Set aperture and exposure according to scene requirements; the lens performs well at narrower apertures for maximum depth of field and sharpness. For close subjects use the minimum focusing distance of 0.275 m, keeping in mind perspective distortion typical of extreme wide angles.
Usage recommendations
For best results in landscape and architecture, use a tripod and stop down to f/8–f/16 to increase sharpness across the frame. Keep the lens weather seals clean and check for debris after outdoor use to maintain sealing performance.
