NiSi 135mm ATHENA PRIME Full Frame Cinema Lens T2.2 (RF Mount)

The NiSi 135mm ATHENA PRIME T2.2 is the longest focal length in the Athena Prime cinema series, built for the Canon RF Mount. Despite its larger size, its micro-contrast, color, iris position, and focus-ring position are matched to the rest of the series so it drops into a multi-lens set without extra recalibration. The T2.2 aperture gives clean subject isolation against a soft background, suited to close-ups in documentary and narrative work.
