From AstrHori: 

> Excellent Lens for Starry Sky - This full-frame fisheye lens has an ultra-wide viewing angle and a large aperture of F2.8, which reduces noise in the night scene and makes the picture more pure and transparent; excellent coma control keeps the star points on the edges round. 
> 
> Superior Optical Design - The optical structure of 11 elements in 8 groups effectively improves the problem of image degradation at the edge of the fisheye lens, and better creates excellent landscape photography works.
> 
> Diagonal 185° Ultra-wide Angle - With a 185° ultra-wide field of view, it can accommodate more images, making landscape photography more shocking.
> 
> Distortion and Correction - The unique exaggeration and distortion perspective of fisheye makes it applicable to many interesting and cool scenes. Such as performances, skiing, skating, racing and other activities. Moreover, correction software can also be used to correct fisheye distortion pictures into ultra wide angle pictures, which can be used for both purposes.
