Tuning in on the Tunnel

This lens is a bit of magnetic magic. I originally purchased my Tunnelvision lens to use with my LC-A+, but I've ended up testing it with every camera on which it fits.

Technically, it’s just a .5x converter. That means that it will “convert” a cameras lens into one that is half it’s normal focal length. It effectively turns a 50mm lens into a 25mm lens… a 32mm lens into a 16mm lens! It was actually designed to work with digital camcorders which have smaller lens diameters and smaller sensors. The tunnel effect comes from being badly matched with the optics of a 35mm camera, but that’s OK! It gives pictures a bit of charm.

The lens comes with a set of stick on rings that you stick onto the camera. The lens itself attaches to the rings magnetically. It can also be taken apart to be used as a macro lens, but without a single reflex lens system it’s very hard to use. It’s hard to aim and hard to focus. I rarely use the macro capabilities of the lens.

Here’s the ring with the lens in waiting on a Mango camera:

It fits perfectly around the lens and turns the Mango into a wide-angle monster.

Here’s the Mango with the lens on:

Here are some before and after shots showing the same scene without the lens then with the lens:

For this shot I trapped some colored gels between the Tunnelvision lens and the magnetic ring. I did a triple-exposure using three different colored gels:

Here are some more shots using various cameras:
