Product Information
Full details
The NiSi Athena 135mm T2.2 Cine Lens is an exceptional choice for filmmakers and cinematographers using the Canon RF system who prioritize cinematic bokeh and razor-sharp optical performance. This lens excels at portraiture and subject isolation, providing high-end image quality with minimal focus breathing; however, its manual-focus nature requires significant user proficiency and may not be suitable for run-and-gun projects requiring autofocus.

FAQs
Does this lens support autofocus?
No, the NiSi Athena 135mm is a manual focus-only cinema lens.
Can I use standard 77mm filters?
Yes, the lens features a standard 77mm front thread for screw-on filters.
Is this lens weather-sealed?
While robust, it is not officially rated for extreme weather; use caution in heavy rain or dusty environments.
Does the focus breathing match other lenses in the set?
Yes, the entire Athena series is designed to have minimal and consistent focus breathing across all focal lengths.
What is the benefit of the drop-in filter mount?
It allows you to use ND or other filters behind the lens, which is especially useful when using clamp-on matte boxes.
Troubleshooting
Image appears soft on focus peaking
Ensure the lens is mounted securely and verify that the focus ring is calibrated correctly with your follow-focus system.
Visible dust spots on the sensor
Check the rear element and the rear drop-in filter mount; clean both with a professional lens cleaning kit.
Focus ring feels stiff during operation
Check if any external follow-focus gear is exerting excessive pressure on the lens barrel; adjust the tension of your motor.

Setup, Compatibility & Care
This lens is specifically designed for the Canon RF mount. To install, align the white dot on the lens with the mounting indicator on your camera body and rotate until it clicks.
For maintenance, use a high-quality lens blower to remove dust from the glass before using a soft microfiber cloth. Always store the lens in a temperature-controlled, dry environment. When using the drop-in filter mount, ensure the filter is fully seated to prevent light leaks or physical interference with the sensor area. Avoid touching the internal glass elements, and always attach the rear cap when the lens is not in use.
