Review: Adlens Adjustables glasses change focus to suit the user

It's always handy having a spare pair of glasses on hand, but paying for a second set of prescription specs is something that most of us would prefer not to do. Well, that's where Adlens Adjustables come in. They're inexpensive glasses that can be focused by the user to (more or less) match their prescription. We recently gave them a try, and can tell you that they work ... but you probably won't want to use them as your primary glasses.

Ford unveils 2015 Focus in Geneva

Ford hasn't done too bad with its Focus line. In 2012, it surpassed the Toyota Corolla as the world's best selling car model and, according to Ford, it still holds the crown with 12 million sold worldwide. The economical all-round commuter car enjoys a good reputation with reviewers and drivers, so it's not surprising that Ford doesn't go in for radical redesigns, but the company does tweak a bit now and then. This year at the Geneva Motor Show, Ford is unveiling its latest Focus with a slightly sleeker design package containing some new engine and other technologies for the European market. Read More

FocusMaker brings follow focus to any DSLR lens

If you've ever tried changing focus between subjects while shooting a video with your DSLR, you'll know that auto-focus will often leave you with a stuttering and noisy clip, while using your hand on the lens in manual focus can be tricky. Follow focus systems try to make this easier and better by adding a handle to change focus smoothly, and marker points to move between. The newly-launched FocusMaker is the latest example, which promises the fastest and most accurate focusing of any affordable rack focus system. Read More

Lytro camera gains manual controls with new firmware

The Lytro light field camera – which lets users adjust a photo's focus after it's been taken – has gained the manual controls photographers have been craving, with a new firmware update. This means users can now stretch their creative shutter finger and adjust things like shutter speed or ISO (remember there's no need to adjust aperture, which is a constant f/2.0), and turn on or off the neutral density (ND) filter.

So, you’re looking at that one photo you took, and wishing that the flower in the foreground was in focus instead of the person behind it? Well it’s no big deal, just go in and shift the focus. Oh yeah, that’s right, you can’t ... but you will be able to soon. California-based Lytro, Inc. announced today that its consumer light field camera is now available for preorder, and should be shipping early next year. It is the first camera of its kind made for the general public. Read More

Mini autofocus lens mimics the human eye

Mobile phone cameras generally aren't known for their fantastic image quality. One of the reasons for this is the fact that most of them have fixed-focus lenses, as opposed to the autofocus lenses on all but the cheapest stand-alone cameras. The phone cameras partially compensate by using a small aperture to maintain a good depth of field, but this limits their use in low-light situations. Of course, their lenses could automatically focus by moving in and out (like those on larger cameras), but this would draw considerable power from the phones' batteries. Now, however, Norwegian scientists have unveiled a low-power autofocus lens for mobile phone cameras, that works like the human eye. Read More

DSLR Solutions brings follow focus to film-makers on a budget

One of the challenges faced by serious videographers is the ability to “land” the camera’s focus ring on the right spot when shifting focus between two onscreen objects. If you’re shifting between a person in the background and a flower in the foreground, for instance, it can often take several tries before getting a take where you don’t focus right past the flower, or overcompensate by slowly creeping up to it. Professionals use a device called a follow focus to avoid this problem, but they can often be prohibitively expensive for amateurs and low-budget film-makers. Fortunately, however, those people now have an alternative – the DSLR Follow Focus. Read More

Lytro light field camera lets users adjust a photo's focus after it's been taken

For those of us who grew up with film cameras, even the most basic digital cameras can still seem a little bit magical. The ability to instantly see how your shots turned out, then delete the ones you don’t want and manipulate the ones you like, is something we would have killed for. Well, light field cameras could be to today’s digital cameras, what digital was to film. Among other things, they allow users to selectively shift focus between various objects in a picture, after it’s been taken. While the technology has so far been inaccessible to most of us, that is set to change, with the upcoming release of Lytro’s consumer light field camera. Read More

New portable camera sees inside solid materials and structures

A research team from the Missouri University of Science and Technology (Missouri S&T) has succeeded in creating a portable scanning system that's capable of looking inside objects or structures and revealing hidden secrets. Using technology similar to that used for full body scans at airports, the new transmission mode camera system can detect, collect, process and display millimeter-wave and microwave signal information in real time and at adjustable focus points between the transmitter and collector aperture. The whole setup is powered by a single laptop-sized battery, with the results being displayed on a notebook screen. Read More
