Review on Wireless Remote Shutter Compatible For Sony Alpha A7 A7II III R RII RIII A7IV A7RIV A7S A300 A6000 A6500 A6400 A6300 A77II A100 A300 A450 A500 A580 A700 A850 A33 A55 A58 A65 A77 A99 RX100 II III IV by Brian Healy

I purchased this to try my hand at astrophotography on a recent trip to Utah. It was my first time attempting to shoot the stars at night. This shutter release worked flawlessly! I didn't have to make any adjustments (changing channels). It was so easy to use. Like I always recommend with any device, READ THE MANUAL cover to cover first and you will get maximum enjoyment from your new device. I'm extremely happy with how it performed and I'm eagerly looking forward to using it soon for some night shoots in Hawaii.
