I spent 8 years shooting with a 30-pound TK-76 in the late '70s, early '80s. Ruined my back/neck with herniated discs.
Nevertheless, for me it's always about ergonomics. The trend that began in the '90s holding a camera out in front of you was a deal (back) breaker for me.
A video camera, in my opinion. should be positioned on the shoulder.
That's why this is a sensible and good camera! Long live Arri.
