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.
¼, f/4.9, 100 ISO
At the lowest ISO setting the image quality is predictably flawless, with not a trace of image noise, although the shot is under-exposed by about half a stop.
¼, f/4.9, 200 ISO
This time the exposure is spot on, and the picture is still totally noise free.
1/9th, f/4.9, 400 ISO
At 400 ISO most cameras are showing significant image noise, but with the F31fd this shot is virtually identical to the previous one.
1/18th, f/4.9, 800 ISO
At 800 ISO there is still virtually no visible image noise, although the noise reduction system has sacrificed some fine detail to keep it that way.
1/40th, f/4.9, 1600 ISO
At 1600 ISO there is some image noise visible, but less than most other cameras would be showing at 400 ISO. Again some fine detail has been lost, but colour rendition is excellent and the picture would make a good print.
1/80th, f/4.9, 3200 ISO
At the maximum ISO setting there is now quite a bit of noise visible, and some colour saturation has been lost, but the overall image quality isn’t bad and the picture could still be printed at snapshot size.
