FZ80 does BIF
The FZ80 is quite capable of capturing birds in flight. I set S Mode on the Mode Dial, shutter speed 1/1000 is light permits, AF-C, Burst-M, for 6 fps with AF, AE and live view on each frame. The main limitation is user skill and experience. Just keeping birds in flight in the viewfinder is a challenge.
With RAW + JPG capture I get 14 frames before the rate slows.
With JPG only capture the camera will shoot at 6 fps until the card fills.
The camera continues to work while writing to the buffer.
