Along with the new X-H1 camera, Fujifilm has announced two new X-mount lenses today: MK50-135mm T2.9 and MK18-55mm T2.9. The focal lengths differ, but the lenses have many features in common, so let’s take a look.
Both lenses cover Super 35 format. They are equipped with three independent lens control rings: focus, iris, and zoom, and the clickless iris. Both lenses are color matched to other Fujinon lenses, which enables smooth intercutting between different lenses. They are also same weight and length so you don’t need to rebalance your camera when you change from one lens to the other. Additionally, both lenses incorporate macro mode.
Let’s check out the full specs of both lenses.
