A fast and bright wide-angle prime, the Canon RF-mount Laowa 15mm f/2 FE Zero-D Lens from Venus Opticsis a rectilinear lens with a sophisticated optical design to effectively limit distortion. The bright f/2 maximum aperture makes this lens especially useful for astrophotography and low-light use, and when paired with the 5.9" minimum focusing distance, distinct shallow depth of field imagery can also be produced. The optical construction includes three extra-low dispersion elements and two aspherical elements to control both chromatic and spherical aberrations for greater sharpness, clarity, and reduced color fringing. A Frog Eye Coating has been applied, too, to repel dust and moisture from the front element of the lens to benefit working in trying environmental conditions. Additionally, the manual aperture ring can be de-clicked for smooth, silent aperture changes to suit video applications, and the front of the lens is threaded to accept 72mm screw-in filters.
