Not the most exciting image in the world but you might be interested. This is taken on an E510 using the kit lens

It was taken with the kit lens set at 42mm from exactly 4 metres away from target and of course is a small crop from the middle of the frame. Figures on the left are the point size of each line.

Personally I think that 9 point (just possibly 8 point) is legible and it says a lot for the sharpness of that lens. You could easily repeat the exercise with your Nikon to see how they compare for sharpness. If you do please let me know the result
