Yes I really have this idea too, that Swarovski might have optimized the Swarovisions with respect to RB but not being open about it. Maybe it is mainly in the field flattening lens so pretty easy to implement... Maybe I should ask directly. They´d be doing all future buyers a big favor in being open about it.
According to what a Swaro rep told Holger, Swaro designed its first two SV EL models, the 8.5x and 10x42, with very low distortion, but added some degree of pincushion to subsequent models. The distortion levels Holger shows for each SV EL model in his chart and how much "globe effect" is possible from those models perfectly matches the degree of sako's experience of RB in the three SV ELs he tried:
Distortion of the new Zeiss Victory SF: A paradigmatic shift on the binocular market?
I would guess pincushion was added to overcome complaints about RB in the 8.5x and 10x42 models, though I don't recall if the rep came out and said that to Holger. The Nikon SE series and the Zeiss SF series prove that you can design binoculars with flat fields and enough pincushion to prevent RB in most users who are susceptible.
