DZOFilm LingLung 10-24mm T2.9 MFT vs Rokinon 24mm T1.5 Cine DSX

These are different tools, not rivals at the same job. The DZOFilm 10-24mm is a parfocal M4/3 zoom that holds focus through the whole 10-24mm range, so it suits gimbal, run-and-gun and documentary work where you reframe fast. The Rokinon 24mm T1.5 is a fast full-frame prime with weather-sealed mounts and de-clicked gears, better for low light and shallow depth of field on a single focal length. Owners of the Rokinon praise the T1.5 speed and smooth focus throw but note it is soft wide open and heavy for its size; the DZOFilm is favored for its parfocal behavior and compact body, though T2.9 limits it in dim light.

• Choose the DZOFilm 10-24mm if you shoot on M4/3 and need one lens that zooms from wide to normal without losing focus.
• Choose the Rokinon 24mm if you want a fast T1.5 prime for low light and shallow depth of field, and your camera has a full-frame or larger sensor.
