Description
Capture massive landscapes with the Irix Blackstone 15mm f/2.4. This ultra-wide-angle rectilinear lens provides a stunning 110 degree field of view, making it an ideal choice for photographers who need to cover vast scenery without the distortion typical of extreme wide lenses. Built with a solid aluminum and magnesium body, this lens is designed for durability and protection in the field. Precision is at the heart of the Blackstone series. The lens features an optimized focus ring with an infinity click and hyperfocal scale to assist with manual focusing accuracy. To ensure high-quality images, the optical construction includes 3 high refractive lenses, 2 ED lenses, and 2 aspherical lenses. This setup minimizes ghosting and lens flare while maintaining a low distortion rate of 3.13%. Designed for outdoor use, the lens is weather sealed to offer resistance to the elements. It also includes Neutrino coating and engraved fluorescent markings for better visibility. Whether you are using the rear gelatin filter slot or a 95mm front filter thread, this lens provides the professional control needed for high-end photography.
