Sony Alpha A700 Digital SLR - Test shots - ISO performance
Over the next few pages we show a range of test shots. On this page the full size image at the minimum and maximum ISO settings have been reduced to let you see the full image, and a series of full resolution crops have taken from original images at a range of ISO settings to show the overall image quality.
This is the full frame at 100 ISO. The A700 has a manual ISO setting range of 100-6400 in 1/3EV steps. I've only shown the full-stop settings here for brevity.
On a 13-second exposure at f/16 and 100 ISO. The slight motion blur is actually caused by the organ itself vibrating.
6 secs at f/16 and 200 ISO, and still no image noise.
3.2 seconds at f/16 and 400ISO. The music had stopped at this point, so the picture is a bit sharper. Still no image noise.
1.6 seconds at f/16, 800 ISO. Still no visible noise at this setting.
0.8 sec, f/16, 1600 ISO. There is a faint trace of colour speckling creeping in at this setting, but the image quality is still very high.
0.4 sec, f/16, 3200 ISO. There is a little more noise, but you could still get a good A4 print off this.
1/5th sec, f/16, 6400 ISO. There is significant noise at this setting, and colour rendition has suffered accordingly, but it is still just about usable.
This is the full frame at 6400 ISO.
