DZOFilm Catta Zoom 70-135mm T2.9 (E-mount + L-mount) Cinema Lens Zoom Lens Used only once indoors, in almost new condition. Features a quick mount exchange system, allowing for mount changes in under a minute without tools. Also includes a shim set for adjusting the lens's back focus. The photos posted are of the lens used with a Blackmagic Pyxis (camera body not included). This listing includes the E-mount lens body and a separately purchased L-mount. If you would like the L-mount installed before shipping, please let me know. (However, as noted, it's easily swappable in 1 minute without tools.) —— 【Key Features】 ■ Combines High Durability and Light Weight The 35mm-80mm T/2.9 weighs only 1.53kg, and the 70mm-135mm T/2.9 weighs less than 1.6kg. To achieve this lightness, polycarbonate and glass fiber, which combine lightness and durability, are used for the shell. The precise parfocal design makes it ideal for shooting various genres such as live shows, film production, vehicle photography, and documentaries. It can easily handle scenes with a lot of movement. Gimbals such as the DJI RS 2 and Zhiyun Crane 3S can also be used. ■ Beautiful Round Bokeh and Fine Details With 16 aperture blades and an aperture range of T2.9 to T22, it achieves a rounded, smooth bokeh. There is no so-called F-drop, allowing for more natural zooming. Furthermore, the minimum focusing distance is 0.74m for the 35-80mm model and 0.76m for the 70-135mm model, allowing you to capture details and features more clearly from closer to the subject. ■ Improved Breathing Even with DZOFilm cinema lenses released up to now, focus breathing (change in angle of view due to focus operation) has been minimized, but with the Catta Zoom this time, focus breathing is almost unnoticeable. The angle of view remains constant even when the focus is changed within the same cut, allowing for more natural shooting.
