don lee Posted July 10, 2007 Share Posted July 10, 2007 I have always figured my Beta sp camera to have an effective ASA of @250 (at zero gain). Has anyone calculated the ASA for the Sony Z-1 or the Canon HD DV cams? It feels like ASA 250 but I would appreciate the formula...thanks Link to comment Share on other sites More sharing options...

This is from shooting a properly exposed gray card, and comparing a light meter reading to the camera internal exposure meter. I've heard this is very similar with most other DV/HDV Camera, at least the Canon ones. Link to comment Share on other sites More sharing options...

don lee Posted July 10, 2007 Author Share Posted July 10, 2007 Thanks for the replies...i know the older cameras were rated at 200o lux at f8, and then newer ones like the Sony 600 were bumped up to 2000 lux at f.11 but i never knew how to translate that into an ASA....
