|Upon arrival of a Panasonic LUMIX FX150 test sample, it is tested in our DIWA Lab. The technical data of the rigorous tests are processed and translated into understandable data. Inside the lab, testing takes place in standardized circumstances. An environment in which cameras, both compact and system concepts can be compared without a problem. Besides that, the Panasonic FX150 camera is extensively used in practice and evaluated as for operation and shooting in practice. This combination of lab tests and the testing in practice, results in a final conclusion that is carefully reviewed.|
|Accurate color reproduction & white balance
During testing in the DIWA Lab, the color reproduction of the Panasonic LUMIX FX150 is also tested, among other things. The Gretag Macbeth Color Checker is used as reference. From the tests, it turns out that the Panasonic FX150 camera delivers quite an accurate color reproduction up to and including ISO 400 and at higher ISO shows a small difference. This difference is measurable in the lab, however in practice it is hardly visible by the naked eye. The camera is also very well able to set a precise white balance, although the optimal results are obtained when setting a manual balance. In this mode, up to and including ISO 800 an excellent result is obtained, after that it becomes somewhat inaccurate. The auto white balance is sensitive to an excess of incandescent light, yet the manual setting overcomes this problem.
Sensor sensitivity deviation
The ISO values of the Panasonic FX150 specifications are on par with the actual sensor sensitivity. It is not unusual to find a deviation of 20-25%, yet the Panasonic LUMIX FX150 shows quite a regular value of an average of 9.5% more sensitive at 200-1600 ISO, at which 100 ISO is still within margins with a 13% lower value. Higher ISOs show the annoying noise, in measurements and practice, that takes the image quality down. The AUTO ISO setting at which a maximum ISO can be decided, comes in handy here.
|Dynamic range of the Panasonic FX150
The dynamic range is almost similar to the signal/noise ratio of 100-400 ISO. From a quality viewpoint. At ISO 400 we see the ability to reproduce details in dark and light areas without both areas becoming slurred. Somewhat disappointing is the fact that the camera has troubles reaching the same result with 400 ISO as it does with 100-200 ISO. If we compare the results with, for example the Panasonic LUMIX LX3, a 10 Megapixel model, we can see that the latter with this ISO range gets more out of it when it comes to dynamic range.
LEICA DC-VARIO-ELMARIT lens
Whilst measuring the sharpness of the LEICA DC-VARIO-ELMARIT f/2.8-5.6 ASPH lens, the zoom lens turned out to perform excellently. The centre focal length shows hardly any blur towards the edges. Furthermore, the 3.6x zoom lens delivers excellent sharpness. Distortion in general is fine, only the centre of the 28 mm wide angle shows visible distortion, however, this is not unexpected. The remaining focal lengths are excellent.
Chromatic aberration & vignetting
One thing the wide angle of the LEICA lens suffers from is chromatic aberration. The purple edges are visible in the entire aperture range around objects with high contrasts. That brings us to the results of vignetting. The zoom lens of the Panasonic LUMIX FX150 withstood the tests excellently and the lens is free from any visible vignetting. All in all, the 3.6x zoom lens did very well and is a precious addition to this camera.
