7Artisans (Seven Craftsmen) just recently officially launched the 4mm F2.8 Fisheye fisheye lens suitable for APS-C film mirrorless cameras. Since the lens weighs only 201g, it is extremely light and portable. Enough to use with aerial photography of drones. While ensuring image quality, it will reduce the load on the drone, and of course the battery life will also be improved to a certain extent.
7Artisans 4mm F2.8 Fisheye uses a metal mirror body design, but unfortunately there is no electronic electric shock, so you can only focus on manually . equivalent focal length 6mm, with a 225-degree diagonal, can shoot creative fisheye perspective. Inside the lens, this lens consists of 8 sets of 10 optical structures, with a closest focus distance of 8.5cm. Because the physical focal length is short enough, even a manual focus mirror can easily obtain a long depth of field. If used with the DJI drone, it can capture a wide bird's-eye view anytime and anywhere. Of course, for a better shooting experience, the built-in 7Artisans 4mm F2.8 Fisheye's 7-aperture blades are segmentless design, which can adjust the aperture without pole to achieve accurate exposure. Currently, Canon EOS-M, Fujifilm X, Micro 4/3 and Sony E mount versions are available, and will be available for sale today, with a price of US$150, approximately 1,067 yuan .
