The camera menu was also modified. Firstly, there appeared a histogram, which can be displayed in camera mode as well as in the playback mode, and the ISO sensitivity range is changed. The new camera offers 50, 100 and 200 ISO.













CCD area remained the same, while the number of pixels is increased from 5 to 6 Mp. You will hardly notice the difference on 10x15 or 13x18 photos, especially considering that, as in the previous model, the spreading determined by lens adjustment is quite considerable among different cameras of the same consignment. That is we can easily find a 5Mp camera with a better resolution than 6Mp, and vice versa. Anyway, all cameras meet the requirements set to digital point-and-shoot cameras.

Sensor area change is about 15%. So one can assume that the previous model had its real sensitivity a tad overestimated. If you compare it to large 6Mp matrices, 20x15 mm in reflex cameras, you will notice practically no differences with sufficient illumination. If the illumination is not enough, the 9 times as small sensor area will immediately has its effect. As you can see in the table below, the same noise level in a larger matrix is demonstrated at 400 ISO. These figures may vary depending on the illumination spectrum. However, there is nothing to be done, the noise level is in inverse proportion to the sensor area.

To my mind, the default settings provide excessive contrast and brightness, which highlight defects instead of enhancing the image. The cameras I tested provided better results when I set contrast and sharpness to minimum in the menu.
