Question is, was the "Sigmatel" lens really made by Sigma: http://www.fredmiranda.com/forum/topic/1089593 There's some Soligor involvement? Alright, who cares? Sigma has done a couple of weird designs in their pre-"Art/Sports/Contemporary"-period.
In any case, the lens in your chart has nothing to do with the current version of Sigma's 135/1.8. Features and design are too different. Noe of these lenses comes with 14 elements. So it's not just normal evolution
I also don't feel you're trying to devalue my opinion, because I agrre with you - some advanced optical performance generates more volume and therefore more weight, that's just normal. I really do admire Sigma glass and I know I will use it on the D850's 46 MP without problems - all I said was, the 35 and 24 at f/1.4 are rather exceptions.
In the beginning, when I bought one of the first 35/1.4 Art coming to Switzerland I thought "cute, smaller than Nikon and still better performing", with the 24/1.4 optical quality was not much better than with the Nikkor. From then the Art series grew - in numbers, size and weight. The 85/1.4 comes with a bigger filterØ than the 135, same of the Otus'
