How to Zoom in on Your Homemade Fisheye
A homemade fisheye lens is a cheap alternative to the costly ones produced by camera and optics manufacturers. While the image quality can't compete with a professional lens, the homemade fisheye is a fun way to experiment with a wide, distorted field of view. The fisheye effect is created by attaching a door peephole viewer to the lens of a point-and-shoot or DSLR camera. This combination causes vignetting, or dark, blurry corners in the resulting image. By zooming in slightly, you'll be able to reduce vignetting and increase image quality.

Tips & Warnings
Homemade fisheyes vary widely in construction, so mount yours carefully.
Use caution when mounting your fisheye to your DSLR lens to avoid scratching the front element. Using a filter will protect your lens from scratches.
