Pentax *ist DL2 Digital SLR - Test Shots - Full Resolution Crops
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.
1/250th sec, F8, ISO200
At the lowest ISO setting the ist DL2 produces nice smooth noise-free images, although the red is a bit over-saturated.
1/350th sec, F8, ISO400
At 400 ISO there is still no image noise, although contrast seems to have been slightly increased.
1/500th sec, F9.5, ISO800
At 800 ISO there is the faintest hint of noise in some mid-tone areas, but the image is still very sharp with good detail.
1/1000th sec, F9.5, ISO1600
At 1600 ISO there is image noise visible over most of the image, but none of the red-green random speckling normally seen at this speed.
1/2000th sec, F11, ISO3200
At 3200 ISO there is a good deal of image noise, and colour speckling is clearly visible all over the image.
