With only 302 operating hours, your 2016 Arri Alexa SXT EV is an absolute gem. ARRI ALEV III sensors are legendary for their longevity, and because your sensor is barely broken in, it can deliver that timeless "Hollywood" cinematic look for years to come.
While the SXT EV is a heavier, "classic" studio-profile camera—making it less ideal for solo run-and-gun indie shoots compared to the Alexa Mini—it is still highly prized for music videos, narrative shorts, commercial studio work, and indie features trying to achieve a filmic look on a budget.
