I just got the 75mm f/1.8 and it has an interesting behaviour when shooting in PSAM modes. Because this lens has very large aperture blades, you can hear the blades quite easily. This issue is that it make this noise in all the PASM modes, but not in video mode. Also, not if I choose the AEL button (or half press the shutter). It seems it adjust the live view of the screen and makes the sound when moving the camera around. On my E-M1 ii, it doesn't do this. Anyone know why or how to fix this on my new E-P7? I' rather certain other Olympus cameras must exhibit similar behaviours.

Never mind. I found the problem. I set my camera's "flicker reduction" to "50hrz". Apparently, anything other than "auto" messes with the cameras ability to no do this. I confirmed this on the E-M1 ii. Set the flicker reduction to "50hrz" and it exhibits the exact same behaviour. Still, if this happens to you, it's good info to know.
