In response to a reader’s request, I’ve recorded the two camera’s shutter noise. First set of noises is the GF1, second is the E-P1. Seems the E-P1 has a higher framerate. The GF1 is slightly louder and i find the noise more intrusive. I’d add the sound of a DSLR on as well but … I don’t have one anymore. This is a website about small cameras after all!
