Can anyone explain how I would translate this <exif:SubjectDistance>4294967295/1</exif:SubjectDistance> into something I might understand? This is from an old D70 photo but I've seen the same thing in data from my D700. Anyone have a clue?

In other words, it's the biggest number that can be expressed with 32 bits.

That's a good, simple way of putting it - thanks!
Here's another way - 4294967295 is 2 to the power of 32 minus one. However we describe it, it's the camera's way of saying "infinity focus"

I keep telling anyone who will listen that these darned things are noting but computers with lenses, like our new car is a computer with a gas pedal. Years ago the 7th Fleet Commander (a 3-star admiral) told me of life: "Too many moving parts."
