My previous film-era wide-angle zooms were the manual focus 25-50mm f/4 and the autofocus 20-35 f/2.8. The former was a joy to use with film but is quite large and heavy. The latter is better as an autofocus lens, and it's quite poor in the outer reaches of a photo when shot at f/2.8.
While I've been using only digital for the past 5 years, I've kept my old film cameras and lenses and I still expect to use them once in a while. While I haven't actually done this yet
, I went ahead and bought a copy of the Nikkor 28-50 f/3.5 for its small size and decent photographic quality, with the expectation that it could be a reasonable walkabout lens. I could always throw in my Series E 100mm f/2.8 for a very small and lightweight kit.
I went ahead and did some casual test shots - nothing rigorous, all handheld. I didn't alter colors or saturation directly, but revised exposure, contrast, and highlights as needed to avoid or minimize clipping. All photos are modestly sharpened. As always, any negative results may be due to sample variation or user error.
I found infinity to be quite soft, especially at the wide end. I'll have to return to that with a tripod and live view and see what I can find out. This might be sample variation or even wear and tear; my copy has the stiff zoom action others have mentioned. F/3.5 is not that sharp, but then these were handheld shots on a D7200, with focusing done via the focus dot. Your results may vary. One of these days I need to get a Df or Df2.

Actual pixels from the selected focus point. The spiny object is a fruit to a botanist and a seed capsule to everyone else.

Flowers in macro mode. These flowers always give me fits as the red channel blows out so massively it's hard to fix without serious underexposure. So please tolerate my processing in which I tried to tame the raging histogram.

Actual pixels; I tried to focus on the center of the flower, and the insect took off before I could catch it on the flower.
