TTArtisan 7.5mm F2.0 8mm
Its f/2 aperture and 180° angle of view on APS-C sensors deliver dramatic distortion and strong low-light capability, while the unique front cap creates a clean circular fisheye image on full-frame bodies. The all-metal build and manual focus rings provide a tactile, durable feel at a budget-friendly price point. This lens is best for photographers experimenting with surreal portraiture and exaggerated close-ups who don't require autofocus.
