I want a Fuji XH2S for the sensor, resolution, open-gate, ProRes, film simulations etc.
But as a working pro, already invested in Sony ecosystem plus an FS7.. the FX30 makes better sense.
FX30 does have some nice features like Cine EI, LUT import & TC. Nice ergonomics, top handle with XLRs. Active cooling.
And yes, rock-solid AF. But I'd also adapt glass and use a speed booster.
It's just not very exciting, at all really. Completely utilitarian like most Sony cams. No real innovative features. A "new" old sensor. Sony aren't breaking barriers like Fuji, they are simply diluting their cine line. Making it more accessible. Most accessible ever, really. And that'll probably be enough for them to make bank. They also have bunch of A7III/A6xxx users that will upgrade to it, as FX3/A7S3 were above their budget. And FX3/A7S3/FX6/FS7 users that will add one as B-cam.
Those are the main purchasing scenarios imo.
