Sigma have announced the development of a 1.2x tele conversion lens that is exclusively designed for the Sigma dp3 Quattro large-sensor compact camera. When attached to the front of the lens, it magnifies the focal length of the lens by 1.2 times (60mm / equivalent to 90mm on a 35mm format), and does not change the f/2.8 aperture value. The Sigma FT-1201 Conversion Lens has an optical formula comprising 4 elements in 3 groups, and maintains excellent rendering performance while offering a different focal length. Do note that the minimum focus distance and maximum magnification ratio are both affected by attaching this conversion lens. Pricing and availability are to be confirmed.
