Yes perhaps, The Mk1 was mostly metal, the switch for AF/MF was plastic, but it was a HEAVY lens for the $160 I paid for it... Definitely heavier than the 50mm F/1.4 Nikkor lens I have for my D200... Perhaps not quite as robust as the current Canon 50/1.4..
In any case, Buil's test using a full frame sensor would definitely have shown a much more pronounced case of coma due to the 0.4x bigger sensor size.. Obviously though, not all optical elements are created equal, and the tollerances for optical mis-alignment might need reviewing..
