Zeiss has added a new 25mm f/2.4 wide angle prime lens, to its Loxia manual-focus line-up for Sony’s full frame E-mount cameras.

The new lens features a  Distagon optical design that has been specially developed for Sony’s high-resolution, full-frame sensors. It contains 10 elements in eight groups, including one element with an aspheric optical surface and two elements made from special glass with anomalous partial dispersion. It is effectively free from distortion.Like the 21mm f/2.8 and 35mm f/2 wide-angle lenses in the Loxia family, it is designed for manual focusing and manual aperture selection. The minimum focus is 25 cm and apertures can be stopped down to f/22. The aperture ring includes a DeClick mechanism.

Zeiss lenses are characterised by focusing rings with a large rotation angle which enables high precision. Changes are immediately visible in the viewfinder. The lens includes a distance scale and depth of focus indicators to provide additional support for manually focusing.

The new lens features a precision-engineered full-metal casing, metal focus and aperture rings and a tough front bayonet and filter screw. A special sealing ring on the bayonet also protects the interface between the camera and the lens. Detailed information about the new lens can be found at http://lenspire.zeiss.com/en/loxia-24-25/.
