Probably, the other recently announced lenses (40mm and 100mm) had one for firmware updates. What’s neat about these lenses is that they contain a USB port, allowing owners to update the firmware of the lens from home to keep it up to date in the areas of compatibility and performance.
On the manual lens at F8 I get around 2 feet to infinity in focus with the subject at 5 feet, but if I wanted to shoot at f2.8 it's 3.5 to 8.5 feet in focus, so it's ok but AF would help there. It's ok for landscapes and far distances but I'vve shot a lot of street close up with mine using f8 and focus set to around 3-4 feet.
China have long made top quality products, but it's taken a while for them to acquire both the technology from others and to create enough confidence that they can produce high-end products under their own brands.
