Lens Overview — Mitakon Zhongyi 17mm T1

The Mitakon Zhongyi 17mm T1 Speedmaster Cinema Lens is a manual-focus prime lens built for the Micro Four Thirds camera system. With a maximum aperture of T1 — an exceptionally fast light transmission rating for any lens format — this wide-angle cine lens is purpose-built for shooters who demand low-light performance and precise exposure control in cinematic workflows. The T1 aperture designation means the actual light transmission through the lens is measured and confirmed at T1, giving cinematographers and video operators reliable, consistent exposure when cutting between lenses on set.

Designed specifically for Micro Four Thirds mount cameras, the lens covers the Micro Four Thirds format and fits directly onto compatible MFT bodies without any adapter. As a prime lens at 17mm in the wide-angle category, it delivers a fixed focal length that encourages deliberate composition. The lens is manual focus only, which aligns with professional cine practices where precise, repeatable focus pulls are essential.

It accepts 77mm screw-in filters, accommodating a wide range of cinema and photographic filter systems. Weighing 597g, the lens has a substantial, robust feel appropriate for a dedicated cine build.

Description — Mitakon Zhongyi 17mm T1

The Mitakon Zhongyi 17mm T1 Speedmaster Cinema Lens is a 17mm wide-angle prime built natively for the Micro Four Thirds camera system. Its headline specification is a maximum aperture of T1 — a measured transmission aperture that confirms the lens passes an exceptional quantity of light to the sensor, making it a strong option for dimly lit shooting environments and cinematic productions where consistent, accurate exposure is critical. As a manual focus only lens with no autofocus and no image stabilization, it is engineered around the deliberate, controlled workflow of professional cine production.

The lens accepts 77mm screw-in filters, offering compatibility with a wide range of professional filtration options. Weighing 597g, it has a solid, cine-appropriate build. With a prime configuration at a fixed 17mm focal length in the wide-angle range, this lens suits architectural interiors, environmental storytelling, and any scenario where a wide, fixed field of view is the creative intent.

The Micro Four Thirds mount ensures direct compatibility with MFT cameras without adapters.

Frequently Asked Questions — Mitakon Zhongyi 17mm T1

What camera mount does this lens fit?+
The Mitakon Zhongyi 17mm T1 Speedmaster is built for the Micro Four Thirds mount. It is designed for use with MFT-system cameras and covers the Micro Four Thirds format natively, requiring no adapter on compatible bodies.
What does the T1 aperture rating mean compared to an f-stop?+
A T-stop (transmission stop) is a measured value of actual light passing through the lens, rather than a calculated geometric aperture. The T1 rating on this lens means light transmission is confirmed at T1, giving cinematographers highly accurate and consistent exposure readings — an important distinction when matching lenses on a multi-camera production.
Does this lens have autofocus or image stabilization?+
No — this lens is manual focus only and has no image stabilization. These characteristics are standard for dedicated cine lenses, where manual focus pulls are preferred for precise control on set.
What filter size does this lens use?+
The lens features a 77mm filter thread, which is a common professional size compatible with a wide selection of ND, polarizing, and effect filters.
Is this lens suitable for photography as well as video?+
While the lens is classified as a cine type and is manual focus only, its Micro Four Thirds mount and 17mm wide-angle prime focal length make it usable for still photography as well. Photographers comfortable with manual focus will be able to use it on MFT bodies for stills.
