Chris joins us to talk about sensor size in digital cameras. Is bigger better? Chris says that "full frame" sensors are the size of a frame of 35mm film. Digital sensors that size are expensive. Smaller sensors are far more cost effective for budget filmmakers. You pay a price with smaller pixels in that you get more noise in low light as camera makers stuff more pixels on smaller sensors, but smaller sensors have the advantage of making telephoto length appear larger. A 200mm lens on a full frame is just 200mm. On an APS-C, it could be a 300mm focal length. Conversely, full frame cameras do better with wider angles.
Don't forget our current assignment ... RESOLUTION. Take a picture and upload it to Flickr, tagged with the Tech Guy Group and "resolution." You have one more week and we'll review them. So get your images in!
