  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

B4 Mount

What about the comparison between the windowed Mysterium/Bayer and a 3-CCD camera in terms of image quality? If the RedOne gives me more dynamic range (11 stops has been discussed) and offers me a RAW color space for grading I feel pretty good about the RedOne's ability to win that one easily.

Well, the 3CCD cameras you're probably referring to will have a lower resolution, more limited color space, higher compression, significant chroma subsampling, narrower dynamic range and no noteworthy upgradability. And they'll probably cost more.

So... hooray!

Using a B4 lens on RED

Reference - http://red.com/images/photo_zoom/redone_14.jpg

Closest to lens side of the camera - three circular connectors

Upper - EVF interface
Middle - LCD interface
Lower - B4 lens interface.

This interface can provide 12V power via the industry standard 12 pin connector to a 2/3" broadcast power zoom lens.
 
That's awesome...thanks for that added info on the taps Stuart, and a giant thanks to RED for including 12v auxiliary power in RED One! It goes a long way toward enabling the flexibility and utility of RED One.

Thanks...

Hey Stewart - thanks for you info -
will it be a Canon or Fuji pin?
my vote is Canon
thanks again

I am probably being thick-headed late at night here, but I don't understand the post by Reedpi. We have used Fujinon (primarily), Canon and Angenieux ENG lenses on our Cameras (Sony F900R and Sony HDC1500) and they all fit the same lens connector on the camera body, which I think of as the Sony lens connector (not Fuji or Canon).

Zoom and Focus controllers are a completely different matter.
 
Power to HD and SD B4 2/3" lenses is definitely via an industry standard 12 pin connector, as Stuart mentioned. Each lens manufacturer has their own multi-pin connectors for zoom and focus controllers.
 
B4 interfaces

B4 interfaces

Multipin control interface to remote transceiver like on a robotic camera or jib head should allow for focus pulling and more on a B4 lens. Might be a nice option when shooting wide open even with the more liberal apparent DoF in the windowed modes (2k or 1080) that the B4 implementation supports.

In a perfect world "Cine style" work would always be done on a S35 or 35 lens with a proper follow focus rig. However, due to the ubiquity, convenience and relative affordability of B4 glass - we will be asked to shoot cine style on B4 and it would be handy if there was a way to take advantage of the existing interface. Perhaps there really is no substitute for a proper follow focus rig or an operator who can rack for themselves but I can't help but wonder.

Thanks Gibby. I was fairly certain that was the case. I assumed "industry standard" meant Sony did it first and then everyone else went along, sort of like the B4 mount itself and V-mount batteries and many other things.
 
Great news Red Team!

This is an important step to making RED a versatile tool. I'm very glad this option was not overlooked. Especially considering how much reality TV gets shot these days.
