Dust Donut adds a weather seal to Canon EF lenses

Dust and moisture are the natural enemies of DSLRs. If they get into you camera they can cause all sorts of problems ranging from dust on the sensor and image degradation, to fungus growing inside a lens. The Dust Donut is a simple idea designed to solve the problem of non-weather-sealed lenses by adding a seal between your camera and lens. Read More

Kata Revolver-8 camera bag stores lenses like a loaded pistol

A professional photographer needs to be able to grab their camera and any equipment at a moment's notice, and Kata has been producing camera bags with this in mind for years. For its newest lightweight bag, the company seems to have taken some inspiration from a style of handgun, to produce a backpack that can help swap lenses much more efficiently. The Revolver-8 PL backpack stores a DSLR camera and dispenses up to five lenses from a rotating internal chamber that can be readily accessed through a side opening. Read More

MIT produces new metamaterial that acts as a lens for radio waves

We expect the world to be predictable. Water flows downhill, fire burns and lenses bend light in a particular way. That worldview took a jolt as Isaac Ehrenberg, an MIT graduate student in mechanical engineering, developed a three-dimensional, lightweight metamaterial lens that focuses radio waves with extreme precision. That may not seem too disturbing, but the lens is concave and works in exactly the opposite manner of how such a lens should. Read More

GRIN optical technology could mean better implantable lenses

Although many people may think that the lenses in our eyes are just like those found in cameras, there is in fact one key difference between the two – while man-made lenses have just a single index of refraction, meaning that they only bend light in one direction, our natural lenses refract light by varying degrees. This is why artificial implanted lenses, such as those used to treat cataracts, can create visual distortions. A new technology, however, now allows for the fabrication of lenses that work just like the ones in our eyes. Read More

Nikon announces 70-200mm f/4G ED VR full-frame lens

The recently announced 70-200 f/4 is an important lens for Nikon – not only does it plug a longstanding gap in the manufacturer's lens lineup, but it's also the debut for the third generation of Nikon’s Vibration Reduction (VR) technology. Considerably smaller and lighter than the f/2.8 alternative, the new lens still boasts a respectable constant f/4 aperture and promises up to five stops of image stabilization. Read More

HiLO lens provides a new angle on iPhone photography

A lot of digital cameras have LCD screens that can be swiveled around independent of the camera body, making it a lot easier to get high- and low-angle shots. Photographers using an iPhone or iPad, however, are stuck with an unswivel-able screen. That’s where the HiLO lens comes in. It’s a right-angle lens that attaches to an iDevice’s existing lens, allowing users to shoot up, down or to either side while still being able to view the screen. Read More

Lensbaby adds Spark to creative lens range – let the blurring begin

Although there’s an almost infinite number of effects that can be added to already-taken photos using software, there’s definitely something to be said for the on-location creativity that comes with good ol’ optical in-camera effects. That’s why Lensbaby designed the Spark, a new lens that it announced today. Spark is intended to capture images “that have a sweet spot of focus surrounded by beautiful artistic blur.” Read More
