Spoke again with Nikon on the D600 oil/dust issue - A fix is on the way! Locked

How would you expect him to answer the question ? Random or not, Nikon would know exactly which serial numbers would have the potential fix. That's the whole point of having serial numbers. When they needed to do a recall for bad batteries, for example, they knew exactly which units to recall from which stores.

Regardless, do you seriously expect Nikon to tell you how to use the serial number to identify a D600 with a potential fix ? The serial numbers of the post-fix units would be all over the Internet in 24 hours and the pre-fix D600's would be impossible to sell. Nikon would have to recall, fix, and re-label the serial numbers on all these bad units. Basically, by releasing the serial numbers for the post-fix units they have just forced themselves to do a recall on all existing inventory which they are obviously trying to avoid for cost and profit reasons.
