Hi Jim, Jarred and Stewart
PLEASE don't make a proprietary RED lens mount. Leave the full frame 35mm lens market to Canon, Nikon, Zeiss, Leica etc. There's many great options and the other makers have a 50 year head start and 1000's of products available new and used at attractive prices. I'm sure you could do it well, there just is no need for it.
Concentrate instead on delivering the Red primes asap, more of the 18-85 zooms, a longer 25-250 brother to the 18-85 of similar build and quality. While you are at it how about a PL rehouse of that rocking Tokina 11-16 f2.8 ? or something better in that range.
Modern PL mount cine grade optics are what we need to shoot with on the Epic, don't jump into the consumer 35mm lens format.
Thanks for listening,
