I have an older Nikkor 50mm f1.4 and it is just fine, even wide open. I love the Nikkor 20mm f4 lens. Not very fast, but very sharp with good contrast. These are both manual lenses.
Also, I like the Sigma 10-20D zoom lens. Can’t use it enough. It is slow, but lovely. I, also, use a 105mm Micro Nikkor f2.8 lens for closeup work on the AF100. Super lens!
