View All

A range of test shots are shown over the next few 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.


1/25th, f/3.3, ISO 64

At the lowest sensitivity setting the picture is smooth and noise free, but the lousy weather means a dull low-contrast picture.


1/40th, f/3.3, ISO 100

At 100 ISO the picture is still smooth and free of image noise.


1/80th, f/3.3, ISO 200

Up one stop to 200 ISO and the picture is still very good, although there is a hint of colour distortion creeping in, with green and red splotches.


1/160th, f/3.3, ISO 400

At 400 ISO there is definitely some image noise visible, but the overall image quality is still good and the picture would print well.


1/250th, f/3.3, ISO 800

At 800 ISO the image noise is more severe and coarse-grained, and would show up on even a small print, although colour and contrast are still good.


1/100th, f/6.6, ISO 1600

At the maximum 1600 ISO the image noise is now very bad and the image quality is seriously degraded, with reduced contrast and colour saturation.
