That piece also specs the lens as a 6 in 4 double gauss
type...
The price point is encouraging indeed!

My e-mail filter works on the subject so it routs off
list stuff into the list folder.
The problem is that the description of six elements in four
groups fits both the Planar and Plasmat types so, without
other information, it does not identify the generic type.
The Planar is derived from the double-Gauss lens and the
Plasmat from the Dagor and their characteristics are
different. Past practice seems to be to use the Planar type
where more than "normal" coverage is not needed and the
Plasmat type where it is. Both types can be corrected to a
very high degree but the Planar type seems to be the design
of choice for fast lenses. Of course, this is all
speculation, I suppose Fuji will eventually have some
additional information about what its lens actually is.
