01 — Front element

It begins with the glass.

A hand-ground aspherical front element, coated to pass light — and nothing else. Flare is not tamed here. It is designed out.

02 — Form

Machined from a single billet.

Every surface earns its place. Nothing is added for effect. The barrel is turned, anodised, and knurled by the same hands that calibrate it.
