The Meike MK320 system flash is designed for Nikon camera systems and features TTL functionality for automatic exposure control. This compact and powerful flash achieves a guide number of 32 at ISO 100 with eight power levels adjustable in 1/3 stop increments for precise exposure control. The flash head can be rotated and tilted for bounce flash applications, allowing photographers to position the light effectively. An integrated LED lamp provides continuous light for video recording or subject illumination up to two meters. The device is powered by two AA batteries and has a Micro-USB port for directly charging rechargeable batteries. Multiple flash modes include a strobe function for capturing motion sequences in a single image, as well as S1 and S2 modes for off-camera flash synchronization. The S1 mode triggers on the first flash of the master flash, while the S2 mode ignores pre-flash signals for compatible wireless triggering systems. A backlit LCD display ensures clear visibility of settings under various lighting conditions. The flash automatically enters sleep mode after sixty seconds of inactivity to conserve battery life and instantly reactivates with a button press. With dimensions of approximately 70 mm wide, 110 mm high, and 80 mm deep, this black flash unit weighs about 300 grams without batteries. The integrated design combines professional flash capabilities with portable convenience for photographers needing reliable supplementary lighting in various shooting situations.
