Why don't AF points expand further to edge of Camera Frames?

focus and recompose - AF points on the outside of the frame are pretty useless if you just use this technique. This is precisely up until recently not all of the AF points in canon cameras were cross-type f/2.8 sensitive ones...

Because that would require the focusing system to be the same size as the sensor, which it is not.

Can you also find out which AF points are cross points?
I find that my D80 (which has the same layout as the D3000 and D90)does much better with AF when a cross point is selected. I normally use the middle point of the second row from the left or the center point. I try to avoid the non-cross points.

You can get rocked by this if you are shooting at wide apertures like 1.4, be careful...

I'd say that it's probably to stay out of the barrel distortion range of various "cheaper" lenses.

I might even drink blue moon with an orange slice on the rim (ewww) just to hold the mighty 200mm f/2.
