Lens manufacturer Shenzhen Dongzheng Optics Technology has announced the Kerlee 35mm F1.2 – which it claims is the fastest 35mm designed for full-frame SLR cameras.
Featuring a choice of clicked or silent aperture adjustments, for both stills and movie production, the company says it will produce units with mounts in Canon EF, Nikon F, Sony E and Pentax K fittings.
The lens uses 11 elements in 10 groups and includes two high refractive index lenses and one ED low dispersion element. The company says the closest focusing distance is 0.3m / 1ft, but optical performance is said to be at its best when the subject is 1-5m / 3.2-16.4ft from the camera. The smallest aperture is F22 and the lens also features a depth of field scale.
Pricing has yet to be released, but more information can be found on the Dongzheng Optics website.Read more at http://www.australianphotography.com/news/kerlee-35mm-f1-2-the-world-s-fastest-lens#41j2K6Pj9cP1Set2.99
