Sony A6300 Flash

Coverage and Range
A fairly weak flash with very narrow and uneven coverage at wide angle. Our standard indoor portrait shot required more than average exposure compensation and still came out dim.

Coverage. Flash coverage is very narrow and uneven at wide angle (16mm), leaving very dark corners in our flash coverage test image. We no longer test at full telephoto is coverage is invariably better, making wide angle the worst case.

Exposure. Our Indoor Portrait test scene came out a little underexposed even with +1.0 EV flash exposure compensation at ISO 200, and positive flash exposure compensation had no effect in our tests. The average amount of flash exposure compensation required for this scene is +0.7 EV, so the A6300's built-in flash performed a bit below average here. The camera's Slow-Sync flash mode produced very bright results with no flash exposure compensation, though with a strong orange cast from the ambient room lighting because of the slow shutter speed.

Manufacturer Specified Flash Test. The Sony A6300's built-in flash is rated with a Guide Number of 6 meters or 19.7 feet at ISO 100. That works out to about 7 feet at f/2.8. In the test shot above, the A6300's flash produced a good flash exposure at those parameters, which confirms Sony's flash power rating is credible.
