Planar lenses are older still and are five or six element designs with wider apertures than the Tessar.
Sonnar lenses are telephoto designs, probably five elements.
Then we have the wide angle Biogons, Distagons, etc.
Many lens designs may well start off with the basic concept of one of these designs, particularly symmetrical designs, but computer design and new glasses have moved things along very considerably.

Set a small aperture and focus on a point one third of the way into the scene. This will maximise DOF.

Here we should really be discussing the competition, the pictures so far really being pretty harmless, which is what we might expect.
However, all are entitled to an opinion.
