Olympus E-3 Studio resolution / JPEG and RAW results
|
 |
|
To measure and compare the Olympus E-3's resolving power we photographed the Enhanced Digital Camera
Resolution Chart with it and a number of rival models, each using their
best quality JPEG and default image tone and sharpening settings. We tested the Olympus E-3 using the Zuiko Digital 12-60mm SWD lens at all apertures and selected the sharpest result.
The crops are taken from the original images, saved as High Quality JPEGs
in Photoshop CS2 and presented here at 100%. Each number represents 100
lines per picture height (lpph), so a figure of 20 means a resolution of
2000 lpph. |
Fitted with the Zuiko Digital 12-60mm SWD lens at f8, the Olympus E-3 resolved 2200 lpph of horizontal and vertical resolution. This places it comfortably above the Canon EOS 40D and close to the Nikon D300 and Sony A700 results.
Note the E-3 does has a slight advantage in this test though thanks to its narrower 4:3 aspect ratio resulting in a slightly higher vertical resolution than traditional 10 Megapixel cameras which spread their resolution over a wider 3:2 aspect ratio. This is one of the reasons we're not surprised to see it out-perform the EOS 40D when both are capturing the same vertical picture height, but even with that taken into consideration, 2200 lpph is still a good result for the E-3.
With the quality 12-60mm SWD lens, it edges ahead of the 10 Megapixel E-510 and delivers a result close to higher resolution 12 Megapixel models. While the D300 and A700 are resolving greater detail in this studio test, it's not a great deal more and doesn't make a big difference in real-life situations. Certainly while 10 Megapixels sounds relatively modest for a semi-pro model, the E-3 can essentially keep up with its current rivals. The big question is what resolution will Olympus implement in the future with the smaller Four Thirds sensor, but for now the E-3 has nothing to worry about in the resolution department.

Olympus E-3 Studio resolution: JPEG versus RAW
We photographed the test chart in the E-3's RAW plus Large Fine JPEG mode, allowing us to directly compare images created from exactly the same data. Below are crops taken from the original JPEG file alongside the RAW version, processed in Adobe Camera RAW using the default settings, saved as a 16-bit TIFF, then opened in Photoshop.
As seen on the previous page, Adobe's RAW conversion has taken a slightly different approach to tone and sharpening, with a slightly softer result that resolves fractionally less ultimate detail. As always though, the benefit of shooting in RAW is being able to further tweak the settings and apply more sophisticated processing, but as seen here and throughout our review, the E-3 can certainly produce some very pleasing images using its in-camera JPEG processing and default settings.
Now let's check out the camera's performance at different sensitivities in our Olympus E-3 noise results page.
