  • Completes Athena Prime set with three matching focal lengths
  • 18mm T2.2 captures expansive scenes with wide perspective

  • 135mm T2.2 compresses distance for detailed portraits
  • Uniform ring positions enable fast lens changes without re-rigging

Add-On Kit for Athena Prime

This three-lens add-on kit completes the original Athena Prime five-lens set with 18mm T2.2, 40mm T1.9 and 135mm T2.2 focal lengths. It is built for filmmakers who already own the core set and need wider, normal and short-telephoto coverage on full-frame sensors. The uniform T-stop range keeps exposure consistent across the expanded lineup.

Canon RF mount and matched gear positions

Each lens uses a native Canon RF mount and shares identical iris and focus ring positions with the rest of the Athena range. This allows rapid lens changes without repositioning follow-focus gear or matte boxes. Minimal focus breathing maintains a stable field of view during racking, reducing the need for post-production correction.

Focal range from 18mm to 135mm

The 18mm covers expansive scenes, the 40mm T1.9 handles general narrative work with a slightly faster aperture, and the 135mm reaches tight portraits and detail shots. All three maintain full-frame coverage and consistent T2.2 speed except the 40mm at T1.9. The set does not address focal lengths below 18mm or beyond 135mm, so productions requiring ultra-wide or long-telephoto perspectives will need additional glass.

Questions about this item

How do I verify the 18mm T2.2 lens is performing correctly after mounting it on my Canon RF camera?

Check that the aperture ring clicks smoothly to T2.2, confirm focus marks align at infinity, and shoot a test chart to ensure even sharpness across the frame with minimal breathing during focus pulls.

What comes in the NiSi ATHENA PRIME Add-On kit box and what must I purchase separately?

The kit includes the 18mm T2.2, 40mm T1.9, and 135mm T2.2 lenses plus a filter holder; you will need to buy matte boxes, follow-focus gears, or additional filters separately.

Which focal length from the 18mm, 40mm, and 135mm options should I choose for my next shoot?

Select the 18mm T2.2 for wide establishing shots, the 40mm T1.9 for natural perspective and low-light work, or the 135mm T2.2 for compressed portraits and detail isolation.
