Yongnuo will soon announce the new 85mm f/1.8 FE autofocus lens. This will be their second E-mount lens after the 50mm f/1.8 APS-C (here on Amazon).
Here is the google translated text from an original Chinese text I received:
Small size, lightweight design
The maximum diameter and length of the lens is about 67×88mm, and the net weight is only about 346g. The lightweight design is good for long-term handheld shooting and video recording.

F 1.8 large aperture
Flexible use of F1.8 large aperture, easy to obtain soft blur effect, can also use low sensitivity and higher shutter to shoot in low light environment.
9 optical lenses in 8 groups, nano multilayer coating
It adopts 8 groups and 9 -element optical structure design, and the lens nano-multilayer coating process , which effectively improves the light transmittance and suppresses the ghost image and glare of backlight .
Low dispersion lens

Metal bayonet, gold-plated contacts
The use of high-precision metal bayonet and gold-plated contacts effectively improves signal conductivity and corrosion resistance, and is durable. At the same time, it allows the camera and lens to maintain reliable communication, and realizes functions such as autofocus, aperture control, and EXIF information transmission.
