If your camera is exposed to excessive humidity, you'll want to make sure it's dried out properly when you pack it away – because it's never fun to find lens-killing fungus on your expensive glass. While most of us do this by carefully wiping down equipment and throwing a few silica gel packets into a kit bag, BRNO has released a range of dehumidifying lens and body caps to do the job.

Sony has revealed a pair of new E-mount lenses for its NEX range of mirrorless cameras. A 20mm F2.8 pancake, while not the prime telephoto some NEX shooters have been crying out for, gives a good wide walk-around lens, and the new (but not quite new) 18-200mm F3.5-6.3 OSS boasts impressive video-friendly credentials.

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

Some people think photography is about capturing images which are perfectly composed, tack-sharp, distortion-free and have amazingly life-like colors. If you're one of them, look away now! The DSLR Wheel of Filters is a plastic lens and wheel attachment which lets photographers use their DSLR to take decidedly lo-fi and filtered snaps which look like they've come from a toy camera.

We've seen multi-lens attachments for iPhone before, of course, notably the iPhone Lens Dial, but the iPhone 5's change in form factor inevitably ushers in a new wave of such devices. The TurtleJacket PentaEye from Turtleback is among the early runners and riders, and crams in an impressive four lenses to the Lens Dial's three. Read More
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
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
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
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
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
