Together with IBIS it allows to shoot 1/4th of a second at 105mm with quite consistently sharp results. - RF has way faster AF. - both IS and AF are much quieter with RF. - EF feels more rigid thanks to its metal body. - EF suffers from the barrel wobble at 24mm. No impact on IQ, it is just the feel.
Usable Aperture Range: I often just set it either at F4 or F8 and have no issues. Low light performance on the Canon R6 is actually quite nice, you can probably expect this lens (in this setup) to act more like a F2.8 lens on older DLSRs when low light performance is considered. Bodies Used On: Canon R6, Canon R5. Source: MPB faMDs.
