These look really good. Looking forward to the comparison video's of the nikon zr, canon r6iii, panadonic s1ii and I guess still the sony a7siii.
(Would get the s1ii for the ibis, nikon zr for the monitor and IQ(but fear the datarates), hope the r6iii has similar IQ as the zr and good ibis, and the a7siii/fx3 is still somewhat industry standard which has benefits like lots of good luts available). + I still own a bunch of EF glass which really works well on panasonic. (Adapting it to sony kinda sucked back in the day, nikon not sure, canon should be pretty flawless I guess)
