"Aristostigmat" ???
yes, that's right; it is a triplet but with cemented elements at each end
(in one reference anyway), so it does have five elements in 3 groups...
in any case, the point is that "Ektar" doesn't refer to lens element/group
configuration (cf. Tessar) but rather to a branding by Kodak of its better
lens with this name ;-)
