Pretty dang close! There's more trickery applied to the M2P, which is why it also loses some sharpness & colour accuracy when RAW (DNG) images are analysed. The M2P is 1/2.3" & the Anafi is ever so slightly smaller at 1/2.4". Compared to my full frame camera (the big orange bit), it's tiny, here's a visual comparison of just how small they are.
Up until this afternoon, I actually thought that DJI had somehow managed to squeeze a sensor that was 1" across its diagonal into the M2P! I wonder how many others thought the same thing?
