I haven't actively collected any of the silver nose Nikkors although a few have accumulated over time. 2.1 cm f/4, 24/2.8 N, 28/3.5 H, 35/3.5 PC, 35/2.8 S, 5 cm f/2, various 5.5/55 Micro-Nikkors, 105/2.5, 105/4 T, 105/4 Bellows, 135/2.8 & f/3.5, 135/4 Bellows, 200/4 Q, 300/4.5 H; list compiled off memory as I'm not in the lens house currently.
No Panda Df for me, though. I prefer the Black Beauty.
