What are the advantages of the sensors 4:3 aspect ratio?
In the real world of printing images, the traditional 3:2 aspect of 35mm film and APS sensors has resulted in lost information when printing to the standard non-consumer print sizes of 8″ x 10″, 11″ x 14″ and so on. Only consumer 4″ x 6″ prints neatly fit the 3:2 aspect ratio. The 4:3 aspect ratio of the E-1’s Full Frame Transfer CCD allows photographers to fit their image easily into the standard print sizes used by professionals and press, thereby avoiding cropping. This means they can use the image as they composed it in the viewfinder without any loss of image quality.
