See my Micro 4/3 wish list at B&H Photo.
This page compares technical image quality of the Olympus OMD E-M1 Mark II from a 20-megapixel raw file to a 50-megapixel downsampled hi-res mode JPEG, downsampled to match the 20-megapixel raw file. While it is much preferable to compare raw to raw, Photoshop did not yet support Hi-Res ORF files at the time this page was prepared.
The Olympus OMD E-M1 Mark II delivers 50 megapixel JPEGs when shot in its Hi-Res sensor shift mode, producing three files simultaneously from its 20-megapixel sensor:
- 49.9-megapixel JPEG file (8160 X 6120)
- 20.1-megapixel ORI file (5184 X 3888)
- 80.6-megapixel ORF file (10368 X 7776)
The huge ORF file has nowhere near the detail its 80 megapixels imply, so the question is how much it really offers over the standard resolution file. The Olympus position is that it offers up to about 50 megapixels of detail under ideal conditions; hence the 50MP JPEG that is output. Indeed, the file quality is high at that size, but fine detail is much less than the 50MP figure implies.
Includes images up to 40-megapixels (the sensor is 20 megapixels).
I eked this post out finishing it 20 minutes before a minor surgery, hopefully I will be able to do more but involves a hand so I may be out a few days.
