Laowa 1.4X FF Expander is specifically designed to expand the lens coverage from Super35 to full-frame without any loss in image quality. It also increases the effective focal length of the lenses by a factor of 1.4X and reduces the effective aperture of the lens by one stop.
Fully compatible with the OOOM and Proteus series, this expander is an excellent choice for switching between lenses and expanding their shooting capabilities as needed.
