Having trouble posting pictures here. Will try again, pix are within size range. Favorite old lens, a 200/4 Q from 1963 or 4. This on D7200 at ISO 1000. First image is whole shot, downsized, and second is unprocessed crop, just converted to JPG and run through RIOT for compactness.
Now since it's loaded this time I'll add that I have two of those old lenses, both butchered for AI compatibility without undoing the screwed-on flanges, but otherwise working OK. Not the sharpest tool in the box, but I like the pictures they make, and use one with long extensions for bug hunting. I was out looking for bees and things when I noticed that tree swallow in the house, so took off the extensions and fired. Using a monopod, sharper results than expected.
