7Artisans' fisheye for MFT — 15mm equiv at f/2.8 with manual focus for creative photography.
The 7Artisans 7.5mm f/2.8 is a compact fisheye prime for Micro Four Thirds, providing 15mm equivalent with approximately 180 degrees of diagonal fisheye coverage. Budget Chinese optics for creative fisheye effects.
Optically adequate for a fisheye — the extreme barrel distortion is intentional. Sharp in the centre. The f/2.8 aperture is useful for low-light fisheye work. Manual focus — the massive depth of field makes focus largely uncritical.
Micro Four Thirds mount (also available for Sony E and Fujifilm X). No electronic contacts. Manual focus and aperture. Approximately 200g. All-metal construction. No filter thread — protruding front element.
Available used very cheaply. A fun creative lens — fisheye effects for skateboarding, VR stitching, and creative work. The massive DOF means focus is easy. For budget fisheye experimentation on MFT.
