A 15mm f/1.7 prime for X-mount brings an expansive, ultra-wide view to APS-C in a compact, bright package. Review pages describe a lightweight design intended for travel, cityscapes and creative low-light work, with the fast aperture enabling shorter shutter speeds at night and shallow depth of field for dramatic foreground emphasis. On modern X-series bodies, 15mm encourages bold compositions at close distances, pulling in context while keeping subjects prominent through perspective and careful framing. The build is designed to stay portable and nimble, supporting hand-held shooting and gimbal setups for video. Wide open, it favors expressive rendering; stopped down, it provides depth and edge-to-edge clarity for landscapes and architecture. For creators who want to explore night skies, interiors or sweeping scenes without carrying a large zoom, this lens offers a practical balance of brightness, size and simplicity. It invites experimentation with leading lines, near-far relationships and ambient light, rewarding careful technique with images that feel immersive and immediate.
