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.

What is the 35mm equivalent focal length of this ...
What is the 35mm equivalent focal length of this lens. Is it 36-110mm or something else?
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
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
