A little while back, Laowa (A.K.A. Venus optics) announced a very exciting new 9mm f/5.6 full-frame lens. (Laowa already has a 9mm 2.8 lens for crop sensors, but this lens is for full-frame and lower aperture).
One of the exciting features of this lens is that it is a Rectilinear, low distortion lens and does not create any fish-eye distortion. It is not as distortion-free as Laowa’s Zero-D, but still has very (very!) low distortion for a 9mm lens.
We managed to get our hands on a few sample photos for the lens made with various cameras, click on each image for larger resolution.
And here are some photos that taken using the lens by Richard Wong
