Fujifilm FUJINON MKX 50 135mm T2 9 Análisis | 54 Datos comparados

Overview and Technical Capabilities The FUJINON MK 50-135mm T/2.9 is a fully manual, dedicated cinema zoom lens designed specifically for filmmakers using Sony E-mount cameras, such as the FS7, FS5, and a6500. Engineered for documentary-style shooters, the lens covers a versatile telephoto focal range that seamlessly pairs with its wider sister lens, the MK 18-55mm. It features a constant maximum aperture of T/2.9 across the entire zoom spectrum, delivering sharp images even when wide open, alongside a par focal design that retains focus while zooming. Structurally, it features industry-standard 0.8 pitch gears on the focus, zoom, and iris rings, a macro mode, and a physical back-focus adjustment built directly onto the barrel. To optimize production workflow, both lenses in the MK series share identical physical weights, exterior dimensions, and front diameters, eliminating the need to rebalance a drone, gimbal, or camera rig during swaps. Pros, Cons, and Performance The primary benefits of this cine zoom lie in its lightweight, compact design, affordable pricing for a professional cinema optic, minimal chromatic aberration, and lack of visual focus breathing. However, the review...

The Fujinon MK50-135mm T2.9 is a high-performance, affordable cinema zoom lens designed for Super 35/APS-C cameras, offering true parfocal performance, minimal focus breathing, and 0.8 MOD geared rings for under $4,000. It brings premium optics and a lightweight build inherited from Fujifilm’s high-end Cabrio line, making it a viable, budget-friendly option for cinematographers. However, the lens is limited by its strict Super 35 coverage, resulting in vignetting on full-frame sensors, and currently lacks native mounts beyond Sony E at launch. Additionally, the under-1kg weight is achieved through materials that sacrifice the rugged, weather-sealed, and electronic-linked construction found in more expensive alternatives.

The No Film School field test of the Fujifilm MK 50-135mm T2.9 highlights the cine lens's lightweight design, consistent 85mm front diameter, and perfectly matched gear positions for seamless swaps with the 18-55mm lens. It is praised for its true parfocal performance, 200-degree focus throw, and an image quality that balances sharpness with organic softness. Conversely, the review notes the lens is limited strictly to Super 35/APS-C coverage, requiring workarounds for full-frame sensors, and features a minimal, non-drastic macro mode. Additionally, the fully mechanical design lacks electronic metadata communication with the camera body.

The Fujifilm Fujinon MKX 50-135mm T2.9 is a fully manual, Super 35mm/APS-C cinema zoom lens featuring a constant T2.9 speed and 0.8M gear rings, designed to eliminate focus breathing and optical axis shifts. Native X-mount electrical contacts allow for distortion correction and seamless integration with camera-body data, making it suitable for professional video production. Cons include a strict lack of autofocus, absence of optical image stabilization, no weather sealing, and a relatively bulky, premium-priced design. For the full product specifications, visit DPReview.
