|Color range of the Olympus Mju 9000
The color range, expressed in bits, shows that the Olympus Mju 9000 performs optimally to good from 64 to 800 ISO. With an average of 21.12 bits (over the entire ISO range) out of 24 bits, the Mju 9000 is able to reproduce fairly accurate, true-to-nature colors especially at the low ISO values. The auto white balance did not encounter much trouble to filter color casts effectively.
ISO sensitivity of the Mju 9000
According to the specifications, the Olympus Mju 9000 features an increasing sensitivity range from 64 to 1600 ISO. The actual ISO sensitivity of the image sensor does deviate at times. From technical DIWA measurements it shows that ISO 64 to 400 measured an average deviation of about 13% at lower ISO and 6% at higher ISO. These are decent figures while an average deviation of 20-25% is quite common. The higher ISOs of 800 and 1600 ISO deviate with an average of 31.5% with a lower value than specified. This is something to keep in the back of your head and it certainly won't hurt to use the exposure compensation.
Signal / noise ratio
The sample pictures already hinted at it, and now the technical measurements make it all too clear; the Olympus Mju 9000 faces a lot of trouble keeping the signal/noise ratio at an acceptable quality level, which avenges in practice. Even from ISO 200, every nerve has to be strained to avoid noise, and that shows through a loss of detail in a picture. At high ISO settings, noise is inevitable and that is a huge disappointment. Especially when you want to shoot sequentially at a faster speed without using the flash (considerable charging times) and, for example, at ISO 800.
|As an Olympus Mju 9000 owner, you will have to accept visible noise. It is a typical example of the disadvantage of large numbers of pixels on a small image sensor. If a similar sensor with 8 Megapixels had been applied to the Mju 9000, the result would have undoubtedly been better. Unfortunately, however, the marketing departments use the argument that consumers want these amounts of Megapixels...
Olympus Mju 9000 lens quality
Because of the 10x optical zoom lens, the Olympus Mju9000 belongs to the average compact mega zoom cameras. Canon and Panasonic are leading this segment with their 12x optical wide-angle zoom. Integrating such a large zoom range in a compact body is truly an achievement. It is not easy to keep the 28-280mm range at a high-quality level. After the tests in practice and in the lab, it becomes clear that the lens finds it difficult to prevent blur on the edges. In wide-angle, blur is visible although telephoto is even worse with significant blur of the edges. If we compare this result to the lens of the Panasonic Lumix TZ7, we come to the conclusion that Panasonic achieves remarkably better results.
Distortion and chromatic aberration
When it comes to distortion, the Olympus Mju 9000 is in control. As expected, the 28mm suffers from distortion however; it is still acceptable and does not actually show in practice. The other focal lengths have virtually no distortion at all. Chromatic aberration does not play a real role for this lens. Only in maximum telephoto mode, we find some purple fringing, but this can be corrected afterwards if it really bothers you.
