Prime Circle XE System Continued

The Prime Circle XE lenses are world class optics (Carl Zeiss) in a high-end shape and cine-style ergonomics with dedicated XE and XE-Z wireless controllers and a FZ intelligent mount (a micro 4/3 follows shortly).

Large focus scales (cine-style focus classic direction) on both sides of lens barrel for precise focus-pullers work, and 95mm front mount across all the lenses sizes.

The optics offer magic cinematic feeling engineered by the most prestigious optical manufacturer in the world.

Based on the popular EF Mount the Prime Circle XE can be mounted on every EF Mount camera, or several different cameras with FZ Mount or micro 4/3 with the XE System intelligent mounts. Lenses aperture can be controlled wirelessly directly from the d.o.p. chair in front of the control monitor.

Modern EF Mount cameras can control directly the Prime Circle XE lenses aperture, or with the wireless XE Controller it's possible to control image exposure far away from the camera.

The XE System intelligent mount (adapter) offers the option to reach the same freedom with Sony FZ, Panasonic, Blackmagic or other cameras.

The XE Controller is dedicated to Canon EOS cameras and the XE-Z Controller is dedicated to the XE System intelligent mounts, offering a wide production choice across several cameras mounts.

The XE Controller has an integrated rechargeable battery for up to 18 hours of continuos shooting, and offers LiveView On/Off, Focus function recalling wide open aperture for precise focus check, also start/stop Rec is available.

The O-Led display can be checked in total sunlight or in total darkness!

The XE/XE-Z Controllers are really compact (pocket size)and heavy-duty for rough abuse on movie productions.

The XE System Controllers features the exlcusive K-Link protocol for future applications of “intelligent” accessories under development right now!

UPDATE: Got this note from Zeiss…

Please be aware, we do not honor the warranty on our ZE or ZF2 lenses modified by Prime Circle. This means we will not service the lenses or provide spare parts. Carl Zeiss does not supply them with lenses, nor do we endorse this modification. The buyer should be aware of these facts.
