Best Overall Flash for Sony A7RII: Sony HVL-F28RM External Flash  

The Sony HVL-F28RM is a compact and reliable external flash with flawless control. The flash is equipped with a face detection feature that can detect the natural skin tone of your subject. 

Sony External Flash with Wireless Remote Control,...

The external flash measures 2.56 x 3.28 x 3.59 inches and weighs 8 ounces. It is lighter than the Sigma EF-610 DG SUPER Electronic Flash and a bit heavier than the Pentax AF201FG Flash. 

The flash can cover up to 50mm focal length, so it can match the focal length of your lens. It also has a radio wireless communication system that lets you pair up the Sony A7II to another camera to serve as a receiver. It lets your cameras communicate with each other over long distances so you can cover more ground.  

With a guide number of 28, it can illuminate up to 28 feet, so you can give the much-needed light to the subject without having to be too close. 

Unfortunately, the wireless feature takes time to set up since you need to re-pair the Sony A7II camera whenever you change the receiver. 

Also, the hot shoe isn’t sturdy, unlike the hot shoes of the Sigma EF-610 DG SUPER Electronic Flash and the Pentax AF201FG Flash, so you need to be careful when you remove the flash or you might damage it. 

Pros: 

  • The flash is compact and is small enough to fit in your pocket, ideal for traveling
  • It is equipped with radio wireless communication so you can pair up two cameras to cover more grounds
  • The guide number of 28 is high; it can cover up to 28 feet

Cons:

  • The hot shoe is not solid

Best Sony A7RII Flash for the Money: Sigma EF-610 DG SUPER Electronic Flash

The Sigma EF-610 DG ST is the most powerful flash that Sigma has ever produced so far. The auto-zoom function of the flash sets the optimum illumination angle to match up the focal length of your lens, and it can cover from 24mm to 105mm.

The Sigma EF-610 DG ST measures 3 x 5.5 x 4.6 inches and weighs 11.6 ounces, making it heavier than the Sony HVL-F28RM External Flash and the Pentax AF201FG Flash. The flash has a built-in wide panel that can cover an extra 17mm so you can cover more ground. 

The head can be tilted up upwards up to 90 degrees and downwards up to 7 degrees for better close-up shots. It can also be rotated up to 90 degrees to the right and 180 degrees to the left so you can light up more areas.

The flash’s guide number of 61 is very high. It can illuminate up to 61 feet, unlike the Sony HVL-F28RM External Flash that can only reach up to 28 feet. With its auto power-off feature, the flash turns the LCD panel off automatically when not in use to save power.

However, the recycle time of the flash is slow as it takes 2.5 seconds before you can fire another round. Also, it does not have the Quick Shift Bounce feature that allows you to tilt from horizontal to vertical, so you can’t do fast flash position switches.

Pros:

  • The guide number 61 is high; it can cover up to 200 feet 
  • It has an auto zoom function so you can focus on your subject up to 150mm
  • It has a battery-saving feature called auto power-off

Pentax AF201FG Flash (Black)

With a measurement of 2.9 x 1.2 x 2.6 inches and a weight of 4.8 ounces, it is lighter than the Sony HVL-F28RM External Flash and the Sigma EF-610 DG SUPER Electronic Flash. 

The flash has a Quick Shift Bounce feature that can adjust the flash angle from 10 degrees to 90 degrees vertically to help enhance your photographic experience and allow you to get the best shot. The Sigma EF-610 DG SUPER Electronic Flash does not have this feature.

However, despite its power-saving feature, the Pentax AF201FG actually has a short battery life, which means you will have to change the two AA batteries often. Also, its recycle time is very slow as it takes 7 seconds before you can fire another round of shots. 

Pros:

  • The mode button is easy to operate and lets you switch to 5 modes easily
  • It is equipped with the Quick Shift Bounce feature for better angles

Guide Numbers

Using a flash with a high guide number can help you illuminate your subject at a certain distance. This feature is very useful when you are taking pictures in the dark. 

Basically, the higher the guide number is, the longer the distance at which the flash’s light can cover. For example, the Sigma EF-610 DG SUPER Electronic Flash has a guide number of 61, and it can cover up to 61 feet. You won’t have to stand too close to your subject just to capture a clear image.

Weather-Sealed

Photographers usually do photoshoots outdoors. Although it could offer more beautiful and natural subjects like mountains, trees, animals, insects and more, you are exposed to unpredictable weather. 

A weather-sealed flash is important because it lets you continue taking pictures despite the rain, harsh wind, or snow, and you won’t have to worry about your flash’s condition. 

If you are looking for a flash that can withstand any weather, you can get the Pentax AF201FG Flash, as it is the only flash on the list that is weather-sealed.

Recycle Time

The recycle time is the time that the flash needs to be able to gather enough power to do another round of shooting. All flashes have recycle times, however, some are faster than others. 

The reason why flashes have recycle times is because of the amount of power that they give off when the light on the flash’s head bursts. It needs to replenish and adjust before it gathers another set of energy from the battery. 

A flash with a fast recycle time lets you capture more images without having to miss a single precious moment. Out of all the flashes on the list, the Sony HVL-F28RM External Flash has the fastest flash time of 0.1 seconds.

Frequently Asked Questions

How is the TTL Mode Different From the Manual Mode?

The TTL mode, which stands for Through The Lens, is different from the manual mode because the TTL mode reads the exposure going through the lens of the camera and uses the metering system to estimate your distance from the subject before it flashes. TTL is equivalent to automatic mode on your digital or mirrorless camera.

Meanwhile, the manual mode offers you more control because you are the one who gets to choose when you want to flash the subject and how much light is exposed on a shot. 

Are Nikon and Canon Flashes Compatible on a Sony Camera?

Nikon and Canon flashes are not compatible with any Sony camera. Sony has a built-in multi-interface hot shoe that unfortunately does not work directly with Nikon and Canon external flashes. 

However, there are third-party brands that work for Sony cameras, such as Stigma and Pentax, that fit well with Sony’s features and hot shoes. 

Conclusion

Most modern cameras are already equipped with built-in flashes. However, attaching an external flash can give you better results and it can increase the quality of your images and videos.

The best flash for Sony A7RII can improve the lighting no matter where you are, and it helps you take consistently clear shots in different environments. With the right external flash, you can capture numerous precious moments.
