I assumed when you wrote "0.0" you meant that you had dialed in 0.0 exposure compensation
I read it the same way. I also took "3@2.8" to mean 3 seconds instead of 1/3 second.

Try with a white piece of paper and the blackest thing you can find and then go from there. I suspect the "problem" is just that the banana and avocado are about the same reflectance. Colours can change the way we perceive brightness.

1. According to the camera/manual the AF and AE spots are linked, but I could be reading that wrong
There is a custom option to control whether the AE point is linked to the AF point, but that's only for matrix metering, not spot. Spot is always center, period. In matrix metering, of course, the whole field of view is used, but if the option to link AE to AF is selected, the area of the field where the focus is will get extra weight in the calculation.

BTW, looking at the pictures themselves, I'd say you've definitely got the top edge of the fruit close enough dead center that I'd be really surprised in the background didn't affect the metering. And the part of the avocado closes to the center of the picture in #1 is indeed the lightest area of the avocado. So again - I guess I'm not *that* surprised the spot meter would read these scenes the same way. Come in closer and center on *just* on the avocado or the banana and you'd get a different story.

As a newbi I am learning much in this thread.

It is my understanding that the "linked" AE and AF was more about time or action that is: that exposure and focus was done at the same time, linked to the action of actuating the shutter; it is not about linking them to the same "target." This is rather than having the AF button controling the focusing while only the exposure is taken with a 1/2 pushed shutter release. So find it more useful one way or the other.

Is this correct?

No. The option to "link" them really is about location - the particular spot that the camera focuses on becomes the spot the has the most influence on exposure. There is a *different* option (AE-L with focus lock) that controls whether AE is locked when at the same *time* as focus or not.
