Olympus E-5 Camera review | Adjustments
In addition to the test in practice, the Olympus E-5 is also extensively tested in our DIWA Lab. DIWA Labs tests the image quality of the Olympus E5 in an up-to-date laboratory environment that is equipped with the DxO Analyzer (version 3) which is the most advanced software to test the image quality of cameras. Testing this image quality is a complicated and time-consuming matter. Artifacts in the optical design, imperfections of the image sensor and shortcomings of the image processing algorithms are important factors that play a role in delivering high quality pictures. Today, it is an almost impossible task to evaluate pictures with the naked eye, especially with current technologies and tiny differences in the results.

Olympus E-5 color reproduction
The Olympus E-5 is a typical photographer’s-DSLR, which is evident from the extensive setting possibilities with which the photographer’s demands are almost always met. You can adjust the camera completely according to your own wishes and go beyond the basic settings. That is the case for the color reproduction that we measured precisely in the DIWA Labs. The color reproduction seems to be very accurate compared to the Gretag Macbeth Colorchecker. There is no exaggerated color saturation anywhere; the camera achieves a fairly ‘authentic’ color. Whoever wants to apply extra saturation in certain color channels, can live it up in the camera’s menu.

Olympus E-5 white balance
Performance in terms of white balance is also included in the technical test procedure. The automatic white balance has the tendency to deliver a bit warmer tones with artificial light, but generally the results are very satisfactory. The Olympus E-5 performs optimally when we apply the manual white balance. There is practically no color haze and a very accurate white balance across the entire ISO range.

Olympus E5 signal / noise ratio
In comparison with its predecessor, the Olympus E-5 has greatly improved the signal/noise ratio. Up to 1600 ISO, the camera produces images with little noise, which clearly increases the playing-field of the ISO values in comparison with the E-3. Only from 3200 ISO is noise inevitably visible in the image. That is a fine achievement and will mean that the photographers switching from an E-3 will have extra room to play with lighting. That is definitely a bonus.

Olympus E-5 image stabilisation
The Olympus E-5 is equipped with a vibrating sensor that compensates camera shake. The advantage of image stabilization in the sensor is that it works for every lens; you don’t have to acquire any special lenses.

Olympus camera review
The image stabilization in the Olympus E-5 works well; up to 3-4 stops is not a problem. I do have to warn you that it is not a miracle cure. Not all movement can be eliminated by the stabilization, and sometimes you will have to use the tripod, which is actually always the best solution if you want a perfectly sharp image. This is, of course, not very practical.

Olympus E-5 dynamic range
The dynamic range has also improved. A fantastic dynamic range is possible especially at low ISOs up to 800. Maintaining a significant amount of detail in the darker and lighter parts of an image contributes directly to the general quality experience. What you would like to prevent as a photographer are heavily condensed shadows or faded-out light parts. From 3200 ISO, but more at 6400 ISO, this chance increases. This also gives you more room to play with different types of lighting in different situations as a photographer.

Olympus Zuiko 12-60mm lens
For testing I had the new Zuiko Digital ED 12-60mm 1:2.8-4.0 SWD at my disposal. A beautiful compact lens with a relatively large opening. The range also appeals to me; compared with a 35mm camera it offers 24-120mm that will let you capture nearly everything. I can't say it often enough that this is the biggest advantage of the FourThirds System; compact light sensitive lenses with a large range. The lens is weatherproof so it makes a perfect combination with the Olympus E-5. Also the performance of the lens is on a level with the camera. Of course we see some barrel distortion in maximum wide angle but it quickly changes to an almost neutral mode. Just a tiny bit of barrel distortion remains. The sharpness is fine over the entire range except for when you reach the maximum aperture. If you go further then f/11 the sharpness decreases. Next diffraction turns up but then again every lens suffers from it. Chromatic aberration is fine and vignetting decreases as soon as you change the aperture one stop.
