This sensor sees everything

Published in Technology & Computing

Imagine Google Earth or Google Maps represented not as a still image, but as a full-motion video, showing the positions of cars, people and even birds in real time

The ENG-style camera with the heart of a DSLR

Published in Production

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

Are big sensors always best?

Published in Technology & Computing

Internet forums, YouTube and magazines are full of articles extolling the virtues of large sensor video cameras, whether it's the Red Epic or the Canon C300. But should we be obsessed with the Big Chips, or do they have a downside as well. Kieron Seth investigates.

Epic killed by laser!

Don't take your expensive camera to a laser show!

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

Bryce Bayer's incredible foresight

Published in Technology & Computing

Somehow, I managed to overlook the fact that last month saw the death of Bryce E. Bayer, the man who decided that the best way to make a single-chip colour imaging sensor was to silk-screen a pattern of coloured filters on the front

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

Published in Technology & Computing

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

Making sense of Sensors - part 2

Published in Technology & Computing

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.

Vintage lenses for large-sensor cameras - Part 1

Published in Production

Here's another chance to read this meticulously detailed feature, where Uli Plank shows us how to look for lenses up to 50 years old, and use them with our modern, large-sensor cameras.
