Olympus OM-D E-M5 Samples
Olympus OM-D E-M5 Comparative Crops
The Olympus OM-D E-M5 is known to deliver the very best image quality from a Micro Four-Thirds digital camera to date. To evaluate the advantage of sensor-size with current technology, here we compare it to state-of-the-art 16 megapixels APS-C and Full-Frame sensors from the Pentax K-5
Pentax K-5 and the Nikon D4
Nikon D4 respectively.
| Olympus OM-D E-M5 | Pentax K-5 | Nikon D4 |
|---|---|---|
| ISO 200 | ISO 200 | ISO 200 |
| ISO 400 | ISO 400 | ISO 400 |
| ISO 800 | ISO 800 | ISO 800 |
| ISO 1600 | ISO 1600 | ISO 1600 |
| ISO 3200 | ISO 3200 | ISO 3200 |
| ISO 6400 | ISO 6400 | ISO 6400 |
| ISO 12800 | ISO 12800 | ISO 12800 |
| ISO 25600 | ISO 25600 | ISO 25600 |
Even though noise-reduction is turned off on all these cameras, they each takes a different approach to image processing which is why the crops look so different. However, it is clear that the gap between Micro-Four Thirds and APS-C is much smaller than between APS-C and Full-Frame. This makes sense since the surface area of an APS-C sensor is closer to Four-Thirds than to Full-Frame.
APS-C currently shows a visible lead over Micro Four-Thirds from ISO 400 to 6400, while Full-Frame leads from ISO 400 to 25600 and beyond. The comparison stops at 25600 because that is the maximum sensitivity of the OM-D E-M5.
