Product details

Metabones Contarex to Sony E-Mount Speed Booster 0.71x (Black Matt)

The Metabones Contarex to Sony E-Mount Speed Booster 0.71x (Black Matt) allows the use of Contarex lenses on Sony E-Mount cameras, widening the field of view by 0.71, increasing maximum aperture by 1 stop, and enhancing resolution for professional-quality imaging.

This adapter is designed for photographers wanting to utilize classic Contarex lenses on modern Sony E-mount cameras. Its advanced optics, designed by Caldwell Photographic in the USA (patent granted), optimize lens performance by reducing the effective crop factor, widening the lens's angle of view, and increasing maximum aperture by one stop.

It also improves MTF for sharper images and better contrast. The built-in aperture control ring allows precise manual adjustments, while the detachable Arca-type tripod foot is compatible with Arca Swiss, Markins, and Photo Clam ball heads for stable mounting. The Speed Booster is constructed for durability and long-term reliability, and its satin black finish provides a professional appearance.

This adapter is fully mechanical and does not support electronic communication, autofocus, or electronic aperture control. Note that Metabones is not licensed, approved, or endorsed by Sony or Contarex.
