Best praise vs top criticism for Sony FX30

Best Praise

โ€œCould you share some more info on what he is wanting to shoot, is it his first time operating a camera ? Is he studying film ? Is he starting a business? If he is just starting out, just get him a zve10 sigma prime (30mm 1.4) and a gimbal. If he is purely shooting video. The FX30 is a great camera. (But higher price bracket).โ€
