IRIX Dragonfly 45mm f/1.4 45mm
A fast f/1.4 aperture combined with one aspherical and four HR elements delivers sharp, low-light imagery with controlled aberrations on full-frame Nikon F bodies. Its Dragonfly weather-sealed construction and focus lock mechanism provide a robust, tactile shooting experience in harsh conditions. This lens is best for portrait photographers who prioritize deliberate manual focus and shallow depth of field over autofocus speed.
