I liebäugle long with a successor to my DMC FZ10 (the first of the Panasonic LUMIX series, then through already with 2.8 intensity!), So I have been following the reports of the FZ50, FZ200, FZ1000 etc. very precisely. The joy was great when I heard, the DMC-FZ1000 should have a 1 inch sensor (ie 25.4mm). The is not so! The dimensions of the sensor be 8,8mm 13,2mm times. Therefore, results after Adam Riese a sensor diagonal of 15.8mm. This is far from 25.4mm. How can this happen? Well, you told me so: Once Upon a Time in the time of image capture tube. There each picture tube had a glass outer diameter and an associated light-sensitive surface. If the outer diameter was one inch (25.4mm), the light-sensitive surface was about this size. That is: It is said that the sensor possess 25.4mm diagonal, but in truth he has only 15.8mm. This is Marketinggewäsch and disappointed when investigating after a usable digital camera. Everyone knows that the sensor size is the decisive factor for the sharpness and resolution.
