How tough can it be? LensRentals looks at why it's so hard to make lenses

Why can't you just make them better? It sounds like a reasonable question until you start unpacking exactly what it entails, and that's exactly what Roger Cicala does in the latest LensRentals blog post. As usual, the closer he looks, the more complicated the question becomes. So why can't everyone just (repeatably and affordably) make lenses, you know... better? Read more

The Raw and the cooked: pulling apart Sony's Raw compression

A Raw file is a Raw file, right? Well, not exactly. Lately, there's been a lot of talk and a lot of anger about the compression Sony uses in its Raw files. Compressed Raw files aren't uncommon, but they're usually compressed in a way that retains all the original 'raw' data from the sensor. That doesn't seem to be the case with Sony's latest cameras.

Opinion: The future of DSLR or: how I learned to stop worrying and love the ILC

Despite some sales growth, mirrorless isn't taking over photography. Equally, DSLRs aren't flying off the shelves the way they used to. But if you've found yourself arguing about whether mirrorless is the future, you've probably been addressing the wrong question. DPReview's Richard Butler argues that convergence is coming and that it's not the mirrors that matter. Read more

Panasonic 4K Photo reaches to grab stills-from-video dream

Using a video feed to capture stills isn't a new idea - Nikon's first electronic camera, the QV-1000C, did it in the late 1980s - but the resolution of 4K makes it more useful. Panasonic has recognized this way of working and has introduced 4K Photo mode to its 4K cameras, to make things easier for the user. We took the feature for a test drive. Read more

Columbia University researchers create self-powered video camera

Columbia University researchers have created a self-powered video camera featuring a sensor that both captures images and powers the device. Although it can only record low-resolution 30x40 pixel images at 1fps, the photodiodes on the camera's sensor can switch between being photoconductive, and photovoltaic. In the latter mode - given enough light - the photodiodes supply enough power to a built-in supercapacitor to keep the camera operating indefinitely. Click through for more information

Flat elements developed by Harvard could make camera lenses smaller, lighter and better

A team at Harvard School of Engineering has developed a method for making flat lenses that could dramatically reduce the size and weight of camera lenses in the future. The method employs tiny silicon antennas positioned on flat glass components to redirect light when it reaches the surface of the lens instead of relying on refraction and the thickness of glass to bend light in a particular direction. Learn more
