What we lost in recent lens technology?

Ernst Leitz Wetzlar Summitar 50mm/f2.0 and Elmar 90mm/f4.0 are the tool I would like to use for shooting on Nikon Z8 for the time being. Former has angled illis window and latter does no or slight coating on every glass element. Both of them have L39 screw mounting flange.

Summitar is a predecessor of famous Summicron because of its extraordinary performance in resolution. Less power of resolving is more moderate edge drawing leading to gentle line. More softer pics would be obtained as a matter of fact, probably because of residual Spherical aberration. Consequently, I dare chose Summitar than commonly prevailing one, both of them are designed similar with Gaussian symmetric with the iris brade between, also the fuselage construction with retractable are the same, so it's difficult to tell which is from a distance. The way of atmospheric resolutions are different each other, this is not a title which is the sharper.

As for Elmar 90mm/f4.0, earlier model, black painted, no coating and a bit heavier because of brass fuselage construction, has tasty character.Triplet design invited this Elmar has les inconvenient reflecting surfaces, 6 in total leading to more transparent resolution. I know that recent lenses are produced with multi-coating and more lens element to eliminate abberasins also aspherical element application. And eye-openingly clear and brilliant pictures are common especially corners. Complicated lens designing requires so sophisticated machining technology, lens element it self, lens case also does and increasing reflection surfaces also coating surfaces inviting resorption of light source, establishing the centricity of every element, precise matching and fitting between lens element and its case. Product quality must be checked so carefully on the way of production. 

From this point very selfish and self-contented opinion would be described, I feel that something is lost in the pics taken by such a recent lens designing---something important that should not be lost. It's a very difficult task to explain it in word, resolution of atmosphere, smell of air or temp and moisture, very small sound that is difficult to be discerned at that time. This tendency is discerned when monochrome method is invited for the works. This is why I prefer old less lens element design to new and modern computer done ones.

All the ancient lenses take good pics also newer ones, my opinion is just depending on the comfort level of ones Hobby.

Trifle is nothing but piled ones are not so but great.

The joy of life lies in noticing small, little and tiny things?
