Shoot superwide 250° or circular images with the Entaniya HAL 250 3mm Superwide Fisheye Lens MFTfrom Entaniya. This Micro Four Thirds-mount/format lens produces a 250° or 180° field of view depending on your camera's sensor size and aspect ratio. Instead of an iris ring that controls the aperture blades, this f/2.8 lens uses a set of f/4, f/5.6, f/8, and f/11 aperture rings that must be manually swapped with the included tool. You can also adjust the exposure using the included ND0.6 and ND1.2 filters. See the chart on the Entaniya site for detailed sensor coverage information.

The HAL 250 lens boasts a superwide 250° when using the entirety of your Micro Four Thirds sensor. Select a 16:9 aspect ratio to make the image appear wider by cropping the top and bottom. This reduces the vertical angle of view to 180°, flattening the top and bottom edges.
