What We Like
+Unique zoom fisheye for mirrorless systems—only fisheye zoom ever made for mirrorless and fastest fisheye zoom ever made
+Dual fisheye effect in one lens: circular at 8mm (180°) and rectangular at 15mm (~175°) without changing lenses
+Constant f/2.8 aperture throughout zoom range enables excellent low-light performance and astrophotography
+Exceptional close focus of 16cm (6.3 inches) with 0.23x magnification enables creative macro-style distortion
+Solid all-metal construction with smooth, tactile manual controls and excellent build quality
+Competitively priced at $699—roughly half the cost of discontinued Canon/Nikon DSLR fisheye zooms and available for modern mirrorless mounts
Worth Knowing
−No autofocus, no electronic contacts, and no EXIF data recording—fully manual operation requires careful focus confirmation
−No weather sealing or optical image stabilization despite all-metal build
−Sharpness at 15mm requires stopping down to f/5.6–f/8 for edge-to-edge crispness; off-center subjects blur at f/2.8
−Harsh, soap-bubble bokeh with specular highlights; awkward-looking intermediate focal lengths (9–14mm) between the two practical extremes
