Hi. This is a suggestion for a topic that I think would be VERY interesting to a lot of SC readers: Truth about sensor size. A LONG time ago dpreview had an article explaining that a sensor size listed as 1/2.3" for example on a compact camera is NOT anywhere near a half an inch but is based on an ancient standard for video tubes. But David Pogue had a recent article where he contradicted that and said that the sensor size is just what you'd guess -- 1/2.3" means 1/2.3" diagonal measure. A new website Sensor-Size: Compare & Convert Digital Cameras keyed off of Pogue. Was dpreview wrong? We're not talking about a minor quibble. We're talking about a difference that can be a factor of 10x in sensor area! Here's the old dpreview article: Making (some) sense out of sensor sizes: Digital Photography Review EXAMPLE: 1/1.8" - actually a pretty decent sensor qualifying for serious compact status - has a diagonal of less than 9mm. If dpreview was right, this has to be one of the biggest SC misconceptions out there.
