Compared to...

Below you will find a studio comparison between the Kodak DX7590 and the only other 5MP super zoom camera, the Panasonic Lumix DMC-FZ20. We have included samples for the lowest and highest ISO settings for each camera (80 and 400).

Studio scene comparison (@ ISO 80)

  • Kodak DX7590 : Aperture Priority mode, ISO 80, Default Image Parameters,
    Manual white balance (daylight), +2.0 EV compensation
     
  • Panasonic DMC-FZ20: Aperture Priority mode, ISO 80, Default Image Parameters,
    Manual white balance
     
  • Lighting: Two 800W studio lamps with dichroic daylight filters bounced off the ceiling

Despite similarities in the color and tonal range between the two cameras (note that the slight color differences are white balance-related) there are important differences when you start to look a little closer. Most importantly it is obvious that the Kodak's Schneider lens is not capturing anything like the level of fine detail you get from the Panasonic's Leica zoom. There is a definite fall-off in sharpness towards the edge of the frame, though this is not very visible in many real world shots. Noise is low in the Kodak image, but this is down to much more heavy-handed noise reduction, which will have caused some of the loss of very fine detail. The results are pleasing, the colors warm but fairly accurate and the smoothness admirable, but there's just a lack of biting sharpness.

It is also worth noting that in this studio situation we found the DX7950's metering to be quite unreliable (notice that we needed an unprecedented +2.0 EV exposure compensation to get the right exposure). This can partly be explained by the white background, but we rarely need to apply such extreme AE compensations in the studio.
