What to Compare Before Buying
- Camera compatibility: The key check for this flash is whether your exact Sony body is named as compatible. The listed exclusions also matter if you use an older or different Sony model.
- TTL versus manual control: This model offers both modes. Compare that with the way you prefer to set flash output.
- Power and charging: The built-in lithium battery, USB-C charging, 1.5-second recycle time and stated 700 flashes per charge are the main power points to compare.
- Adjustment range: The flash output adjustment runs from 1/32 to 1/1. Check whether that range suits the lighting control you want.
- Accessory use: Magnetic add-ons are part of the appeal, so check whether you want to use diffusers or colour filters with the flash.
Compatibility, Size and Fit
This flash is aimed at Sony cameras, with a strong focus on the ZV series and selected Alpha bodies. It is named as suitable for compact cameras such as the ZV-1, ZV-1 II and ZV-E10, and it is also listed for several other Sony models.
Because compatibility is central here, confirm your exact camera model before choosing an offer. The named incompatibilities are just as important as the compatible models when avoiding the wrong version.
What Else You May Need
If you plan to use the flash on a supported camera, no extra camera system is named as required. If you want to use the magnetic lighting accessories mentioned, check that the selected offer includes the accessory set you want.
