New $40 fisheye E-mount lens from a chinese company

Our reader YC just spotted a new teaser for a Fisheye MFT lens made by a chinese manufacturer:

Some info from a Chinese mirrorless forum:

 This guy claimed that his little team from Shenzhen, China is designing a super compact fisheye macro lens for E/X/M43 mount. The length is only 6mm. On APS-C it’s a 180 diagonal fisheye. The aperture is F8 and you cannot stop down. The minimum working distance is only 1 cm. It contains 1 AA glass. The corner sharpness wouldn’t be worse than the other fisheye lenses on the market (at least he said so).
 They have finished the first prototype. Several samples are included in the thread. The price is 299 CNY = 43.44 USD. They’ll start a fund raising program from March on the Chinese website JD.com (kind of like Amazon). The early bird price is 249 CNY = 36.18 USD. The product is planned to be shipped from June. But I guess they don’t have any plan for oversea market yet.
