All examples were taken with the Sony a7c (FF, 24MP).
The Anastigmat Victar 50/2.9 lens is old (from the 1940s), optically simple (it's an uncoated triplet). Therefore, the photos look vintage. But it's not all that bad, the key is to increase the contrast and choose the right scene to shoot.
Landscapes lack resolution at the edges and corners, even with the aperture closed (f/8-f/11).
But in the center, the resolution is surprisingly good, even at f/2.9:
Vignetting is also low.
But it's better for shooting subjects at f/2.9.
A certain softness is present, but there is also background blur.
With small subjects, the "soap bubbles" of a triplet are present.
But a sufficiently large minimum focusing distance will not allow you to get large "bubbles" in the background.
Triplets are very demanding in terms of optical element alignment. It is possible that this is not the best copy. But the level of photographic quality back then was very different from today (this applies to everything: photographic materials, cameras, lenses).
