The 12–25mm lens can capture more of the visual spectrum than human eyes can see, and the perspective effect of ultra–wide angle can draw attention to the foreground while enhancing the depth of field and tension. Additionally, the exceptional optical design makes it possible to significantly control the distortion when shooting at maximum wide-open aperture, making it ideal for creating majestic and surreal images.
