We put the B4 mount on the Red One Lens mount today and shot some quick tests... we Used a Fuiji HD B4 zoom and Im glad to announce we have a very, very healthy optical margin around the 2k windowed frame...

all you who plan on using your B4 lenses.. today was a good day for you.
 
Woo hoo! Wow! This just gets better and better! First the Nikon F-mount! Now a B4 mount! This IS going to be the most versatile image-making machine on the planet!

That is great news (2k windowed frame... ). As a matter of fact, I am currently looking at a few Fuji HD zoom lenses. Jarred, what model were you guys using and can you elaborate further on your impressions? First, I have things together to purchase the RED lenses and now this? Great news all around.

Cheers

great news. thanks jarred. out of curiosity..was the RS232 connector enabled for use of the zoom servo for the lens?

no lens controls.. just manual.
 
Will RED one equip the 12 pin lens connector for those HD TV lenses ?
Will the EVF display last secs recording of picture while pressing the RET switch on those HDTV lenses ?

for the B4 test - did you use some kind of adaptor or glass behind the HD B4 lens ( for it to focus light(rgb) on same image plane ) ? or does the RED B4 lens mount have some kind of glass behind it ?
 
here is one of the frames.. you can see the roll off from the adapter. Its still amazing to me how large the Mysterium sensor actually is.. I still do a double take when i drop 1080 or 2k frames inside the massive 4k active area.

Thanks Jarred. Since that optical margin is so "healthy" around the 2k frame, is the a multiplication factor for the lens' focal length?
 
Ok that does it I am going back to the gym...
Widescreen test chart dummy that I am.
Hey Jarred is this the full frame Mysterium?
Meaning it is more like 5k ?

But Emanuel, what about the football @120fps?

Good one, Andrew! I believe these RED pioneers where some of us are included...are rocking as well. With the lesson well studied.

1080p RGB even if not @120fps but up to 60fps will go rock too. 400% from 2K to 4K is a lot. Especially if and when our target may have the big screen or the future proof as its core mission. On the other hand, we'll have the benefits of downsampling [LINK].

:)
 
E., I read somewhere were Rob said we could go 2K (windowed?) 120fps using the RAW port to RED RAID. If I am wrong please correct me. This would be great for sports, etc.
 
Yup but taking this:
http://red.com/formatoptions.htm

EDIT -- 2K windowed is not 2K scaled, so there aren't the benefits of downsampling. Only less than a quarter of the full S35mm sensor or 35mm/4K capability. Working as a 16mm camera. Still, you'll need for S16/16mm or B4 mount lenses if you want to go wider. The magnification factor will compromise the 35mm glass use, unless for tele purposes (@FOV level). But without changes @DOF. Although the 2K windowed DOF will surely be different than from the 35mm/4K format.

Not my ballpark, anyway.

Sports can go well. But not so wider or cinematic (4K compared). Even with the proper S16/16mm or B4 mount dedicated glass, wider yes. Apart the 35mm shallower DOF style. And nice for ENG/EFP and one-operator-show style 'cause the deep DOF properties. However, even for sports and following the sport photography, it doesn't seem that we can assume a deep perspective preference -- targeting its core point-of-view. Given by the shallow DOF and not for its opposite. The imaging craft (it doesn't matter where) is always a balance from all you can get. (from) More. Not less.
