i am not comparing i am just saying it lacks stab, that is my opinion
of course you don't need it when using tripod, using slider, hmm it depends on the build quality, dolly same story, there are many that shake the camera
and why comparing with red or expensive products ?
comparing a 1500$ camera with some 15k$ others is a nonsense as the equipment are not the same and the way you work with it and the team around are not the same.
for gimballs many prefer to use them with stabilized lenses or body in order to avoid jittering.
this camera is the kind you want to use handheld sometimes, expecialy with the great af, having a stabilized lense would be such a great thing
