Using lens to adjust aperture
Using lens to adjust aperture Apologies for what is probably a silly question. I have recently acquired an Olympus EM-1 MKIII. I am used to film photography. When I first began trying out the camera, I was able to adjust the aperture by rotating the lens. I’m suddenly not able to do this. I must have fiddled with something, but I don’t know what. Does anyone have any idea...
