Yeah, the zhiyun smooth q is only for phones... Altho it can handle a gopro as well.
The zhiyun crane m is around 350 and it can handle cameras like sony a6500.
I would recommend you to save up for a gimbal, not a steadicam, because that is so 2008 :D
And a agimbal will give you way more than a steadicam.
Altho it depends on what type of shots you want... A steadicam can give you this natural looking flowy motion. But gimbal is more in place. If you know what I mean.
I myself prefer a gimbal. :)
