You're quite right. For me, it's been eye-opening how design choices made for enlarger application pan out when using the same lens for capture. Nikon in particular really over-engineered their ELs with a view to optimising transmission and minimising aberrations, and perhaps had an eye on the application of those six-element designs to large format photography - whereas Leica, for instance, built the Focotar to do one job only. It does that job well, but the Nikkors still (arguably) take better pictures. I've spent some time comparing Fuji EX and Nikon EL lenses in the last few months - less 'pushing', more 'ripping up' their performance envelope. Such stress-testing has revealed properties that would be less obvious (and are less relevant) in their target application, but if I failed to offer a worthwhile perspective on the topic at hand, I'm sorry for butting in.
If it helps, at 'working' distances of 1m and above, the Nikon resolves better in the outer frame, but the Fuji is slightly sharper in the centre.
