Lens Overview — Bower 14mm T3.1

The Bower 14mm T3.1 Ultra Wide Cinema Lens for Samsung NX is a manual-focus prime lens designed for APS-C mirrorless cameras using the Samsung NX mount. With a fixed focal length of 14mm and a maximum aperture rated at T3.1, this lens is built around cinema-style T-stop measurement, making it a practical choice for videographers who need consistent, repeatable exposure values across a set of lenses. At 14mm, it falls firmly in the ultra wide-angle category, making it well-suited for capturing expansive scenes, environmental footage, architecture, and interiors.

The lens is a prime design, meaning there is no zoom capability, which typically contributes to optical consistency at its single focal length. Autofocus is not supported — this is a fully manual-focus lens, in keeping with its cinema-oriented design philosophy. Image stabilization is listed as none, so any stabilization would need to come from the camera body or an external rig.

Weighing 544 grams, it has a solid, substantial build. With no filter thread size listed in the specifications, buyers should verify filter compatibility before purchase. This lens is specifically designed for the Samsung NX camera system and is categorized as a mirrorless lens.

Frequently Asked Questions — Bower 14mm T3.1

Does this lens work with autofocus on Samsung NX cameras?+
No. The Bower 14mm T3.1 is a manual-focus-only lens — autofocus is not supported. This is consistent with its cinema-oriented design, where precise manual control over focus is standard practice.
What camera mount does this lens use?+
This lens is built specifically for the Samsung NX mount and is designed for APS-C format mirrorless cameras in that system. It is not compatible with other mounts without an adapter.
Does this lens have image stabilization?+
No. The specifications list image stabilization as none. Users who need stabilization for video work will need to rely on an external gimbal, rig, or any in-body stabilization their camera may provide.
Why does this lens use a T-stop rating instead of an f-stop?+
T-stops measure the actual light transmitted through the lens, accounting for any light lost to internal elements and coatings. This makes T3.1 a cinema-standard rating useful for matching exposure precisely across multiple lenses on a shoot.
What is the weight of this lens?+
The Bower 14mm T3.1 weighs 544 grams according to its specifications, giving it a substantial feel consistent with a cinema-style lens build.
Can I use filters with this lens?+
The specifications do not list a filter thread size, so standard screw-on filter compatibility cannot be confirmed from the available data. Buyers should verify filter attachment options directly before purchasing.
