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.
1/3rd, f/2.8, ISO 80
At 80 ISO the image is clean and noise free, as one might expect. Make the most of it, because it won’t last.
1/4th, f/2.8, ISO 100
Just 1/3rd of a stop faster at 100 ISO and already there is a hint of image noise visible in this shot.
1/8th, f/2.8, ISO 200
At only 200 ISO there is visible image noise and colour speckling in the mid-tone and darker areas of this shot. A surprisingly poor performance from the usually unassailable Canon.
1/15th, f/2.8, ISO 400
At 400 ISO the image noise has wiped out a lot of fine detail and reduced picture quality to almost unusable levels.
1/30th, f/2.8, ISO 800
At 800 ISO the image is covered in very severe noise and colour distortion. Fine detail has been utterly lost in the haze and the picture is unusable.
