What We Like
+World's first full-frame F1.4 diagonal fisheye lens with exceptional sharpness across entire 180° field of view
+Specialized astrophotography features including MFL switch, lens heater retainer, and rear filter holder for long exposures
+Outstanding optical performance with minimal coma, chromatic aberration, and sagittal astigmatism even at wide-open F1.4
+Premium Art series build quality with dust/splash-resistant construction and robust magnesium alloy tripod socket
+First autofocus fisheye lens for Sony E-Mount and Leica L-Mount mirrorless cameras
+Extremely fast aperture enables creative control of distortion through camera tilt in diagonal fisheye format
Worth Knowing
−Extremely niche product with limited applications; very expensive at $1,999 USD
−Large and heavy (1,360g/48oz), making it impractical for extended hand-held shooting
−Corners show soft focus at very close distances, which may limit certain macro applications
−No front filter threads due to fisheye design; requires rear filters, limiting accessory compatibility
