Review

The NiSi 15mm f/4 Sunstar ASPH is an impressive ultra-wide angle lens designed specifically for the Canon RF mount. Known for its capability to deliver stunning images with a unique sunstar effect, this lens is perfect for landscape photography and creative captures that benefit from expansive depth and breadth.

Build Quality and Design

Right out of the box, the NiSi 15mm f/4 boasts a solid construction with a premium feel. The all-metal body gives it durability while remaining reasonably lightweight, making it a suitable companion for outdoor photography. The compact design is a significant plus for those who often travel with their gear, as it easily fits in typical camera bags without taking up too much space.

Optical Performance

When it comes to optical quality, the NiSi 15mm f/4 Sunstar ASPH excels. The lens design includes multiple high-quality glass elements that minimize chromatic aberration and distortion, resulting in sharp, clear images even at the extreme corners. Moreover, the lens's unique aperture blades create stunning sunstars when stopped down, offering photographers a creative tool for capturing dramatic sunrises or sunsets.

However, at f/4, some may find it a bit limiting for low-light conditions despite its ultra-wide angle. Users who are accustomed to faster apertures might find the need to raise their ISO sensitivity or utilize longer exposures to compensate.

Usability and Handling

Focusing is smooth, and the lens features a customizable lens hood that helps avoid flares and unwanted glares. The focus ring is well-damped and allows for precise manual focusing, which can be particularly beneficial when photographing intricate landscapes or when depth of field accuracy is crucial. However, the limited focal length may lead to a learning curve for those new to ultra-wide photography, as composition and subject placement take on added importance.
