Just thinking here.
Everyone likes buzzwords, right?. So wouldn't it be cool to change some of the Crop_rec presets' names for the 5D3? Like 3x Crop mode is as close to Super 16 as it gets. (12,35x7,5) / (12,4x7) 36x24:3 = 12x8.
3.5k mode equals 1.65 crop. 35 mm Film is about 1.7'ish crop not to be confused with Super 35's 1.5 crop which ML also can achieve, but in not so favorable recording times.
With all the talk I see in youtube videos about emulating film or sticking to "true" cinema etc. I think adding some buzzwords could boost the popularity of ML further.
'Super 16 Mode' and '35 mm Film'?
I've been shooting a lot with a ultra wide vintage lens in "super 16" mode and the look is just fantastic, kinda feels like a little camera within the camera

Anyways, just an idea I've been contemplating.
