Which of the vintage prime and zoom lenses is the sharpest at the focal length of 50mm? And how do they compare to the Sony SELP1650 kit lens for the alpha 6000 camera series?
Because the shots were taken with an alpha 6000 camera having an APS-C sensor, the angle of view compares to a 75mm focal length on full frame. Decide yourself which is the best lens by pixel peeping following 100% crops.
The test scenario
All shots at the lens shootout location were shot with a tripod, aperture f8 and fixed ISO 400. Almost the same lighting condition for all lenses. Shutter speed was calculated by the camera for proper exposure by aperture priority automatic mode “A”, which enables manual control of the aperture.
The observation camera marked with a red cycle is used for the 100% crops to check the center quality and the antennas marked with a yellow cycle are used for the 100% crops to check the corner quality:
Now pixel peep yourself, which is the sharpest vintage lens? I included the exposure times.
SELP1650 f3.5-f5.6 kit lens, shot with 1/800s
The SELP1650 APS-C lens is the kit-lens for the alpha 6000 camera series.
Vivitar Series1 24-70mm f3.8-4.8, shot with 1/640s

Tokina SZ-X 28-200mm f3.5-5.3, shot with 1/500s
Interesting, the tokina lens is much slower than indicated at aperture f8! Two times more light at 1/500s instead 1/1000s of the Minolta and Zeiss lenses means a true f11 aperture instead a fake f8 at 50mm. See details about this lens here: Tokina SZ-X 28-200mm f3.5-5.3
Contax Zeiss T* 50mm f1.7, shot with 1/1000s

Minolta MC Rokkor-PF 50mm f1.7, shot with 1/1000s

Which lens wins the 50mm shootout?
In my view, the Minolta MC Rokkor-PF 50mm f1.7 and Contax Zeiss T* 50mm f1.7 are far ahead of the other lenses regarding sharpness and contrast at center and corner. The Minolta lens is even a little bit sharper than the Zeiss, which surprises me. The verdict might be different with full frame sensor shots, as only the sharper middle 2/3 of the lens is used at the shots of this test with an APS-C sensor alpha 6000 camera.
If you have a different verdict, please let me know in a comment below.
By the way, the alpha 6000 camera converted the RAW file of the shot with the Minolta lens into a JPG-file with a filesize of 10366KB, the Zeiss lens into a JPG-file with a filesize of 10144KB while the shot with the kit lens was converted into a JPG-file with a filesize of 8992KB. Better image quality results in a larger JPG-file, right?

This shootout demonstrates, that vintage prime and zoom lenses with 30+ years of age can deliver good or even excellent image quality with modern camera bodies, if the right vintage lens in proper condition is choosen.
