It isn't Zeiss route but the 1970s Vivitar Series 1 route. The glass they advertise ("Tantalum glass") was the mainstay of Vivitar Series 1 lenses.Seems like SLR Magic is going Zeiss route - more elements for more corrections. Leica has been trying to do more with less, which I find somehow more pleasing. I do like Zeiss 21mm lens though.
Most likely they have additional elements in lieu of asphericals.It isn't Zeiss route but the 1970s Vivitar Series 1 route. The glass they advertise ("Tantalum glass") was the mainstay of Vivitar Series 1 lenses.
Very thick elements and heavy.
Zeiss and Leica use rather more sophisticated materials. More expensive.
What does not make sense is that this complex configuration does not appear to give any better result.
Yes, it does not have to be better.Most likely they have additional elements in lieu of asphericals.
It does not have to be better. Different and good quality will be enough to make it worthwhile.
Best,

I am sure the army of women with abacuses is no longer necessary to calculate lenses. Just fire up Zemax, and off you go... Maybe next thing will be about designing your own lens and having it actually made?Yes, it does not have to be better.
Aspherical elements are in a lens to correct spherical aberrations. None of the f/1 Noctilux lenses or the Canon 50/0.95 have them. Only the f/1.2 and the f/0.95 Noctiluxes.
With so many elements, even the computation is going to be complicated as the variables are increased many fold.
It will be interesting to see what the real specifications of the lens are- in addition to the size and weight.
The focus throw from 0.7 meters to infinity is about the same as the focus throw from 1 meter to infinity on the Noct 0.95.Ashwin, how is the focus ring? Short throw, long throw? Weight? Thanks.
