The Fujinon MK50-135mm T2.9 for Sony E is a lightweight cine-style zoom for Sony E-mount cameras. Key features include:
Fast T2.9 clickless aperture
Parfocal with minimum focus breathing
Geared focus, iris, and zoom rings
Native Sony E-mount
Featherweight. The first thing you’ll notice when you pick up the Fujinon MK50-135mm T2.9 for Sony E is that it’s beyond light. It weighs in at just north of two pounds, which means you can mount it without an additional lens support. Its light weight also makes it a prime candidate for gimbal work.
High-Quality Optics. The lens features a fast T2.9 clickless aperture, controlled by nine rounded blades. It’s color matched to compliment Fujinon’s higher-end offerings, and the 28.5mm diameter image circle covers the APS-C/Super 35 sensor format with a 16:9 aspect ratio.
Cine Style. Unlike many other Sony E-mount “cine” lenses, the MK50-135mm is truly a cinema lens with a full cinema feature set. The focus, iris, and zoom rings all have industry-standard 0.8 gears. The focus ring gives you precise control over pulls and follows with 200° of rotation, while the iris ring is de-clicked with a smooth action allowing you adjust exposure mid-shot. This lens has a short flange focal distance, but it allows flange focal distance adjustment so you can fine tune it to the camera you’re using. It offers a macro-focus mode that shortens the minimum focusing distance from roughly four feet to just under three feet.
Parfocal This term is thrown around a good bit, but many lenses that claim it are not truly parfocal. Instead, they’re close enough that many won’t notice. Well not this one. The MK50-135mm is a true parfocal lens.
