It is certainly not a classic double Gauss or one with modest modification but 
has echoes of it with the symmetric doublets in front of the rear aspheric 


Even with super computer aided design, there are only so many efficient ways to 
tame aberrations.   I think CV really excels in making niche lenses that hit it 
out of the park and especially like the Apo Lanthars.
That is a really a nifty fifty and have had it in my  basket a few times w/o 
pulling the trigger.  I have a CV 40/1.2 that doesn't have that blazing 
resolution stopped down but doubles for environmental portraits at wide 
apertures and
sharp enough stopped down for landscapes  but not to the level of the 50/2 apo 
lanthar. That lens was not announced yet when I got my 40/1.2. The 40 gets a 
bit busy in the transition zone at times but no lens is perfect in all ways. 

I think CH had some building shots with all the OMZ 50's.  The 50/2 macro 
achieved some A+ rankings on Gary Reese test and wonder if it truly discernably 
better in CH's hands than the 50/1.4. 

Nifty 40's are nice too, Mike
