Fujinon MK18-55mm T2.9 Overview

The Fujinon MK18-55mm T2.9 Lens is a lightweight cine-style zoom lens for MFT mount cameras with a Super 35mm-sized sensor. It features a mechanical design with three independent lens control rings: focus, iris, and zoom. Each ring incorporates a cine-style gear with a 0.8 MOD for interfacing with standard cine-style lens accessories. The focus ring features approximately 200° of rotation, which provides room for precise focus pulls, and the iris is clickless, enabling smooth iris pulls. The lens also incorporates a macro mode for close focusing capabilities.

The lens is color matched to other Fujinon lenses such as the HK, ZK, and XK series, which enables smooth intercutting between lenses. The 85mm front thread enables use with many cine-style matte boxes via use of optional step-up rings (rings not included). The lens weighs only 2.16 pounds, which is fairly light for a cinema zoom that holds focus and aperture throughout the focal length range. It is designed for camera's with an MFT mount, so it has a short flange focal distance, but the lens allows for flange focal distance adjustment so you can fine tune it to the camera you are using the lens on.

T2.9 to T22 aperture with nine iris blades for attractive bokeh
The 28.5mm diameter image circle covers the 3-perf Super 35 format with a 16:9 aspect ratio
Industry standard 0.8 film pitch gears for focus, zoom, and iris control
The gear rings positions for focus, zoom, and iris are located at the same position on lenses in the MK series, making switching between the zooms quick as you don't have to adjust the position of lens accessories
Lenses in the MK series have the same weight and length so there is no need to rebalance your camera when you change from one lens to the other
200° focus barrel rotation
No shims are required to adjust the flange focal distance as this lens has a built-in adjustment mechanism
Macro focus function available

What is the 35mm equivalent focal length of this lens. Is it 36-110mm or something else?
Asked by: W. Bill
This will all depend on the crop factor of the camera being used. If you are using it with a camera like the Pocket Cinema Camera 4K which has a 1.9x crop the equivalent will be 34 - 105mm.

Do you need to adjust back focus at all to get the lens perfect parafocal throughout the zoom? Shims etc
Asked by: Stone
When working with different cameras, even if the mounts are the same, it is always safe to test your back focus before your shoot to ensure the lens focus is correct. No shims are required to adjust the flange focal distance as this lens has a built-in adjustment mechanism

question

This wont come out for a C300 mark II right?
Asked by: walter
You are correct. This lens is made for the short flange depth of the mirrorless E mount standard and is thus incompatible with the longer flange depth of the mirrored camera EF mount standard. The lens, even if you were to mount it, would therefore not be able to focus on the C300 sensor. It would be too close and focus it's picture somewhere behind the sensor's image plane. The nice thing for E mount users is how this lens is smaller, lighter and speaking to it's quality and features, relatively inexpensive.

The listing says that it's MFT, just wanting to confirm that it will work with the Blackmagic Studio Camera 4K? I'm also curious about recommended focus/zoom/iris controls for a live broadcast setup?
Asked by: Joshua
The BMD Studio Camera 4K does have an MFT mount. These lenses will work with that camera. However they are manual cinema lenses. For Focus, Zoom and Iris Control you would need to look at a system like the Tilta Nucleus-M and add a 3rd motor to it.
