Redesigned with a metal exterior under the Art category, this high-performance standard lens is designed exclusively for mirrorless interchangeable lens cameras and has the equivalent angle of view as a 60mm lens (35mm equivalent focal length) on the Micro Four Thirds systems and 45mm (35mm equivalent focal length) on the E-mount system. Two glass mold aspherical lenses, including a double-sided aspherical lens, provide excellent correction for all types of aberration. The inner focusing system corrects the fluctuation of aberration to maintain image quality regardless of the focal distance. Sigma’s Super Multi-Layer Coating reduces flare and ghosting as well as provides sharp and high contrast images even at the maximum aperture. The superior telecentric optical design improves the image quality throughout the frame. The optical design also allows the lens to be compact and lightweight. This lens benefits from a newly developed linear AF motor, which moves the lens elements directly without the need for gears or the drive of other mechanical parts.

This system ensures accurate and quiet autofocusing, making the lens suitable for video recording as well as still photos. The lens features a rounded 7-blade diaphragm creating an attractive blur to the out of focus areas of the image. This Sigma 30mm F2.8 DN has a minimum focusing distance of 30cm/11.8in and a maximum magnification ratio of 1:8.1, and comes in either a silver or black finish.

Image caption If Prince William and Kate had a daughter first, she would take precedence over younger brothers Sons and daughters of any future UK monarch will have equal right to the throne, after Commonwealth leaders agreed to change succession laws. The leaders of the 16 Commonwealth countries where the Queen is head of state unanimously approved the changes at a summit in Perth, Australia. It means a first-born daughter of the Duke and Duchess of Cambridge would take precedence over younger brothers. The ban on the monarch being married to a Roman Catholic was also lifted. Under the old succession laws, dating back more than 300 years, the heir to the throne is the first-born son of the monarch. Only when there are no sons, as in the case of the Queen's father George VI, does the crown pass to the eldest daughter.

By Duncan Kennedy BBC News, Perth Equal rights for women in the British Monarchy? It's quite a change. The new rules will reverse 300 years of tradition, custom and law, so it's a big royal deal.
