Last week we got our new level 1 camera’s, The Sony X70. We have not shot anything with them yet but initial impressions are good. Alot of features and great specs for a camera in this price range, the ergonomics and layout of the buttons is not the best but is good enough for level 1 students. Sony does not state the iso of this camera meaning that is must be pretty low. We tested it to find out.
Native ISO of the Sony X70 at 0dB is about 125.
We explored this further to find out iso-dB equivalents. They are:
MAX 33dB=6400 iso
We also looked at acceptable noise levels on a iKan monitor. The noise was very clean up to about 18dB and it was usable to 21-24dB. We will test again with a better monitor to see if those numbers are actually clean.
