Laowa 4mm f/2.8 Fisheye 4mm
72 out of 100 high confidence 46 reviews
The Laowa 4mm f/2.8 fisheye is a fun, ultra-wide lens that delivers a unique circular image at a very low price. Users praise its sharpness and build quality, but note that it requires careful handling to avoid including fingers, grips, or lens markings in the frame. Compatibility with full-frame cameras is limited, often requiring cropping, and manual focus can be tricky. Overall, it's seen as a great value for creative or occasional use.
