I for many years with Olympus SLR - cameras, and at least since the digital age with the modern Olympus -'m cameras go, I think knowing how I evaluate the system: In apparent arguments as "the sensor is small" or "noise in higher ISO range", I will here not go only in detail. These are pushed forward things that are not durable to degrade the system what it deserves in any case. To take a picture, we absolutely need light, and this light is only supposedly due to high ISO - replacing numbers. The Four Thirds - System is designed in conjunction with the accompanying new lenses specifically to each other, has been constructed separately. Quality and robustness in the processing and appearance of the E-5 are unique. Reliability leaves no room for criticism. The quality of images in JPG "out of Cam" is almost unbeatable. The performance of the system I find totally decided. Service of Olympus with questions / repair very satisfactory. Anyone have an E-5, also used, can now get hold of, it should do so ....
