Exploring the Unique Characteristics of Cinema Lenses

Introduction

• The discussion focuses on comparing two types of lenses, industrial and cinema lenses, particularly exploring their value and optical characteristics.

Lens Comparison

• Lens A: Industrial lens costing ~¥1000 (~$150).
  • Sharpness is targeted for product inspection and lacks focus mechanism, bokeh, or flare control resulting in limited versatility.
• Lens B: Cooke vintage cinema lens, expensive to rent, with a soft, hazy look.
  • Higher price justifies the distinctive vintage style and optical legacy of Cooke lenses.

The Vintage "Cooke Look"

• Exploration of why older, softer lenses can still be appealing.
• The Cooke Panchro/i Classic FF and SP3 lenses are examined for their cinematic qualities and consistency in motion picture shooting.

Optical Characteristics

• Spherical Aberration:

  • Creates unique bokeh and image softness.
  • Historical limitations led to overcorrection in older lenses, adding a soft glow.
  • Nikon 135mm f/2 DC lens showcases this feature with adjustable aberration controls.

• Field Curvature:

  • Not flat focus, but curving, guiding viewer’s attention.
  • Introduces edge softness, commonly found in lenses including Cooke lenses.

• Lens Flare:

  • Deemed both as imperfection and artistic quality.
  • Different lenses, like the Panchro, produce unique flares, such as the "Peacock Flare."

Modern vs. Vintage

• Modern lenses, like Sony's 50mm f/1.4 GM, employ aspherical elements for smoother bokeh and optical perfection.
• Conversely, vintage lenses preserve a "character" or stylistic property cherished in certain cinematographic contexts.

Color Reproduction

• Lenses differ in color casting, which isn't entirely correctable in post-production.
• Consistency across a lens set is vital for easier grading and shot matching.

Conclusion

• Lenses for cinematography offer diverse creative options distinct from photographic sharpness.
• Embrace different lens styles to enrich storytelling, supported by historical and contemporary advancements in optical design.
