What We Like
+Astonishingly wide 132-degree field of view for a rectilinear full-frame lens
+Compact and lightweight design at 463g with built-in metal hood
+Excellent flare resistance and low vignetting compared to competitors
+Affordable pricing at $479 compared to alternatives like the Laowa 9mm f/5.6
+Manual focus with deep depth of field eliminates need for autofocus at ultra-wide focal length
Worth Knowing
−No front filter thread; wide curved element prevents standard filter compatibility
−Soft corners at f/5.6 requiring stopping down to f/11+ for sharpness across frame
−Noticeable barrel distortion especially at close distances, requiring post-processing correction
−Modest f/5.6 aperture limits low-light and astrophotography performance

About This LensThe 7Artisans 9mm F5.6 ASPH is a manual focus prime lens compatible with full-frame sensors, with an ultra-wide angle of up to 132°, ideal for photographing landscapes and architecture. It's a full-frame compatible rectilinear prime lens that's super-small but packs in a humungous field of view, featuring 132-degree viewing angle in its small build with a solid metal construction. At a very reasonable asking price, this nicely crafted and very useful kit bag addition works well for capturing sweeping vistas in landscape photography, architectural interiors when space is tight, and vlogging. | |
