Noise, resolution and sensitivity
These images show 72ppi (100% on a computer screen) sections of images of a resolution chart, captured using the Samsung 85mm f/1.4 lens. We show the section of the resolution chart where the camera starts to fail to reproduce the lines separately. The higher the number visible in these images, the better the camera’s detail resolution at the specified sensitivity setting.
With the same 20.3-million-pixel sensor that Samsung used in the NX200, the image resolution of the NX210 is on a par with its predecessor. A lot of detail can be resolved at the lowest ISO 100 sensitivity, although at all sensitivities JPEG files do appear to be a little soft.
What is interesting is that we conducted our resolution chart test with both the 18-55mm kit lens and the 85mm lens, and while the 85mm optic is slightly better, it is not significantly so if JPEG images are all that are ever shot. Far more detail, particularly textures, can be revealed by shooting SRW raw images, and it is here that the 85mm is the superior lens.
Although noise isn’t visible in JPEG images until the highest ISO settings are reached, the effects of noise reduction are visible even at ISO 400. Close inspection shows that images look smudged and devoid of detail. It is a shame because the sensor has a lot of potential, but, JPEG compression and noise reduction is a bit harsh.
Overall, I would say the image quality is the same as we have seen from the other Samsung cameras with this sensor, and to really see the full potential of the sensor it is best to shoot raw to maximise resolution, sharpness and noise reduction.
