A Chinese manufacturer called ZY Optics has announced the 135/1.4 Mitakon Speedmaster lens, claiming that it's the fastest 135 mm lens in the world. According to Amateur Photographer magazine it will be available in Leica L-mount as well as Sony A, Sony E, Canon EF, Nikon F, Fujifilm G, and Pentax K mounts for Β£1,000.
The minimum focus distance will be 1.5 metres, it will weigh 3 kg, and it will have a 105 mm filter thread.
It's not a lens that I would be interested in but I thought that other members might find it interesting and possibly attractive.
Pete.
