Well, this is interesting. It seems that Olympus (AKA OM Digital) might be looking towards the stars. A new Japanese patent describes a new Micro Four Thirds system with a built-in “astrotracer” feature. Essentially they want the sensor to track the motion of the stars so that you can get longer exposures at night without getting blur from the planet’s rotation.
It’s a nifty sounding feature and it’s one we’ve actually seen before, although it’s perhaps not surprising that most people have never heard of it, as it was found in the Pentax K1 Mark II, amongst others. They both appear to work in a similar way, too, with the sensor moving to compensate for the earth’s rotation and keep the stars in the same part of the sensor.
