I bought my first Nikkor 50 (a 1.4 Nikkor-S) 42 years ago. Since then I've owned (or still own) a 50/1.8E, a 50/1.4AIS, a 50/1.4AFD and at least one other 1.4 Nikkor-S. I'll shoot with any of them, any day. I also have a 55/2.8 Micro, and while the focal length is similar, I don's consider it a "similar" lens. Great for macro work, though. The one I use most often? the 50/1.8E, because it's on the FG that I carry with me all of the time. My favorite to shoot with? The 1.4 Nikkor-S, because it looks, feels and shoots like what I expect from a "normal" lens. But like I said, any of them work and work well. All provide a bright viewfinder, easy focusing, and sharp results. At one time I could hand-hold the 50/1.4 down to 1/15 sec in available light, but not so much any more. But I'm still never as happy as with a 50/1.4 Nikkor (any version), HP5+ and Microphen. I hope there's a darkroom in heaven...
