At the minimum sensitivity setting of 50 ISO there is very little image noise, although there is some speckling in the darker areas

/5fb5c0|d450_1325-iso100.jpg
Not much difference here at 100 ISO, still very little noise but the shadow areas have some spots

/a65617|303b_1325-iso200.jpg
At 200 ISO some colour noise is starting to creep into the dark areas, such as the mudguard and tyres, but it still not excessive

At the maximum 400 ISO setting there is quite a bit of noise all over the picture, but it is still fairly well controlled and not excessive
