Yongnuo YN320EX S TTL Flash for Sony Cameras

Yongnuo YN320EX S is a mini flash unit designed specifically for Sony mirrorless cameras. Key features include its compact design, 2.4 GHz wireless transmission and full compatibility with other units in the Yongnuo Wireless System. Unlike many entry-level flashes, the YN320EX S can function as both a master and a slave unit, with support for 6 groups and 16 channels. It uses just two AA batteries, which can produce up to 220 flashes at full power.

Yongnuo YN320EX S is fully compatible with Sony’s through-the-lens (TTL) metering for automatic exposure control and supports HSS. TTL flash metering greatly simplifies the process of using off-camera flashes, especially when multiple units are involved, while high-speed sync enables the use of flash at shutter speeds up to 1/8,000 second. Yongnuo YN320EX S is without a doubt one of, if not the best budget-friendly flash for Sony cameras on the market right now.

As a radio master unit, YN320EX supports controlling up to 6 groups. It can remotely control the flash mode, flash output, focal length, number of stroboscopic and stroboscopic frequency of slave units. As a slave unit you can use numerous Yongnuo speedlites like Yongnuo YN685, YN560III, YN560 IV, YN660 etc.

YN320EX S supports High Speed Sync up to 1/8000s as well as full FEC and a guide number of 31 (ISO 100, 105mm). Also it has excellent heat dissipation technology to help prevent any issues with overheating. The Yongnuo YN320EX S comes in at only 225g of total weight making it pretty light considering how cheap it is as well as how robust it is. On top of this, the flash unit is only 1.57 x 6.06 x 2.56″ / 40 x 154 x 65 mm making it very small considering the massive amount of featured available, as well as its excellent performance too. This allows you to add it to your bag of camera accessories without having to take up much space making your life easier.

The flash offers 22 stages of power output allowing you to tweak the output of the flash to meet the needs of your specific session with ease. The 0.1 to 2-second flash recycle time and 1/350 to 1/20000 second flash duration allow you to further tweak this to ensure that you are able to get exactly what you require out of the flash during use for specific types of photography. Overall the YN320EX S is a solid flash unit for under $100 that is well worth investing in due to its excellent performance and functionality.
