Fujinon MK 50-135mm T2.9 Compact Cine Zoom & Chrosziel Lens Motorization MK-Zoom Motor Bundle - E-Mount

This bundle includes the following items:

• Fujinon MK 50-135mm T2.9 Compact Cine Zoom Lens - E-Mount
• Chrosziel Lens Motorization MK-Zoom Motor

The Fujinon MK 50-135mm Cine Zoom Lens is ideal for indie filmmakers or the run-and-gun single shooter using a shoulder rig and a Sony E-Mount camera. The MK lenses are both fast and affordable by comparison to other cine lenses on the market. Image coverage is 28.5mm diagonal. In Super35 16:9 format that is 13.97mm x 24.84mm.

You can swap lenses on your rig with ease between this MK 50-135mm lens and the MK 18-55mm (sold separately). Focus, iris, and zoom gear rings are in the same position for this pair of lenses which launches the MK Lens family. In addition, no adjustments would be required when switching MK lenses if you are using both a follow focus and a mattebox due to same exterior dimensions (85mm outside and 82mm filter). With a common weight, you can also switch between the MK Lens family lenses without adjusting balance.

The E-mount short flange back helps deliver the lightweight size of these lenses. It also assisted Fujinon in providing a constant T2.9 aperture. 

Fujinon's MK Lenses produce high quality imagery and deliver a number of advantages. 

This lens is color matched to the Fujinon HK/ZK/XK series. 

Suppress Focus Shifts During Zoom

Unlike conventional DSLR lenses where the focal point shifts while zooming, the Fujinon MK lenses retain the focal point so you do not need to refocus when you shift the angle of view. MK Lenses suppress focus shifts by driving the front focus group and the zoom group independently. The lenses eliminate time lags normally found with electronic controls by suppressing both optically and mechanically. 

Zoom & Conquer Optical Axis Shifts

The MK Lens family reduces the optical shift which occurs in a DSLR lens while zooming. Fujinon adapted assembly technology from their other cine lens lines when designing the MK lenses. That means you gain the benefit of a zoom which stays composed on your subject.

Subdue Lens Breathing

DSLR lenses produce an unnatural change in the angle of view and magnification which creates lens breathing. MK lenses suppress lens breathing because of their internal focus system. The photo comparison Fujinon uses shows how a DSLR lens will seem to expand or breathe after you focus. Some bloggers explain this phenomenon by framing a doorway or a definable image so you can clearly see the change from maximum to minimum focus distance. 

Integrated Color Temperatures

Match your existing Fujinon Cine Lenses in the HK, XK, or ZK families with integrated color temperatures. Your post production team will thank you when you deliver A and B camera footage which matches color temperature.

Bokeh Effects

The 9-blade iris helps produce a beautiful bokeh. 

200° Focus Rotation Angle

Typical DSLR lenses provide only a 100° angle while the MK Lenses offer double that with 200°. With the MK lenses you can focus on images with shallow depth of field and capture with high accuracy. Zoom is 90° and Iris is 60°.

Features:

• Macro function
• T2.9 across zoom range
• Back focus adjustment
• 3 mechanical lens rings (focus, zoom, iris)
• 0.8M standardized gear pitch (all Fujinon Cine Lenses)
• Seamless iris for less noise and vibration
• Made in Japan

NOTE: MK lenses do not include the ability to transfer lens data.

The Chrosziel Lens Motorization MK-Zoom Motor is a compact zoom control motor specially designed for the Fujinon MK 18-55mm T2.9 (sold separately) and Fujinon MK 50-135mm T2.9 (included) zoom lenses, and Sony PXW-FS5 and FS7 cameras (not included).

NOTE: The MK-Zoom is also compatible with the user's PMW-F5/F55 when using the FZ adapter from Duclos Lenses (sold separately).

The unit attaches to the lens via two captive screws, and its drive gear mates precisely with the zoom gear ring of the lens. The integrated PCB with CPU instantaneously sets control commands (e.g., menu, user buttons) from a Sony or any other LANC-compatible control grip.

The form factor of the housing is sufficiently streamlined and compact, in addition to its out-of-the-way positioning on the side of the lens, to leave the unit installed permanently (eliminating the need to repeatedly add and remove it with different camera configurations). The housing design allows the user to freely actuate the focus ring without interference. A D-Tap cable supplies the necessary power from your camera's battery plate, while two LANC cables connect the MK-Zoom to the handgrip and camera.
