7Artisans has released its new fully-manual 4mm F2.8 circular fisheye lens for APS-C mirrorless camera systems and compatible drones.
The lens, which lacks any sort of communication protocols and requires complete manual control, offers a roughly 6mm full-frame equivalent focal length with a 225º field of view. It’s constructed of 10 elements in eight groups, uses a seven-blade aperture diaphragm, has a minimum focusing distance of 8.5mm (.3”) and uses a de-clicked aperture ring.

The lens is made of metal and weighs just 201g (7oz). It’s available for Canon EOS-M, Fujifilm X, Micro Four Thirds and Sony E-mount camera systems. 7Artisans also notes it can be paired with DJI drones for fisheye images captured from the sky.
The 7Artisans 4mm F2.8 fisheye lens is available for $150 through the company’s online shop.
