Cooke SP3 18mm T2.4 Full-Frame Prime Lens ( Sony E, RF, L,M)

"The Wide-Angle Challenge in Modern Cinematography

Wide-angle lenses often compromise between distortion control and optical character, forcing filmmakers to choose between technical precision and artistic flair. Standard 18mm optics frequently exhibit chromatic aberration in high-contrast scenarios and lack the nuanced fall-off that creates dimensional depth.

Optical Engineering Meets Cinematic Heritage

The Cooke SP3 18mm T2.4 resolves these limitations through:

Full-frame coverage optimized for 43.3mm sensors, maintaining sharpness across Sony A7IV, FX3, and FX6 imaging planes

Interchangeable mount system (E/RF/L/M) enabling multi-platform compatibility without optical degradation

T2.4-T16 aperture range with 9-blade iris for smooth bokeh transitions

Dual non-linear focus scales (feet/meters) offering precise manual control down to 0.8m MOD"

1. Which cameras support the SP3 18mm's interchangeable mounts?
The lens ships with Sony E-mount and provides free RF-mount conversion. Leica L/M mounts require separate purchase. Verified compatible bodies include Sony FX3/FX6 and Canon R5C.

2. What protection does the warranty offer?
Cooke provides a 5-year manufacturer warranty covering optical defects. The lens ships in a flight-ready case with humidity-controlled foam.

3. How does this compare to Sigma 18mm T2.5 Cine?
While both cover full-frame, the SP3 maintains 0.8 MOD gears and matches Cooke's Panchro series color science. The Sigma lacks interchangeable mounts and weighs 890g.

4. What maintenance prevents coating damage?
Use microfiber cloths with Cooke-approved cleaning fluid. Avoid touching the rear element during mount changes. Store in the provided case when humidity exceeds 60%.

5. Why choose Cooke over Chinese cine lenses?
Cooke's multi-coating process reduces veiling glare by 37% compared to budget alternatives, while the anodized shell withstands 200% higher impact forces
