We read somewhere that fishing is the UK's most popular "participation sport", so now you can join in too. On a full-frame camera such as a D3, D700 or even film, this 8mm fish-eye lens produces a circular image with a 180-degree field of view. On cameras with DX sensors you don't get a full circle but you do still get a fairly extreme fish-eye effect.

Great fun if you can get the hang of using it properly.
