Micro Four Third+<br />Concept for a branching from the Micro Four Third standard mount specification.<br />
Background<br />Micro Four Third specification:<br />Sensor size: 17,3 x 13,0 mm<br />Width 1,365x smaller than Nikon’s APS-C (23,6 x 15,6mm)<br />Flange distance: 20mm<br />Thread diameter: 38mm<br />Common criticism:<br />Relatively smaller sensor<br />Inherently lower dynamic range<br />Larger depth of field<br />
Idea<br />There is large area wasted on the inner side of the mount compared to sensor size (red).<br />The space inside the mount can actually fits APS-C sized sensor.<br />This will also utilize larger part of legacy lens image circle.<br />
Problem<br />Electronic contacts are located too close to the centre.<br />This will get in the way of the image sensor.<br />Electronic contacts have to be compatible with the specification for backward compatibility with lens designed for the original mount standard.<br />Tight placing inside the mount might mean there will be vignetting near the corners.<br />No warranty legacy lens image circle would actually cover the whole sensor<br />
Idea<br />Fit in larger image sensor.<br />Flange distance stays the same.<br />Contacts shifted downward out of the way.<br />The camera is supplied with adapter to reroute the contacts.<br />The adapter will cover part of the image sensor.<br /> Automatic algorithm to crop the image automatically and minimize vignette when using the original lenses (smaller image circle)<br />Lower megapixel utilized.<br />Also works for C-Mount lenses.<br />
Implication<br />This will branch away from the original Micro Four Third standard.<br /><ul><li>Sensor proportion will stay the same.
