This aperture series from f/2.8 to f/11 with the Canon RF 24-70mm f/2.8L IS USM at 56mm shows a pronounced forward focus shift which has major implications for total image sharpness unless it is compensated-for. Results here were confirmed with other series over the zoom range—consistently strong focus shift.
