A new Nikon patent hints at tech to make bright aperture lenses smaller, but you might already have it in your Z-mount lens

Summary

Nikon has patented a dual focusing-group optical system intended to enable the creation of brighter and more compact lenses. This system uses two groups of elements that move independently, which helps manage aberrations and distortion more effectively than single-group systems. However, this design appears to be already implemented in Nikon's Z 35mm f/1.2 S and Z 50mm f/1.4 lenses, suggesting the patent may not reveal entirely new technology. The patent application date predates the release of these lenses, supporting the idea that the technology has been in use for some time.

Key points

• Nikon patent reveals a dual focusing-group system for lenses.
• This system aims to make bright aperture lenses more compact and improve optical correction.
• The technology appears to be already used in Nikon's Z 35mm f/1.2 S and Z 50mm f/1.4 lenses.
