Ideal Aperture to Shoot for Highest Resolution

Numbers don't lie and its what I go for in evaluating a pre-lens purchase nowadays. And with the MTF50 charts helping along, you can't go very far off the tangent. Avoid lens with ratings below 1950 for center!

Nikkor 18-105mm F/3.5-5.6G VR
Ideal Aperture to Shoot - 5.6 (at 24mm)
Resolution Count (at ideal aperture size) - 2204 (center) / 2074.5 (border)
Notes - O yes, at 24mm, this Nikon D90 kit lens outperform even the Nikkor 18-200mm! So, don't think for a moment its a mediocre glass you've got there.
