Canon Cine Lens CN-E 70-200mm T4.4 L IS KAS S

Features

High Level 4K Optical Performance

The 4K optical performance produces a significantly sharper image than 2K/HD. The various advanced design strategies used help to ensure over 4K resolution at picture center and a careful control of falloff of image sharpness at picture extremities.

The excellent contrast range associated with High Dynamic Range (HDR) imaging helps ensure both deep black reproduction and the excellent handling of scene specular highlights. HDR image capture significantly enhances both the contrast and the richness of colours in a scene, but it also poses a potential challenge in exacerbating the visibility of any lens chromatic aberrations. The Compact-Servo lenses’ optical design carefully anticipated this, incorporating advanced optical design strategies to help minimize such aberrations. 4K

Parfocal Operation – Precise Focus Through The Entire Zoom Range

Canon Compact-Servo lenses are parfocal in both manual and autofocus modes. The Compact-Servo lenses employ a special compensating lens group that moves to maintain precise focus while a separate lens group performs the zooming action. Maintaining focus while changing focal length allows the Compact-Servo lenses to be used in video production where zooming while recording is required.

Consistent Brightness Throughout The Entire Zoom Range

Canon Compact-Servo lenses maintain a wide aperture of T4.4 (F4.0) throughout their zoom range. This allows zooming while at maximum aperture without any dimming of the image.

Minimised Focus Breathing

Designed specifically for video production, Canon Compact-Servo lenses minimize focus breathing when adjusting focus, making them ideal for cinema production. Focus breathing is a change in magnification of the image when adjusting focus.

Continuous Iris Control

Canon’s Compact-Servo lenses can smoothly adjust between open and closed for precise exposure control and live in-shot changes. This can be useful to compensate for a change in exposure when moving between indoor and outdoor light levels within a shot. The 9-blade iris creates a rounded aperture so out-of-focus highlights appear circular. An odd number of iris blades increases the number of radial lines in a lens flare while simultaneously reducing the radial lines’ size, creating a less distracting flare. Compact-Servo lenses’ irises can also be completely closed, which is useful when adjusting black balance.

Image Stabilisation (IS)

Compact-Servo lenses offer three levels of Image Stabilization to allow for stable, smooth images. IS modes include the standard mode for handheld operation, a maximum mode for high-frequency movement such as vehicle vibration and a smooth mode intended for tripod-based operating. The IS function can also be switched off entirely to match user preferences.

Colour Consistency With Canon Cinema Lenses

Canon’s colour science has become highly refined over generations of lens designs, paying the closest attention to a pleasing skin tone reproduction. Compact-Servo lenses can be used interchangeably with other Canon Cinema lenses during the same production since both have the same warm, cine-look colour characteristics – making it easier to maintain consistent colour when multiple lenses are used.

Flange back adjustment

A flange back adjustment mechanism is built-in allowing you to adjust on site which helps to provide even greater optical performance among various cameras.

Focal length

The wide zoom range of the COMPACT-SERVO 18–80mm T4.4 EF and COMPACT-SERVO 70–200mm T4.4 EF is highly versatile, allowing the Compact-Servo lenses to be your main “go to” lenses. The generous 10mm overlap helps minimize the need to switch between lenses in the midst of a “fast-action” shoot. Go from wide angle to extreme telephoto with just two lenses. The 70–200mm T4.4 EF is also compatible with Canon’s EF 1.4x III and EF 2x III extenders.

Compact & lightweight design

Compact-Servo lenses borrow from Canon’s experience in EF lenses to deliver a compact and lightweight design. This allows lenses to be used in a wide range of shooting applications and environments. Both lenses are just 7.2 inches long, with the COMPACT-SERVO 18–80mm T4.4 EF weighing 2.65 lbs. and the COMPACT-SERVO 70–200mm T4.4 EF just 2.76 lbs.

Manual operating ease

Servo controls on Compact-Servo lenses can be disengaged for the focus, iris and zoom rings. All three rings are designed for smooth, fluid operation. In full manual mode, the barrel rings are direct controls for precise adjustment. The focal length can be set and with minimal focus breathing each Compact-Servo lens can function as a variable prime. The focus ring rotates 130 degrees for precise focus mark settings. The rings are geared to engage separate accessory controllers.

Servo zoom drive unit

The built-in servo drive controls zoom and can be powered through the lens mount or a separate port. It is compatible with Canon zoom and focus broadcast style controllers and an optional Zacuto® Z-CNYC Y-cable can be used to connect both zoom and focus controllers to each lens, allowing for simultaneous remote operation. For handheld use, the ZSG-C10 Zoom Servo Grip can be mounted directly to the servo drive of both Canon Compact-Servo lenses.

AF and AE capability-dual Pixel CMOS AF

Ultrasonic Motor (USM) drives provide fast and quiet autofocus. Select Canon EF-mount Cinema Cameras with Dual Pixel Autofocus are supported. Canon Electromagnetic Diaphragm (EDM) technology incorporates a motor directly to the lens iris for precise and smooth auto exposure response.

EF communication functions

Compact-Servo lenses are designed to work with select Canon EF-mount Cinema cameras. Because these devices are designed to function together, the complete kit adds enhanced functionality. Integrated autofocus, smooth image stabilization, connected control and metadata information, and lateral chromatic aberration correction are all included when using compatible Canon EF-mount Cinema cameras (EOS C700 / C300 Mark II / C100 Mark II).

Supports a wide range of optional accessories

Compact-Servo lenses are compatible with a variety of professional lens accessories. The front diameter is 84mm for mattebox mounting with a removable sunshade included. The COMPACT-SERVO 18–80mm T4.4 EF and the COMPACT-SERVO 70–200mm T4.4 EF both accept 77mm screw-in filters. An integrated support foot can be used to stabilize the lens on standard camera bracketry, and the zoom, focus and iris rings are geared for use with follow focus and remote motors. The optional ZSG-C10 Zoom Servo Grip mounts directly to either lens for handheld use and control of zoom, One-Shot AF and record trigger. The optional Zacuto® Z-CNYC Y-cable can be used to connect both Canon zoom and focus broadcast style controllers simultaneously for remote operation.
