This camera breaks the laws of physics

Published in Technology

Hot on the heels of Nokia's 808 PureView, a smartphone with an over-endowed 41 MegaPixel sensor that allows smooth, lossless digital zooming, comes the Sony NEX-EA50EH. It's definitely not a phone, but does share one fascinating feature in common

Making sense of Sensors - part 2

Published in Technology

As we saw in my previous article on sensor technology, we can now build sensors with enormous numbers attached to them - if not trivially, at least reliably. Given that current 4K sensors are more than adequate to replace 35mm film in terms of sheer resolution, we need to be careful about turning this into a numbers game.

Last time, we discussed some of the technical concerns of lens selection and the issues of compatibility with sensors of various configurations and sizes. In this part, we'll look at the effects sensor size has on photography and the engineering compromises behind lenses and sensors

When cameras are Good Enough

Have cameras reached the point where we need to be looking beyond resolution to judge their film-making abilities?

The NEX-EA50EH is an NXCAM Camcorder with a large format Exmor APS-C HD CMOS sensor and interchangeable E-Mount lens system that can shoot in full HD and take 16 megapixel still photos. It comes with the newly developed SEL-P18200 18-200mm Power Zoom E-mount lens with “Optical Steady Shot” image stabilisation

Most large-sensor cameras use a Bayer colour filter pattern to allow full colour images to be output - after "debayering". This entire process is now pretty routine but unfortunately what is also routine is the amount of light lost through the colour filter process. Less light means more noise, and noise is what ultimately limits the low-light capabilities all cameras
