs and also the mirrorless series from Sony.

Neewer have really packed in quite the punch in this tiny little device. Weighing in about 150 grams and almost the size of an average palm, carrying this flash won’t take up unnecessary space.

Featuring an LCD display with buttons on the side and bottom, this flash is easy to operate.

The crisp contrast of the display keeps the text and numbers clear so you can see them clearly, even in broad daylight. So, it’s pretty evident why it’s seen as the best flash for Sony A7III.

The rotation angle of the NW320 will let you bend it to absurd positions. This can be quite useful when you need to twist and turn the flash to click an object at an angle.

Having a rotation angle of 60 degrees to 90 degrees allows you to turn the flash entirely to one side of your camera.

What’s more, it also comes with a vertical rotation angle of -7 degrees to 90 degrees.

This enables you to control the vertical angle of your flash in order to capture photos above or below you. Neewer has integrated one of its high-quality LED-lights into this pocket-sized device.

At this point, we were just thinking, how far can they go? But they’ve done exceptionally well with the selection of features.

The LED light is a great addition for those of you who take short clips to make lightweight movies or just capture memories.

Starting off, out of the box, you will notice the solid build of the NW625. Made with high-quality plastic, the device has a total weight of 402 grams.

But don’t take your eyes off it, because you will then notice the tons of other benefits you get from it. The flash head comes with a built-in reflector and wide-angle diffuser.

This will unlock two different shooting modes, one with focused lighting and the other with soft lighting.

Using the reflector allows you to reflect the light on to the subject in order to make it brighter. The wide-angle diffuser, however, is used to spread out the light to give you softer pictures.

And this is ideal for photographers that specialize in capturing movements like sports.

The multi-flash feature will let you get the right detail even when your subject is moving at high speeds. This saves you time and also allows you to capture the moment as it happens.

Things to Consider Before Buying Flash For Sony a7iii and a7riii

Before you rush to the store or visit your favorite shopping site, there are certain things you need to take into account.

These features will allow you to judge your choices better and choose the best flash for Sony A7III and A7RIII.

Adjustable Temperature

External flashes are large devices that use up quite a bit of power. This, in turn, causes them to heat up, which is why you should always look into the temperature control specs of the flash.

The hotter the flash, the harder it gets for you to hold it out. This can be an issue for those of you who need to cover events or take pictures for long periods of time.


Whether you’re a big spender or not, flashes come at a costly price. And so, you will always want to invest in one that will last you for the long haul.

The customer service quality and warranty service of the brand you choose will directly lead to a long-lasting purchase.


As we’ve mentioned before, investing in an external flash requires some thinking. The brand is one of the categories where you need to go right.

Choosing a renowned brand will most likely give you a higher sense of confidence in going for your purchase.

What’s more, the quality of the brand you choose will allow you to get the most out of your flash.

Some brands are more focused on providing maximum features, while others put a close eye on durability and stability. Choose one that suits your style best and go for it.

GN Value

GN or guide number is how we measure the power of the external flash. You should always take a close look at the GN of your flash in order to get an idea of the power levels you’ll be experiencing.

And you should consider trying out flashes with different GN numbers. This will help you get a clear idea of what your preferred power level is.

For the A7 III and A7RIII both, you can use flashes that have a power level (GN) of 36m/157 ft. This should be fine for those regular shots if you’re not going too fancy.

Whatever the case, the larger the GN number, the brighter the light hitting your object.

Recycle Time

When we talk about recycle time, we mean the lag period between taking each photo. While using an external flash, you need to go for low recycle times to take photos in quick succession.

The importance of this feature depends entirely on your mode of use. If you are covering live objects that need fast shutter speeds, getting a flash with a recycle time of 0.1 to 2.2 seconds should do the trick.

Auto Focus Beam

The Autofocus and zoom settings of a flash must be well calibrated with your camera. For excellent pictures, you will need to be able to adjust your flash levels based on the zoom and focus.

We must inform you that an assist beam is required in order to support the external flash system. This also gives you the added benefit of being able to click pictures in very low light.

Other’s Opinions

It is always a good idea to ask around and get people’s opinions on a product. If you’re someone who is well connected with photography communities, don’t be shy to ask around.

Preferences are different for every person, and getting their insight on products will help you decide on what qualities you should prioritize.

If you’re someone who is starting out, you can check out the customer reviews on online sites. The ratings and reviews are mostly in-depth, giving you a better concept of the product and its offerings.


Before engaging in the research process, deciding a budget is one of the first things you should be doing. This will narrow down the list of products you should be looking into, allowing you to judge each option closely.

It would be a waste of time if you spent hours shortlisting products that are above your budget range. Instead, decide on the budget and then move into shortlisting your options.


When we talk about compatibility, we aren’t talking about the flash and your camera. All of the products listed above will easily accompany the Sony A7III and A7RIII.

What we were actually talking about is the ability of your flash to join with other devices.

Many external flashes can act as the master system and control other flash devices. Alternatively, they can also be compatible with other flash devices and act as the slave unit.

Frequently Asked Questions (FAQs)

Here we have the most commonly asked queries regarding the best flashes for Sony A7III and A7RIII:

1. Why might I need a reflector card?

Using a reflector card lets you redirect any form of light from the surrounding onto an object of your choice. This makes your pictures brighter and gives a natural form of lighting.

2. Can I charge my flash using the micro USB cable?

Some external flashes allow USB recharging with replaceable AA batteries while others have built-in rechargeable batteries.

Most flashes, however, use regular AA batteries, and so you must check with your brand to see if it supports USB charging.

3. What is the benefit of a wide-angle diffuser?

Using the wide-angle diffuser lets you spread the light from your flash to distribute it more evenly across your object.

4. Why might some flashes require two batteries instead of 4?

Flashes with low power levels will serve you for longer hours with 4 batteries instead of 2. For larger guide numbers, you should always try to choose a 4-battery setting.

5. Can I click pictures in quick succession using the flash?

That depends entirely on your recycling time. All flash systems have a designated range of recycling time, which is usually a matter of seconds.

Final Words

Investing in a good flash is definitely one decision that needs to be well thought out. Starting from the price range to your preferred features, you must look into them all.

Whether you’re an amateur or professional also influences your choice. You may not need a very high powered flash when you’re just starting out. But for professionals, you need to have auto-zoom functionalities and a high GN.

We truly hope the list above will help you judge your options critically and pick the best flash for Sony A7III and A7RIII.
