Athena Prime 25mm T1.9 – Canon RF-Mount

Athena Prime 25mm T1.9

The NiSi Athena 25mm T1.9 impresses with its remarkable image quality. With a generous aperture range from T1.9 to T22, it enables clear and sharp images with minimal distortion.

The front diameter of 80 mm and the filter thread of 77 mm open up a variety of filter options. The optical performance is characterized by precise and vivid color reproduction. This versatile lens is ideal for landscape, architecture, and creative photography, meeting the high demands of professional photographers and filmmakers.

Videography at the highest level 

Thanks to precise micro-contrast optimization and remarkable minimization of chromatic aberrations, these lenses deliver unparalleled clear image quality, accurately reproducing even the finest image details. This brings every shot to life. Furthermore, the Athena Prime series offers excellent performance in low-light conditions, meaning that whether you are filming at dusk or indoors under challenging lighting conditions, the lenses always deliver optimal performance.

Precise focusing and creative control with Athena Prime lenses 

The focus ring of the Athena Prime lenses allows for precise and smooth focusing. With an impressive 300-degree focus rotation, filmmakers can make fine adjustments and achieve optimal sharpness - crucial for creative manual focusing and image composition. 

The Athena Prime lenses are specifically designed to minimize focus breathing and maintain the framing and composition. The result is smooth and even focusing. Fluorescent scales optimize readability in low-light conditions, in the studio, or during night shoots, making focusing even easier.

Optimal image quality in full frame 

The lenses are designed for full-frame cameras with a 46 mm image circle to optimally utilize the entire sensor area and provide high image quality up to the edges - ideal for high-resolution full-frame cameras. 

The Athena Prime lenses offer exceptional optical performance, excellent sharpness, and contrast for clear, vibrant images. Precise construction and high-quality optical elements minimize distortion and aberrations.

Drop-In Filter 

Another special feature of the NiSi Athena Prime Cinema lenses is the integration of drop-in filters in the E-, RF-, and L-Mount versions (PL-Mount is equipped with a rear filter holder). This innovative filter solution allows filmmakers to insert ND or Vario-ND filters directly into the lens without having to change the front lens. This speeds up the filter change and simultaneously reduces the risk of dust and dirt on the optics.
