Who Still Uses This Pioneer

Some filmmakers still use this old workhorse for its unique look. Crews pull it out for art films, old-time stories, and jobs where that warm look beats sharp edges. Some top directors won’t shoot with anything else even with all the new gear. They say it has a look that the new stuff can’t copy.

Bottom Line

The ALEXA HD looks basic now, but it kicked off a revolution. It showed that suitable sensors and color matter more than just counting pixels. This box changed filmmaking forever by proving that digital could work, whereas only film had succeeded. Though old now, it still makes pretty pictures and holds a special spot in movie history.
