Exploring ZEISS eXtended Data With CP.3 Lenses – Perfect for VFX

By Olaf von Voss

eXtended Data

At IBC 2017 we caught up with Sundeep Reddy from ZEISS to discuss the now-ready eXtended Data feature of the new CP.3 XD lenses. So what is eXtended Data, anyway?

We caught first sight of the new CP.3 line of prime lenses at this years NAB show, more precicely at a special event hosted by ZEISS. Aside the freshly developed CP.3 lenses there was more to discover: A feature called eXtended Data which would be part of a twin-line of CP.3 lenses, called CP.3 XD. These are the same lenses but add a inconspicuous Lemo connector to the barrel. In comes the magic. Aside of its premium of around $1400 per lens this tiny connector is capable of giving your VXF artist a sense of pleasure.

ZEISS eXtended Data

Basically, the XD labeled versions of the CP.3 line of ZEISS lenses can provide you (and your DIT) with the following: A calibrated internal encoder gathers shading & distortion data of that exact lens. The provided data flows through the Lemo output of the lens through a Master Lockit device by Ambient and then further on to your DIT station via wi-fi. Pomfort’s Silverstack or Livegrade Pro are there, awaiting to process the data in real time.

The whole process is based on Cooke’s signature /i data system but this time around with the famous ZEISS , eh.. look.

As a result, you’ll get a so-called ZLCF, or ZEISS lens correction file which is not limited to the already mentioned Pomfort products. DaVinci Resolve is also capable of processing these. The distortion and shading data can then be used to speed up your Post and VFX workflow. Stiching together shots will be far more easy when all the lenses used are already matched up perfectly, for example.
