Nikon reveals a lens that captures wide and telephoto images simultaneously

Original Article ↗ Hacker News Discussion ↗

Scope and Intended Use

  • Lens is described as an industrial/automotive component, not a photographer-oriented product.
  • Target use: vehicle situational awareness / ADAS (wide view for nearby pedestrians/cyclists plus detailed view far ahead).
  • Some commenters note Nikon’s core strength is optics and see no obvious need for exotic sensors/ISPs beyond the lens design.

Lack of Images and Article Critiques

  • Multiple people note there are no sample images anywhere (even in Nikon’s press release).
  • This is viewed as suspicious or “clickbait-like,” though others assume images are embargoed until CES.
  • Some complain the linked site is ad-heavy, hard to navigate, and thin on technical detail.

Optical Design Speculation

  • Ideas floated include:
    • Variable focal length across the image plane (higher magnification at center).
    • Concentric optics: telephoto center + wide “donut” fringe.
    • Beam-splitting prisms or pick-off mirrors feeding multiple sensors.
    • Anamorphic or “reverse-corrected” / foveated projection concentrating resolution in the center.
  • Several note significant downstream processing will be needed to make the raw output useful or human-viewable.
  • Some emphasize that whatever the scheme, true single-axis alignment (no parallax) is key.

Cropping vs Telephoto and Optical Limits

  • Debate on whether telephoto is just a crop of wide-angle:
    • One side: in ideal optics, yes; perspective differences in practice come from camera distance, not focal length.
    • Others argue real lenses, f-numbers, diffraction, and distortion complicate the equivalence.
  • Related discussion on depth of field, aperture equivalence, angular resolution, and why high-megapixel sensors alone don’t replace optical magnification.

Potential Impact and Extensions

  • Some think 200+ MP sensors plus this lens could be powerful; others question processing and optical sharpness in a moving car.
  • A few see possible future smartphone applications: foveated capture, simultaneous wide/tele capture, and after-the-fact zoom.
  • Others note user downsides: larger files, storage pressure, and complexity of managing multiple versions per shot.

Overall Sentiment

  • Interest and curiosity from optics/vision-minded commenters.
  • Skepticism due to missing technical details and images; many defer judgment until CES reveals more.
