LAS VEGAS — Think the only serious, affordable quiver of lenses available for iPhone 5/S iPhoneography are the ones from Olloclip? Nope. Wrong.

One of the best pieces of iPhonography kit we’ve played with is the Olloclip, a tiny gizmo that clips onto the corner of the iPhone 4/S and gives photographers the use of three additional lenses; now it’s finally available for the iPhone 5.

FOR SALE>£100,000 ($161,000): 6mm ƒ2.8 Fisheye-Nikkor

That’s what you’ll see at the top of Grays of Westminster’s used Nikon manual-focus lens listings. The London dealer has gotten its hands on this incredible chunk of glass, a 5.2-kilo (11.5-pound) mountain of a lens that makes the camera behind it look like a vestigial tail.

One disadvantage of using an iPhone or iPad as a camera is that you’re stuck with a single, fixed focal-length lens. Optical zoom can work only so far before even Instagram photos start to look bad, and phones with built in optical zooms tend to resemble actual cameras.

The solution? Add-on lenses. Today, we’ll take a look at Photojojo’s four-in-one set of fisheye, macro, wide angle and telephoto lenses. These accessory lenses stick magnetically over the iDevice’s camera, changing the point of view.

The Olloclip ($70) is a clip-on device for iPhone 4 and 4S which gives the built-in camera lens a little more flexibility for wide angle and close-up shots.

It includes three lenses. At one end, the largest of the three is the fisheye. At the other end you have a general-purpose wide angle. Unscrew this, and you uncover a tiny macro lens nestling underneath.
