You were supplied with numbers, C. Where are your numbers to disprove those? Just asking for more, and then more, and then... is a tactic that never proves anything but the unwillingness to believe even numbers. Rather odd. Hasselblad held an online webinar a few months ago on the topic of lens design. And though it is now possible to produce very good lenses in a short time between specification and acceptance, due to computer power and such, many old ones still hold their own very well. In short: it is now much easier to produce excellent lenses, doesn't mean old ones aren't, or can't be excellent as well.
