So you actually cannot generalize this end result. For one, primarily based on testing with only one focal size you may’t extrapolate into how every system fares with for instance a 24 and a 100 mm lens. It additionally may be utilized to shopper grade lenses just like the Canon RF 50 mm 1.8 STM, as these constrain the picture sensor movement additional.
I’d additionally count on Canon to additional their benefit in terms of combining lens IS with IBIS, because the bigger mount provides them extra freedom to maneuver the sensor round. So these outcomes additionally do not apply to that.
However for the particular case of the 50 mm 1.2 lens, this appears to be like like a pleasant check and as that may be a lens that does profit from stabilization, it’s good to see that Canon demonstrates a hanging absence of Doom as soon as extra.
