February 14, 20196 yr Hi All: Forgive this question if is a repeat. As per the Mark Galer video series, "When capturing images in AF-C, alpha mirrorless cameras will focus at the aperture selected." What I'm seeing with my a9 with 24-105G OSS is in AF-C the aperture breaths open to acquire focus at small stops, f10-f22, albeit not so much as AF-S. This creates noise. I'm a unit stills photographer and this is an issue. Also, I hear a little noise sometimes when I depress and hold the shutter button down for multiple exposures. Audio Signals are turned completely off, set to electronic shutter, and Live View Display settings effect is on. In the below video I am at f22, first pass is with AF-S, second is with AF-C. Any thoughts would be great. This forum is fantastic! Thank you. AF-S then AF-C F22.mov
