With many of the same specifications as the D5300, but with an added vari-angle touchscreen and a tweaked body design, is the Nikon D5500 really offering enough to stand out from its predecessor?
Nikon D5500 Review – Image Quality: Detail and Noise
The D5500’s JPEG images at lower ISO sensitivities of ISO 100-400 are superb, as the in-camera processing reduces the small amount of noise present in the raw images without sacrificing much of the detail. It’s only at ISO 800 that I started to notice obvious luminance noise, mostly localized in the shadow areas; but looking really closely, low contrast detail starts to disappear too. However the camera continues to give entirely usable files up to ISO 3200, and it’s not until ISO 6400 that processing starts to become quite aggressive, and detail starts to breakdown seriously. The highest settings are, as usual, both really only for use when absolutely necessary, with ISO 25600 in particular giving large amounts of chroma noise and little in the way of fine detail.
