Rob,
I had a good look at one at Photokina, no yellow cast to the glass.
As you suggest, the name is used, but nothing of the design.

Tom et al.,

Do you know if the new Voigtlander 90mm/f3.5 Apo-Lanthar is using the 
lanthanum glass that the original 1960's large format Apo-Lanthar lenses 
used?
The sharpness and contrast of these large format lenses is quite legendary 
but they have a distinct yellow cast, easily visible when looking through
the lens.  The yellow color cast has been attributed to the lanthanum glass 
and was not a problem with black and white film.  It gives a nice warmth
to skin tones with color film, but is unlike the color rendition of other 
lenses.

Anyone seen or looked through one?

Maybe Cosina is just capitalizing on Voigtlander's famous "Apo-Lanthar" 
name that signified the highest optical quality and achievement in its day.

Cheers,
