Went to a viewing of the OMD EM1 tonight. The rep explained what the new sensor can do. 1. Sharpening on selected focal plane only. What this means is if you were to shoot a portrait and the background is to be out of focus the sensor reads this information from the settings being used and will only sharpen the image on the sensor plane of focus. It does not sharpen the whole image. This creates a smoother out of focus area (no artefacts) - this setting emulates a more film look image. 2. Automatic correction of CA This is for olympus lenses only. Information for each lens is programmed into the camera. 3. Diffraction Correction This new sensor corrects for diffraction so that you can now use your lens at f22 and the camera will correct for diffraction on the focused focal plane. HOWEVER ---- To be able to access all those lovely new features you must load your images into the Olympus software. Asked about being able to get 1/8000 and ISO 100 with the OMD EM5 in a new firmware upgrade (hoping they might offer one) He advised that ISO 100 may be possible but that 1/8000 is not as it is a different shutter mechanism (shattered my hopes).
