The Nikon 16mm Fisheye lens is a quite remarkable piece of tech in that it can actually record a full 180°. This sucker can see sideways! But straight from the camera the best I could get was this:
Not as wide as hoped and of course a little dull and dark... put it through DxO PL6, adjusted a few settings and discovered that there was more photo that was not originally revealed:
I then decided to squeeze a bit more out, played with the manual distortion buttons a bit as well and got this very wide and less fisheye looking photo:
Along the way I found that this lens really has very limited use but if used creatively in the right setting it can deliver interesting results. Not every bodies cup of tea, but interesting none the less.
