There’s probably more talk about sensors in digital photography than anything else, so here’s a run-down on sensor basics and everything you need to know to make sense of the jargon. First of all, sensors are made using two types of chip technology. They’re often used in sensor descriptions so it makes sense to mention […]

A newer type of sensor where the circuitry has been moved to the back so that the light receptors on the front are unobstructed. This gives a modest but useful improvement in light-gathering power, digital noise and overall image quality, but it’s not the dramatic technical leap that manufacturers often suggest.
