Note: These ISO test shots were taken indoors using two domestic 60W tungsten bulbs as the only light source, with the camera’s white balance set on automatic. The camera was mounted on a tripod, and the self-timer was used to prevent shake.

½ sec, F4.5, ISO 50. At the lowest sensitivity setting the picture is smooth and crisp with excellent colour rendition and no visible image noise despite the long shutter time.

¼ sec, F4.5, ISO 100. At 100 ISO image quality is still extremely good, with no visible noise, although there is a hint of colour speckling in the mid-tone areas.

1/8 sec, F4.5, ISO 200. At 200 ISO there is a little noise beginning to break through in the darker areas, although it is very even and has little effect on overall quality.

1/5 sec, F4.5, ISO 400. At the highest ISO setting the image noise and colour speckling are more pronounced, but are well controlled and the image is still usable.
