Alpha 9 III

Others have explained why this happened. I just wanted to add: If you ever get to a point, where you need silent shooting / electronic shutter in sports photography, look for cameras with “stacked” sensors. Like the Sony A9, A9II, A9III and the A1 cameras. They have much faster readout, in the singl

Sony a7v sensor readout is about 62ms and my canon r7 is about 35ms. Rolling shutter shows up about 10%of my shots, so yeah it’s got to be from the read speed. Go mechanical or buy a faster readout camera. Sony a9iii for 0 second read out but anything around 10ms is probably good for this scenario.
