The Fujinon MKX50-135mm T2.9 Lens in X-Mount is a lightweight cine-style zoom lens for X-mount cameras with a Super 35mm-sized sensor. The electrical contacts within the lens mounts allows communication with X-series cameras. 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 or 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 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 cameras with a Fuji X-mount, so it has a short flange focal distance, but the lens allows flange focal distance adjustment so you can fine-tune it to the camera you are using the lens on.

The electical contacts within the lens mount enables communication with X-series cameras, which allows for correction of distortion and color/brightness shading to prevent vignetting. This communication also enables you to achieve a variety of color expressions when using Film Simulation modes.

Q: 2. which lens would you recommend fungi 14mm or XF 10-24mm?

A: Wow, I could bore you with what I shoot and why; indicating that I am either a photographer or an idiot with money. I Shoot the prime. I shoot only primes with only one exception and this is not it. PhaseOne/IQ260, Arca Swiss, Fuji...it doesn't matter. if you want the best from a lens...you by prime. HOWEVER: if your purpose says you MUST have this range for some unknown reason and you cannot live without that range AND your budget says NO to primes...then, of course, you shoot the 10-24.
