When shooting 16:9 on the Alexa what is the ratio, as far as lense size, between 35mm and the Alexa? I'm shooting a spot this week on the Alexa and we need to find out some very specific lense lengths that we need. Production can't afford a set of lenses for the tech scout so I'll have to rely on my Mark V viewfinder. Wondering what the difference will be between the two formats, if any. I know they are similar, but need to know if there is any difference at all. Thanks everyone.

The recorded sensor width is 23.76mm, more or less the same as Super-35, which is 24mm wide. Not sure your directors finder has 16x9 Super-35 framelines though but it's basically the same as 3-perf 35mm.
