Crazy

The Skink pinhole lens is a simple construction with exchangeable pinhole plates and the typical pinhole image quality.

The Muse is the latest version of original Lensbaby. It uses the same glasses as the Composer. It's pretty hard to control the results, but a lot of fun to use.

The Composer is the "advanced" Lensbaby with better control. It's still a very odd lens with it's warped sharpness and exchangeable glasses.

My first ever fisheye lens, and a great performer. Both the mechanics and the optical quality is good, and the lens produces a stunning 180 degree vista on a full frame body

A tilt&shift lens that you can pay. It's very well built, but fully manual - both focus and aperture.

A fisheye is a great supplement to any lens lineup, and for Nikon DX owners this is the ticket.
