The idea that 35mm glass is sharper than glass for larger formats is a relict from befor NC cad/cam production. Almost all current production is ground to the same tolerances, thus they is no penalty to larger surfaces. Most top quality lens have a resolution of around 72 lpm on film at normal contrast levels (the higher resolutions you hear spouted about are for high contrast or arial images, how many of us photograph line drawings) reguardless of format. Highend sensors are near that resolution right now. The next generation should exceed it.
