Though with a rating of 6.6 out of 10, the FX55 fares well in some aspects of image quality- its exposure, white balance, and color are impressive.
The camera’s image quality falls apart when it comes to noise. I saw noise even at the lowest sensitivity setting of ISO 100. At ISO 200, Panasonic was already engaging a noticeable blur filter to keep noise from getting out of control, though at the expense of sharpness, which means a loss of fine detail. At ISO 400 noise increases more and more detail is lost, though there is still a decent amount of shadow detail present and you should be able to get acceptable prints. Noise increases precipitously at ISO 800, with even more loss of fine and shadow detail and finally plummets off the deep end at ISO 1,600. I recommend staying below ISO 800 when shooting with the Panasonic Lumix DMC-FX55.
