Optics manufacturer Kipon has announced an updated version of its 40mm F0.85 ultrafast prime, the Ibelux 40mm F0.85 Mark III.

This third-generation lens improves upon its predecessor with an updated optical construction that consists of ten elements in eight groups. Compared to the Ibelux 40mm F0.85 Mark II, KIPON says the Mark III version ‘has totally new coatings both inside and out’ to reduce flares and ghosting, and fixes ‘the irregular light reflection/diffusion problem’ that led to purple fringing.

The lens, which is available with mounts for Canon EOS R, Fujifilm X, Leica L, Micro Four Thirds, Nikon Z and Sony E-mount APS-C camera systems, features a 10-blade aperture diaphragm, has a minimum focusing distance of 75cm (29.5"), uses a 67mm front filter thread and has an aperture range of F0.85 through F22. Manual focus is driven by a Swiss-German mechanism and the focus ring offers 270º of rotation.

The Kipon Ibelux 40mm F0.85 Mark III is constructed of an aluminum outer barrel with a brass core and stainless steel mount. It measures 74mm (2.9") in diameter by 128mm (5") long and weighs 1,150g (2.5lbs).
