S35 Scarlet vs. S35 Red Frame Size vs. real S35?

[JLeonzio]

OK. I'm a little confused here. According to my ASC manual and just about every other source I can find, the true size of a S35 frame is 24.89 x 18.66mm. The RED One is slightly more narrow at 24.4mm x 13.7mm and the Scarlet S35 is now considerably wider at 30 x 15mm.

Two questions:

1. So why are we calling this S35?

2. Will cine lenses even cover the Scarlet S35 frame, considering they were designed to cover only the traditional S35 frame?

Your thoughts...

My understanding was that the larger sensor provides viewable edges around your recorded frame, to assist with monitoring and composition.

Yes, because currently when you record 4K (4096) with the RED, you aren't using the full Super-35 width of the sensor, the rest is used for lookaround monitoring (very useful) -- it's more like Academy width (22mm) in terms of image area. So if you want 4096 to be 24mm wide, then you'd want the sensor to be even larger to provide more lookaround viewing, at least 26mm wide.
