A spherical fisheye with a full 180-degree angle of view makes mundane subjects look far out. Has a spring-loaded filter holder that accepts drop-in gelatin filters.
An updated version of Sigma's 8mm f/4 spherical fisheye, this is the field's widest circular fisheye with autofocus. It's also among the last Sigma film-era lenses to be upgraded with coatings that suppress reflections from digital sensors ("DG"). It captures a 180-degree field of view, with exaggerated perspective and dramatic linear distortion, especially along the frame edges. For full-circle images, you need a full-frame film or digital SLR; APS-scaled sensors crop into the top and bottom of the frame when the camera is oriented horizontally.
