The careful design also minimizes focus breathing, which is crucial for professional videography.

Optical Performance

The Canon RF50mm F1.8 STM Lens excels in optical performance with features like optimized lens placement and coatings that help deliver outstanding color balance while minimizing ghosting and flare. The PMo aspherical lens is engineered to suppress aberrations, ensuring sharp images across various conditions.

Conversely, the SIRUI Night Walker 35mm focuses on delivering outstanding optical performance even at its maximum T1.2 aperture. This lens achieves excellent sharpness and well-controlled aberration, making it suitable for cinematic work. The construction of 11 elements in 10 groups further enhances its optical capabilities, providing filmmakers with a high-quality image.

Aperture and Low-Light Performance

With its f/1.8 aperture, the Canon RF50mm is ideal for low-light photography and creative background blur. This feature is particularly useful for capturing portraits and detailed shots in various lighting conditions. The lens’s ability to perform well in low-light scenarios makes it versatile for many different types of photography.

The SIRUI Night Walker 35mm stands out with its exceptionally large T1.2 aperture, which is particularly beneficial for filmmakers working in dimly lit environments. This lens allows users to shoot without excessively high ISO settings, resulting in cleaner images with less noise. The combination of a fast aperture and excellent bokeh quality makes it an outstanding choice for expressive video footage.

Focal Length Versatility

The Canon RF50mm F1.8 offers a fixed focal length of 50mm, making it a great all-around lens for various photography situations. This focal length is often referred to as a “standard” lens, as it closely resembles the natural perspective of human vision. It’s suitable for everything from casual snapshots to more formal portrait photography.

In contrast, the SIRUI Night Walker 35mm provides a focal length equivalent to 49mm in full-frame terms, which is slightly wider than the Canon lens. This makes it particularly suitable for documentary work and capturing broader scenes while still allowing for portrait framing. The SIRUI lens’s 35mm focal length is ideal for filmmakers looking to emphasize human subjects in their storytelling.

However, if your focus is primarily on cine work and you require a lens with a larger aperture for video, the SIRUI may justify the additional cost.

Which should you buy?

Choosing between the Canon RF50mm F1.8 STM Lens and the SIRUI Night Walker 35mm S35 Manual Focus Cine Lens ultimately depends on your specific needs and shooting style. If you are primarily a photographer looking for a versatile and budget-friendly option, the Canon lens is the clear winner.
