CANON Lenses Stand out in 3D!

3D is the broadcast trend of the moment. And Canon lenses have unique advantages for 3D production.

3D requires two lenses, however rigged. And it is vital that the 2 lenses must be almost 100% synchronized.

Thus, the lens must have two features: highly accurate servo systems based on rotary encoders for zoom, iris and focus, and also a function to adjust the end position.

Canon is a pioneer in the development of Digital Drive units for its portable lenses. Its control systems for 3-D lens-camera-pairs capitalizes on the precision of these Digital Drive units, allowing one zoom controller and one focus controller simultaneously to operate both lenses. This ergonomic Digital Drive unit incorporates Canon-developed, ultra-compact rotary encoders capable of 0.1um position detection. They employ Canon's unique Micro Roofmirror Array (MRA) technology to produce 16-bit resolution of the positions of the zoom, iris, and focus controls.

These enable camera operators to program digitally precise and repeatable settings into their lenses: for speed, focus and iris, as well as zoom positions.

In addition, 3D Adjustment Lens Software makes stereoscopic tracking (lens zoom and focus) even more precise: and allows differential offsets to be made - through the Digital Drive unit's display - to compensate for minor zoom and focus tracking differences between any two lens pairs.

Most Canon HD portable standard lenses have rotary encoders built in, with the display on the drive unit. This enables exact adjustment of the end stops, speed and so on for zoom, focus and iris.

Therefore…no special lens is required for 3D production with Canon.
