Overview

The Brightin Star MF 10mm F5.6 II APS-C Fisheye is a very small manual focus fisheye for APS-C and Micro Four Thirds mirrorless cameras. Brightin Star quotes a 173 degree angle of view and offers it in black and silver for Sony E, Nikon Z, Fujifilm X, Canon RF, Canon EF-M and Micro Four Thirds. It appeared in May 2026 as the second version of this 10mm design. The lens is aimed at travel, street, vlog and creative shooters who want a fisheye look at very low weight.

Optical design

According to Brightin Star the lens has 7 elements in 5 groups. The aperture is a single value, F5.6, and the maker lists no blade count, so there is no adjustable diaphragm. The angle of view is 173 degrees. The minimum focus distance is 0.12 m. The maker lists no filter size, so the front element cannot take filters.

Focusing and handling

Focusing is manual with a ring that carries a distance scale. Brightin Star promotes a hyperfocal design for fast point-and-shoot work: when the focus label is set to 1 m, the lens is at its hyperfocal point, according to the maker's product images. Because the aperture is fixed there is no aperture ring, and exposure is controlled through the camera and the ISO. The lens has no autofocus and no stabilizer.

Build and size

This is a light lens, and the maker highlights a weight of 132 g for the Sony E version. Other mounts range from 120 g for Micro Four Thirds to 148 g for Nikon Z. The diameter is about 57 mm for most mounts and 64 mm for Canon RF and Nikon Z, with lengths between 31 and 35 mm, according to the maker's hand-measured drawings.

Where it fits

Earlier versions of this 10mm are not in the database. For APS-C fisheye shooting, the Brightin Star MF 7.5mm F2.8 IV APS-C Fisheye offers a wider view and a faster aperture at roughly twice the weight. Other options in the database are the 7artisans 7.5mm F2.8 Fisheye, the TTArtisan 7.5mm f/2 Fisheye, the Samyang / Rokinon 8mm F2.8 UMC Fisheye II and the Kamlan 8mm F3.0 Fisheye.

Pros and cons

Pros

Very light at 120 to 148 g
173 degree view and close focus at 0.12 m
Six mounts, black or silver
Hyperfocal marking makes quick shooting easy

Cons

Fixed F5.6 aperture, so it is slow in low light
No aperture control and no filter thread
Manual focus only
Narrower view than the 7.5mm F2.8 option

Verdict

The Brightin Star MF 10mm F5.6 II APS-C Fisheye is a compact, simple fisheye that trades control for weight and convenience. It suits daylight shooting where its fixed aperture and hyperfocal setting work well. Anyone who needs a fast aperture or night-sky performance should look at the faster 7.5mm option instead.
