(FT3) Sigma 50mm f/1.4 MFT lens specs

Last year Sigma teased the launch of a new fast prime. SAR reports about the likely specs of this lens:

“Sigma 50/1.4 APS-C E-mount: 9 blades, less than 300g, around $600. Most probably around NAB 2018.”

This lens will be released for different mounts like Sony E, Fuji X and Micro Four Thirds.
