I have a question regarding manual focus nikkors: 28mm f3.5, 50mm f1.4 and 105mm f2.5 that I had converted for use on my D200. What is your take on this. I truly enjoy these lenses. Also a salesman at my local store said something about these lenses not being suitable for digital ff sensors. Curious.

We'd have to know more about how these lenses were modified to work on your D200. Do they auto-focus? Do they report the aperture to the camera? Can the camera control the aperture on the lens? Does the lens provide a focus confirmation?
Isn't your D200 a 10MP digital Nikon camera with a cropped format sensor? The lenses were originally full-frame lenses. I can't image how they don't remain FF lenses, but your details about the modifications might help my imagination.
You can just as easily take one / all the modified lenses down to the local store and confirm / disprove with the salesman.

See the camera manual under “Compatible Lenses.”

They do not auto focus and they report the aperture to the camera. They also show focus conformation. They work with aperture priority and manual modes. They all have aperture rings also.

When I was in school, my teacher said the camera does 1% of the work. The remaining 99% of the work is done by the nut in the viewfinder.
When you watch the baseball playoffs, remember that the bat does 1% of the work and the batter 99% of the work. However, they DO use the best bats available. Best wood, thin handles. Believe me, the wood in those bats is totally different than what you and I can buy at the sporting goods store.

What would be the difference between a mediocre FF lens vs a top quality FF lens?

Mostly, wide open and edge performance ...

They should behave the same on any F-mount DSLR. It's easy enough to confirm with an actual camera. Check for a vignette when mounted to a FF body would be my next concern to verify.

Why don’t you just test and find out?
Yes, the edge-to-edge *consistency* is better when full frame lenses are used on APS-C bodies. But overall MTF performance can be (often is) lower, due to other factors.
Examine lens test reports on DPReview to compare the same lens on a D5 and D500. It performs differently.

If you are concerned about the edges of an image then there is something wrong with the composition. Too many get hung up on pixel peeping at 100%. You do not want people focusing on the edge of an image and images are usually not viewed at 100%. My guess is if printed most people would not even notice.

The short answer is FX lenses do produce sharper edge to edge images on DX bodies. One interesting observation is that we see many images posted on UHH that involve the use of the vignette to concentrate attention on the the prime subject. Hence, is absolute edge to edge sharpness a criteria for many users? Just sayin'.
