Two scientists at the University of Rochester have taken invisibility cloaking back to basics. Their novel arrangement of four standard, off-the-shelf lenses keeps an object hidden (and the background undisturbed) as the viewer moves up to several degrees away from the optimal viewing angle.  Read More

The smartphone microscope, in use at the PNNL lab

Suppose you were a first responder, who got called out to investigate a suspicious substance found in a public place. Instead of having to transport that material back to the lab, wouldn't it be better if you could just take a microscope image of it with your smartphone, email that image off to a remote lab, then receive the analysis within just a few minutes while you were still on location? Thanks to a very inexpensive new phone attachment developed at the US Department of Energy's Pacific Northwest National Laboratory (PNNL), that could soon be possible.  Read More

The IBELUX 40mm f/0.85 claims the title as the fastest volume production lens in the world

Mirrorless camera owners in search of fast glass and razor-thin depth of field have a new king of wide-aperture lenses to drool over in the form of the Handevision IBELUX 40mm f/0.85. It's the fastest volume production lens in the world, and the manufacturer claims it'll give you an image similar to an f/1.2 lens on a full frame camera.  Read More

The Fujinon XF 18-135-mm is the first weather-resistant XF lens from Fujifilm

Fujifilm has launched its first weather-resistant XF lens for the X-series lineup of interchangeable-lens cameras. The new lens, which would pair particularly well with the weather-tough Fujifilm X-T1, offers a versatile focal range and features an impressive five-stop image stabilization system which uses high precision gyro sensors.  Read More

The Discovery Wall at Weill Cornell Medical College

A new digital installation has been unveiled in the window of the foyer at Weill Cornell Medical College (WCMC) in Manhattan. The Discovery Wall is a display made up of 2,800 mini LCD screens each placed behind a curved lens, and its content varies depending on the distance from which it's being viewed.  Read More

An image captured using the new lens

Night-vision security cameras could be getting a lot less costly, thanks to the discovery that their lenses can be made from silicon. Ordinarily, thermal infrared camera lenses are made from materials such as germanium and chalcogenide, which are much more expensive.  Read More

Researchers from the Center for Research and Advanced Studies (CINVESTAV) in Mexico have developed a pair of glasses that use a combination of ultrasound, GPS, stereoscopic vision and artificial intelligence to help the visually impaired to navigate their environment. The device, perhaps the most sophisticated of its kind, is slated to reach mass production early next year and will likely cost up to US$1,500.  Read More

Close-ups taken using a regular smartphone camera's digital zoom (left), and with the Core...

Although people may speak about zooming in with smartphone cameras, what they're doing isn't actual "zooming" in the telephoto-lens sense of the word. That's because almost all phone cameras just have a digital zoom, meaning that in order to get in closer on the subject, the phone just enlarges the pixels from the middle of the frame. The result is a grainy, crappy photo. While it is possible to squeeze optical zoom lenses into phones, Tel Aviv University spinoff company Corephotonics has developed a sleeker solution, that utilizes the combined output of two compact lenses.  Read More

Dr. Steve Lee, with some of his easy-bake lenses

Microscope lenses are typically made either by grinding and polishing glass discs, or pouring polymers into molds – both techniques can be quite involved, which is reflected in the price of the finished product. Now, however, a scientist from Australian National University has devised a new lens-making process, in which drops of silicone are simply baked in an oven. The resulting lenses can be used for a variety of applications, yet are worth less than one cent each.  Read More

The Fujifilm TCL-X100 tele-conversion lens gives a 50-mm equivalent focal length

Photographers using Fujifilm's X100 and X100S will soon be able to get closer to the action, without getting closer to the action, after Fujifilm revealed a tele-conversion lens for the popular cameras. The TCL-X100 attaches directly to the front of the retro-styled shooters and increases their focal reach by a factor of 1.4x.  Read More
