Intelligent Lens Mount/Intermediate Lens Mount

[AIO Films]

If this has been answered recently, I apologize as I don't check all the postings on a daily basis.

A while back, for obvious creative and economic reasons, posters were talking about mixing different lenses (with different mount types) in a shoot. We were wondering how easy/fast/safe it would be to change the lens mount on the RED ONE body.

Someone came up with a brilliant idea of having an intermediate mount that would easily click onto the camera body on one side and connect to the lens on the other. Red (or a third party) can provide mounts for different brands of lens manufacturers (PL, Nikon, Leica M, Leica R, Contax/Yashica, OCT-19...what have you) and a common interface to the camera body.

Are there any updates/answers to both questions above?

Please enlighten us so that we can plan our lens strategy ahead.

I'll only be using Nikon primes on my RED, so I'll be changing lenses A LOT. I was wondering also if the sensor is completely exposed when changing lenses or is there a glass IR filter or something to protect it (I know that there's no internal filter wheel)?

[Steve Gibby]

There were previous threads on DVX User RED forum asking that, but to my knowledge it hasn't been defined/finalized by RED. Obviously dust getting to exposed CMOS sersors is a continual problem with DSLRs. 2/3" cameras have a glass plate behind the lens mount, so dust to the sensors are not a problem. My gut feeling is that there will not be a glass plate behind the lens mount on RED One, because of the varying depth of the multiple mounts the camera will use, so care in where/when you change lenses should be the same as with a DSLR. I'm sure RED will have recommendations for cleaning dust from the sensor on RED One.

Hi Gibby,

From what I gather there is a window. It's the combo infrared/ anti alaising filter.

Yes, there will be an optical low-pass filter over the sensor itself. That said, treat changing lenses with the respect it deserves. Compare it to a film camera or a DSLR and bump it up a notch [no mirror to protect the gate]. Keep a can of compressed air handy. :)

I can't count the number of times I've seen a new AC yell a craft-services-breath "good gate!" directly into the exposed gate and mirror. Obviously there won't be gate checks here... but just imagine what that would do to a sensor.

Oh yeah, I was well aware of the OLPF, which RED One would have to use, but my post was targeted at the lack of a clear glass plate right behind the lens mount, like the ones used on all B4 2/3" cameras. This is different from an OLPF, IR, or AA filter. This glass plate funtions as a protecting barrier to keep foreign matter from entering the inside of the camera when you change lenses. What I meant in my post, and perhaps it wasn't explained well enough, is that a protective glass plate, like that on B4 2/3" mounting cameras, will probably not be possible on RED One, most likely because of the varying depths of lens mounts that RED One will use.

What is a craft services breath? lol

Taking the Jim's own words, it would/will be easy:

«Very easy. The Trick is to have the base to intermediate mount distance set at the factory and leave enough room for all possible mounts. More details pretty soon.

But some film guys (from the cinematography side) are saying that won't be.

You don't want to know... and you really don't want it in your camera.

This is a bad idea, you can easily damage a sensor by hitting it with some of the super cold "juice" that can sometimes find it's way into the tube of those cans. Much better to use a hand blower or better yet a specifically designed sensor cleaning brush.

I use the Vsable Dust Arctic Butterfly.

I dunno, Evin. I find this a much less expensive option for craft services breath myself. Compressed air actually works quite well as well.

:D

Thanks for the info. I wish something more concrete and favorable to our request will be announced soon.
