For all those of you interested in MicroFourThirds the new Panasonic sensor (used for the new Panasonic LX5
According to Panasonic the sensor has a new design which allows to capture more light for every single pixel. Quesabesde also noticed a better chromatic noise control (but this maybe depends form the new Venus engine). You can judge the difference between the LX3 and the LX5 sensor by looking at those images: http://www.quesabesde.com/camdig/noticias/Lumix_LX5_muestra_02g.jpg. Panasonic itself claims that the new sensor is noiseless at ISO 800 which (if true) is a very good news considering that the sensor has a much higher pixel density than current MicroFourThirds sensor. Panasonic also said that the LX5 sensor has a better sensivity (by 31%) and saturation (38%) and greater dynamic range compared to the older Panasonic LX3.
