ZEISS eXtended Data

[Kemalettin Sert]

ZEISS joined the /i Technology industry group and added their own extended data algorithms for distortion mapping and shading. /i Technology is an open standard developed by Cooke Optics.There are several parts to /i. The open-standard (public) core includes lens manufacturer, name, type, serial number, focus distance, T-stop, depth of field, and entrance pupil.
In addition to the core component of /i, there is also a proprietary (extended) area. It’s defined in a User Manual (tiny.cc/i-user).Obviously, there are certain things a manufacturer would not want to share with others and keep private between their lenses and their users. This is where a manufacturer can store lens characteristics like distortion maps, shading information and so on.And this is the area that ZEISS refers to as XD eXtended technology.ZEISS XD is frame-accurate and precise to 1 mm of focus and 1/10 of a T-Stop.

XD eXtended Data. ZEISS CP.3 lenses equipped with XD eXtended Data have four gold-plated /i Technology contacts at the 12 o’clock position in the PL mount and also a 4-pin Lemo connector protruding from the fixed barrel between the iris and focus rings.

Just wondering since all DSMC PL mounts have /i pins is it also gonna support XD lens data?

Yes, once RED updates the DSMC firmware and RCX Pro to manage the XD additional metadata!
