<p>I just got a Nikon F3HP and is looking for a primary lens. I'm not a big fan of carrying a lot of lenses, so I want to start with 50mm for now, and narrowed down my search to the following options: Nikkor-H/HC/Ai 50/2 or Nikkor-S/SC/Ai 50/1.4. I feel that I don't really need 1.4 all the time, so probably 2.0 is more suitable for my needs since I love to shoot wide open. <br> Is there any difference optically between 50/2 Pre-AI and AI? Based on pure specs it's the same lens (I understand coating is different though between H and HC/AI) - but for some reason the constant great feedback I can find is about Nikkor-H/HC ("Nikon summicron", "special character", etc) - not AI. Or maybe the rendering difference is only because of single coating on H? </p>
