NiSi Lens 9mm F2.8 For APS-C MFT-Mount

NiSi Lens 9mm F2.8 For APS-C MFT-Mount – 113° Ultra Wide Angle with f/2.8 Aperture

The NiSi 9mm f/2.8 Ultra Wide Angle ASPH lens offers a true super wide-angle view for APS-C mirrorless systems and MFT. It delivers a 113° field of view and a bright f/2.8 aperture, making it useful for landscapes, architecture, and night skies. Moreover, the lens remains compact and easy to carry, weighing only 364g.

Optical design and image quality

This lens uses a complex optical formula with 14 elements in 12 groups to control distortion and deliver high resolution from the centre to the corners. Additionally, NiSi applies its SA+ anti-reflection film technology to improve light transmittance and reduce lens flare and stray light. As a result, the lens produces clean images with low coma and ultra-low chromatic aberration, which is especially important for astrophotography and high-contrast scenes.

Aperture, sunstars and bokeh

The aperture range runs from f/2.8 to f/16. The f/2.8 maximum aperture allows subject separation and a pleasing shallow-depth-of-field effect when appropriate. Furthermore, the lens has a 10-bladed diaphragm. This design produces clean sunstars across the aperture range, from f/2.8 to f/16.

Construction, handling and durability

NiSi builds the lens with a compact metal construction that keeps it robust while remaining portable. In addition, they add a rubber gasket at the bayonet to provide all-weather sealing. Therefore, the lens is a suitable choice for photographers who need to shoot in varied outdoor conditions.

Close-up capability, filters and video use

You can focus as close as 0.2m, enabling interesting close-up wide-angle perspectives. Also, the lens accepts 67mm filters, which allows you to use landscape and creative filters for extended control over scenes. For video, NiSi de-clicks the aperture ring so you can make smooth exposure adjustments while recording, improving usability for filmmakers.
