Lens Overview — DZOFilm 20-70mm T2.9

The DZOFilm 20-70mm T2.9 is a parfocal cinema zoom lens designed for Micro Four Thirds mirrorless cameras. Built specifically for cine applications, it covers a 20-70mm focal length range — a versatile standard zoom spread — and maintains a constant maximum aperture of T2.9 throughout the entire zoom range, which is essential for consistent exposure when pulling zoom during a shot. As a cinema-type lens, it features fully manual focus operation, which aligns with professional video production workflows where focus pullers demand precise, repeatable control.

The lens mounts natively on the Micro Four Thirds system, making it directly compatible with MFT mirrorless cameras without the need for an adapter. Weighing in at 1100g, this is a solidly built optic with the heft expected of a dedicated cinema lens. A 77mm filter thread provides a standard front diameter for matte boxes or screw-on filters.

There is no image stabilization, so shooters will rely on their camera body or rig-based stabilization. The parfocal characteristic — maintaining focus as the focal length is adjusted — is one of its standout practical advantages for run-and-gun or scripted cinema production alike.
