Just a random shot to test a 20 years old manual lens on today's camera to see its effects. It's really hard to do manual focus these days. :)

A British Airways Trident Two (G-AVFN) stands at Heathrow's maintenance apron in the early 1980s, undergoing testing. Note the angled tailplane - a characteristic of these classic planes, whereas more modern craft just use elevators rather than moving the whole surface. My first flight was on a Trident Three, coincidentally just weeks before they were all withdrawn.
testing out new lighting equipment. Nikon D600, with Mitakon Zhongyi 85mm f/2 Len and the Orlit Rovelight RT 610.
Using two GN Auto Nikkor 45mm 1:2.8 lenses in a comparison test mounted to a Nikon Z5 via an FTZ adapter which was then placed on a Benro TAD28C with an IB0 panoramic ballhead. I set up the tripod on top of a manhole cover so it would be easier to level it.
The 764085 lens has one improvement over the older 714595 lens in that it has a better formula of multi-coating on the elements.
The older lens suffers from a fungus infection, and I was only able to get the rear element pair out to clean most of it off. I have no idea where my Ponds cream has gotten to, as that is the best stuff to get fungus off a lens, so I had to settle for plain old 91% isopropyl alcohol and lens cleaning fluid.
I took a series of photos 90 degrees apart in order to get the different lighting conditions and angles. I put the camera in full manual and only made exposure and focusing adjustments. I may have missed on the focus because I haven't used the camera for quite a while and am not used to interpreting the focus assist readouts. I used the original HN-4 hood on the newer lens, and my cobbled-up replacement one on the older lens. I can see no difference in performance between the two hoods.
The lenses themselves, that's another matter. Besides any obvious differences in focus, I find the older lens not as contrasty as the newer one. But I wouldn't say the older lens is bad. It could still use a full cleaning, though.
First test with Leica C3 zoom camera. It is a very beautiful camera, solid built, quiet to use.
Lens is quite sharp.
