I do not think that EV is independent of the ISO.If the camera shows 1 sec, F1.0 at ISO 100 then it is EV0. The camera exposure factors in the ISO set in the body, there is no way to uncouple it. My older Zenit displayed EV on the inbuilt meter. You just rotated the wheel till the pointer matched the needle. Then you read off the aperture/exposure combination off the dial. This was for ISO 100, and the manual explained how to modify it for other ISO - half the exposure for ISO 400, double for ISO 25 etc.</blockquote>
