Add-On Kit for Athena Prime Set

This three-lens add-on kit completes the original Athena Prime five-lens set for full-frame cinema cameras. It supplies an 18mm T2.2, a 40mm T1.9 and a 135mm T2.2, all sharing the same PL mount. Filmmakers who already own the core set gain wider, standard and short-telephoto focal lengths without changing lens families.

Thermal and Power Behaviour

These are passive cine lenses with no internal electronics, fans or motors, so they generate no heat and draw no power during operation. Silent manual focus and iris rings add zero acoustic noise to a set. The only thermal consideration is ambient temperature affecting barrel expansion, which is normal for all-metal cinema glass.

Build, Mount and Daily Handling

Each lens uses a PL mount with identical iris and focus ring positions to the rest of the Athena range, allowing fast lens swaps on matte boxes or follow-focus rigs without re-gearing. A magnetic rear filter holder is included for quick ND or diffusion changes. The set is not for shooters needing autofocus, electronic metadata or lighter-weight mirrorless-native mounts.

  • Gain fast 40mm T1.9 for low-light scenes

Questions about this item

How are the 18mm, 40mm and 135mm lenses mounted and what step is often missed?

Attach each lens to a PL-mount camera body, secure the locking collar fully, then match the iris and focus gear rings to your follow-focus and matte-box positions so they align with the rest of the Athena set

What maintenance will the 18mm T2.2, 40mm T1.9 and 135mm T2.2 lenses need over time?

Clean front and rear elements with a microfibre cloth and lens fluid, check iris and focus gear rings for play, and have a technician re-lubricate the helicoids if focus rotation stiffens

Which limitation appears first during long takes with the 40mm T1.9 wide open?

The shallow depth of field at T1.9 makes critical focus holding the limiting factor, while minimal focus breathing keeps field-of-view shifts negligible
