I searched hi & low if this ? was asked, but haven't found it. Since Nikon's lowest ISO setting has (until recently) been 200, I have always thought Canons (or any camera with a "native" 100 ISO) had a noise advantage (at 100). We all know 100 has less noise than 200 on a camera. However, after having learned about "native" ISO's, Nikon's "native" ISO continues to be 200. So, was I WRONG in my thinking? Does this mean that Nikon's ISO 200 will have basically the SAME amount of noise (or rather, lack of) as ISO 100 in a Canon? Are they functionally equivalent? Up until now I had resisted buying a Nikon, thinking Nikon's 200 was equivalent to Canon's 200, but maybe I have to reformulate my entire way of thinking about Nikons. Thanks in advance!
