Japanese architect Hideyuki Nakayama teamed up with door knob manufacturer UNION to create this funky glass globe knob that gives you a fisheye view of the next room. Now all Nakayama needs to do is find some way to incorporate film and a shutter…

There’s a super rare Nikkor 6mm f/2.8 fisheye lens for sale on eBay. How much does f/2.8, 6mm, and a 220° field of view cost? A mere $34,020.

Aside from this uber-rare lens being uber-expensive, it’s also ridiculously heavy, weighing in at close to 11.5 pounds. Here’s what Photography in Malaysia has to say about this lens:

You are looking at one of the most gorgeous looking lens in 35mm SLR photography – a lens that can actually see behind itself! This series of lenses were originally developed for special scientific and industrial use where wider-than-180° picture coverage is required in surveillance work, photographing the interiors of pipes, boilers, conduits, cylinder bores and other constricted areas. But in applications such as advertising and commercial photography they are used extensively for dramatic effects.

To put the field of view in perspective, human vision is about 180°.

Bhautik Joshi, the guy who made the Phone-O-Scope that we tweeted a while ago, has a new do-it-yourself project for those of you who enjoy this kind of hack-ish photography project.

His latest project involves building a cheap fisheye lens using a peephole lens and a soda can.

Here are some sample photographs taken with the “tin cam”:

Built using a fisheye peephole as the main lens element and a decapitated soda can as the lens body (!), this attaches directly to my SLR camera. For well under US$20, I ended up with a lens that has nearly a 180-degree field-of-view, adjustable focus, a canon EOS mount, and due to it’s stylish and sleek exterior, can generate limitless amounts of admiration ridicule confusion.

To learn how to build one of these for yourself, head on over to the tutorial through the following link:
