The Canon being an L lens (better build, probably weather sealed) would not make it a heavyweight... Nor would UD elements.
Of course, it may be that the Fuji just is a "modern" design approach, where the quest for easy sharpness makes for heavy big lenses (think Sigma 50mm f1.4 Art, Otus nr 1 and 2 for instance).
Still odd to be though, because "mirrorless" should mean "compact and portable". Think Leica lenses. Leica 90mm f2 for the M is 64mm wide and 77mm long. It contains 5 elements. That is a lot smaller than the Fuji at 75 x 105mm, even when you take the bigger flange distance into account. And that Leica is 135 format coverable.
The Canon EF 85mm f1.8 USM is actually not much smaller than the Fuji, though. It measures 75mm x 71.5mm, and the Fuji flange distance being 17.7mm and the EOS one 44mm, the length difference is just 78.7 - 71.5 = 7.2mm. Small difference. But yeah, the Fuji is only APS-C (at least, I can't speculate on Fuji starting an FF X-body and is designing lenses with FF coverage already), and that makes it a pretty heavy lens.
The current Nikkor AF-S 85mm f1.8 measures 80 x 73mm, by the way.
