Sharp today announced the six megapixel, 1/1.8" type RJ21T3AAPT/ST CCD. This new sensor is exactly the same size (type) as used in many current four and five megapixel digital cameras and so will be an attractive option for digital camera manufacturer as an easy way to launch 'new' models with more megapixels (it's sad but people are still buying the numbers game). Once more this raises the question of noise and lens quality, how much noisier (if it all) will this sensor be and will the current lenses (some of which were designed for three megapixel 1/1.8 CCD's) be able to deliver enough resolution to deliver any real gain (other than file size). This new sensor has a pixel pitch of just 2.5 µm, the smallest yet.
