TTArtisan has announced the details of a new 23mm f/1.4 wide-angle prime lens with a classic look designed for APS-C camera systems. The lens offers a 35mm equivalent focal length and is available for an array of APS-C camera systems.
The new TTArtisans 23mm f/1.4 is perfect for portrait and street photography because of its greater depth and greater visual impact. In low-light environments, a large aperture can also help output high-quality photos with low noise.
The manual lens is constructed of eight elements in six groups, including three high-refractive-index elements and one low-dispersion element. It has an aperture range of f/1.4 through f/16, uses a 10-blade aperture diaphragm, has a minimum focusing distance of 20cm, and uses a 43mm front filter thread. Depending on what lens mount version you go with, the lens weighs between 222–225g. All models will measure 60mm in diameter and 40.5mm long.
