Chinese lens manufacturer Venus Optics has launched the Laowa 4mm f/2.8 Circular Fisheye Lens for Micro Four Thirds (M43) cameras. Due to the effective focal length increase of 2x, the lens is equivalent to the 8mm circular fisheye lens found on most DSLR systems. Specifically designed for Micro Four Thirds cameras, the 4mm creates an extremely distorted fisheye perspective. It is extremely compact at only 45mm long and lightweight at only 135 grams. It is expected to be available in the coming weeks and will cost around £249.
_210° angle-of-view _
The lens boasts an ultra-wide 210° angle-of-view so is quite a specialist optic, but will suit those shooting creative effects, panoramics and astro-photography. A full 360º panorama can also be achieved using as few as two images as opposed to shooting six or more images with conventional fisheye lenses. This lens is also particularly good for VR photography, shooting virtual tour and spherical panoramas.
_Fast f/2.8 aperture _
The ultra-fast f/2.8 aperture makes it an ideal option for astro-photography and shooting in low light conditions. The depth-of-field is so deep that no focusing operation is required. Setting the focusing ring at infinity focus and stopping down the lens to around f/5.6 ensures everything will be in focus.
Featuring seven elements in six groups, the new 4mm claims to offer outstanding sharpness throughout the frame. Along with the 210º ultra-wide angle, photographers can either remove the fish-eye effect in post-processing or crop the image to transform it into a rectilinear image.
Focus as close as 3.14in (8cm) from the image sensor
Photographers can take advantage of the ultra-close focusing distance to capture some heavily distorted and impactful shots.
