Jim, if at all possible, can you PLEASE make the Red compatible with metadata from Arri/Ziess LDS lenses (Ultra Primes and Master Primes) as well as the Cooke /i metadata?
For those not aware of the situation, two issues are involved: the position of the contacts on the PL mount, and the incorporation of the LDS metadata into Red software.
CONTACTS
The position of the 4 contacts on the Red PL mount are in the 12:00 position (which works with Cooke lenses) instead of the 3:00 position on Arri lenses. This was first brought up in Greg Milneck’s post in November:
http://www.reduser.net/forum/showthread.php?t=5714
You can mount the Arri lens to align to the contacts, but the scales are then in the 12:00 position.
Arricam bodies have the contacts in two positions on the PL mount—12:00 and 3:00. This allows the scales to be read in either low mode or normal “AC” mode. It also allows you to mount an Arri LDS, Cooke /i S4 lens, or LDS Optimo, and use the metadata from any of the lenses.
It would be great if Red could do the same. That would give everyone the flexibility to use any intelligent lens set and get the benefits that these modern lenses offer for both production and effects/motion control work.
I understand that a lot of work went into making the current PL mount rock solid, but couldn’t you simply provide a second set of 4 holes at the 3:00 position on the PL mount, install contacts and the necessary wiring?
Looking at the current mount, it seems quite doable.
If that approach proves cost prohibitive for some reason, can the current PL mount be simply rotated 90 degrees so the contacts are in the 3:00 position? In that case, it seems all that would be needed is a longer wiring harness to the contacts. That would allow users or a local lens shop to rotate the PL mount. Doable? If not, can we order a camera with the PL mount oriented with data contacts in the 3:00 position?
Of course that approach would force users to chose one type of intelligent lens system over the other—not great for anyone in the rental market, or users who may want different lenses for different projects, or only have access to certain lenses at any one given time from local rental houses.
SOFTWARE
On the software side of things, it’s my understanding that the Arri LDS system and Cooke /I data systems ARE compatible.
You can use a Cooke /i data lens on an Arri body and capture the metadata, just like an Arri/Ziess or Angenieux LDS lens.
In discussions last week with two Arri representatives as well as the Cooke dealer in the US (ZGC) both camps have stated that the two systems are fully compatible from software perspective. In fact, Arri told me they invented the system, shared it with Cooke and Angenieux, that it is not proprietary, and in fact, have given the protocols to Red. Is that true?
If so, that doesn’t square with Jarred’s responses on Greg’s LDS thread in December:
“the connections are both the same, its just different data.”
“LDS is (currently) a closed proprietary system, where the /i system is an open standard so other companies can adopt it like (like Red), which is how we put it on our zooms and on our camera. It’s the same signals and the same contacts, just different info moving back and forth.”
We have no problem working with Arri, or no problem working to get LDS integrated, but its not that simple.. its one thing to get lenses to talk to to an Arri body because Arri still controls the data... its another thing for Arri to give us the keys to the protocol to implement into our camera. And the ball isnt just in Arri's court , we need to allocate the resources for development and integration.”
“The first protocol we will support is the /i system.”
So what’s the current status? Did Arri recently provide the LDS software protocol “keys” to Red? If so, that would lead me to believe that Red DOES intend to make LDS compatibility a reality—which would be awesome.
I totally understand that Red is advertised as an /i system, but I hope Red will provide a solution for the contacts and integrate the Arri data into the Red software stack so Red users have more flexibility in how they use their cameras.
The analogies to the computer industry certainly seem to apply here. Let’s keep Red the innovative hardware/software “open system” that opens opportunities for everyone, levels the playing field and benefits a loyal and passionate community of users. Opening up Red’s lens mount and software to embrace both Cooke i/ and Arri LDS would be a big step in that direction.
You’ve done an awesome job getting this kick-ass camera to market, and I can’t wait to get mine. I just want to be able to take full advantage of it, and hope you’ll make this capability available.
Thanks for your thoughtful consideration,
Mark
