Switzerland-based company TH Swiss has introduced the Irix 15mm F2.4 lens for DSLR cameras. The manual focus lens features a 'neutrino' coating that helps keep ghosting, color aberration and flare under control.
The 15mm F2.4 is designed for full-frame cameras. It offers a minimum focusing distance of 28cm/11in, and the focus ring provides a 'click' tactile feedback when focused to infinity. The lens is composed of 15 elements in 11 groups. Three of the elements have a high refractive index (HRI) elements while another two feature extra-low dispersion (ED) glass. A pair of glass aspherical lenses ensure minimal distortions and aberrations while improving image edge brightness and overall image quality, says the company.
The Irix 15mm is offered in two varieties: 'Blackstone' and 'Firefly.' The Irix Blackstone features a magnesium and aluminum body able to withstand 'extreme conditions,' while the Irix Firefly model is, according to the company, the lightest lens in its class. Both versions of the lens will launch this spring in Canon EF, Nikon F and Pentax K mount; price hasn't been revealed at this time.
Price: TBA
