Product Overview
Laowa 20mm F4 Zero-D Shift is a manual-focus ultra wide-angle prime lens for Canon EF-mount, Canon RF-mount, Fujifilm G-mount, Leica L-mount, Nikon F-mount, Nikon Z-mount, Pentax K-mount, and Sony E-mount. It covers the medium format (44x33) image circle. Introduced by Laowa in 2022, it has 16 elements in 11 groups.
Manual focus may be limiting to some, but purists will find it much more engaging. There are also fewer things to go wrong on the long run.
As an ultra wide-angle prime lens that happens to have relatively small maximum aperture, it is best suited for landscape photography. Even though the lens is not stabilized, at this focal range it does not usually matter. In fact, some may be able to get cleaner corners without image stabilization. Those who like sunstars (sun bursts) will be pleased by the lens' even-numbered aperture count, though conversely those who find sunstars distracting may have the opposite feeling.
Importantly, this Zero-D Shift is a shift lens (unlike tilt-shift lenses, it cannot tilt), which is ideal for architectural photography.
