Overview

The 7Artisans 6mm F2 Fisheye is a manual focus circular style fisheye lens for APS-C and Micro Four Thirds mirrorless cameras. It is offered for Sony E, Fujifilm X, Canon RF, Nikon Z and Micro Four Thirds. According to 7Artisans, the lens covers an angle of view of 220 degrees, well beyond the 180 degrees of a conventional fisheye, and it is aimed at creative perspective work, night scenes and star photography.

Optical design

The construction has 10 elements in 8 groups. The maximum aperture is F2.0 and the aperture range runs to F16, with 9 diaphragm blades. 7Artisans compares the 220 degrees with the 160 and 180 degree angles of conventional fisheyes on its product page. The closest focusing distance is 0.1 m, which according to the manufacturer allows exaggerated close-up perspectives.

Focusing and handling

Focusing is manual, and the aperture ring has click stops. 7Artisans suggests the lens for creative shots in which subjects close to the lens stand out while the background stretches and expands. The F2.0 aperture gives a high light intake, which the manufacturer recommends for night scenes and star photography. The lens has no filter thread and no front filter support.

Build and size

The lens body is made of metal. It is 69 mm in diameter and 76 mm long and weighs about 418 g without front and rear caps.

The 7Artisans 6mm stands out through its 220 degree angle of view and its F2.0 aperture.

Verdict

The 6mm F2 Fisheye is a specialist lens for creative perspective work on small sensors.

It suits photographers who want an extreme look for astrophotography, interiors or close-up work, and who accept manual focus and the lack of front filters.
