Sigma 4.5mm f/2.8 AF HSM EX DC Circular Fisheye price graph

    It is necessary to create a 180 degree lens. 1.5 crop across the entire frame width.
    9 June 2015 
    I dreamed of a one hundred and eighty degree lens. I bought it two years ago. In fact, a lens for a 1/2 matrix, but not a 1.5, although if there were lens glass with a slightly larger diameter, it would be quite possible to get 180 degrees horizontally across the entire width of the matrix. Vertical 180 degrees is not necessary. Now I hardly use it and I can’t sell it - no one is stupid!
    180 degrees, focusing, aperture
    A speck of light on the matrix is too small, occupying less than half of its area. poor resolution.
