A range of test shots are shown over the next three pages. Here, the full size image has been reduced for bandwidth purposes, and a crop taken from the original full resolution image has been placed below it in order for you to gain an appreciation of the overall quality. The following pages consist of resized images so that you can evaluate the overall exposure. For those with a dial-up connection, please be patient while the pages download.
Note: The EOS 30D has 14 ISO settings between 100 and 3200. However under normal use only 100-1600 are used, and to save space we’ve only shown a representative sample here. The shots were taken in natural ambient light using default settings and program exposure mode. Light levels rose and fell between shots due to the weather.
1/60th, F4.5, ISO 100
At the lowest ISO setting the picture is completely noise-free and smooth as polished marble.
1/80th, F5.6, ISO 200
At 200 ISO there is no noticeable difference between this and the previous shot.
1/100th, F6.3, ISO 400
At 400 ISO there is a hint of image noise beginning to appear in the shadow areas, but the majority of the image is still sharp and smooth.
1/200th, F9, ISO 800
At 800 ISO the same levels of noise have now spread to the mid-tone areas as well, but on the whole the image is still very good, and quite printable.
1/200th, F9, ISO 1600
At 1600 ISO the shot is, surprisingly, almost identical to the 800 ISO sample. In fact I had to check the EXIF data to make sure I had the right shot. Impressive.
