ISO Noise Test Results - C-5050 and D70
Abstract - Nagged by the question of how much quality I was loosing by flirting with higher ISO settings, I decided to run a test.
Conclusions - The C-5050 and the D70 both produce low noise results at their lowest ISO settings. And both have slight, but noticeable noise when ISO is increased to the next logical level e.g. from 64 to 100 for the C-5050 and from 200 to 400 for the D70. At higher ISO levels, the noise is obvious and in my opinion, objectionable.
Recommendations - Use the lowest ISO settings for both cameras unless you have specific reasons for increasing the ISO. And if you must increase ISO, try to limit it to no more than 100 for the C-5050 and 400 for the D70.
