• APS-C Format Lens: The Ultra wide-angle 4mm f/2.8 fisheye lens is designed for APS-C Sony E-mount mirrorless cameras and provides an 6mm equivalent focal length.
• Ultra-wide Angle of View: Exceptionally wide 225° angle of view along with a circular fisheye design produces a highly distorted image for creative applications as well as to stitch images together for full 360° panoramas.
• Ideal Aperture: Bright f/2.8 maximum aperture is well-suited to working in low and difficult lighting conditions.
• Compact Construction: The lightweight and small design make this lens suitable for use on drones as well as being ideal for VR imaging, action sports filming, or virtual tours.
• Manual focus design: The lens is a manual focus design that offers a minimum focusing distance of 0.85m. A multi-layer coating enhances colour, reduces glare, prevents ghosting, and ensures a sharp image.
