I am a beginner in DSLR, and would like to purchase another lens other than my kit lenses came with my D3400. After so much googling, and reading blogs, I have decided to purchase one 50mm lens. I have found 2 options, either Nikon AF-S Nikkor 50mm f/1.8G or Nikon AF-S Nikkor 50mm f/1.4G. 1.4 is expensive than 1.8. I did a googling for 1.4 vs 1.8. All of the blogs were technical (coz I don't understand that "tech language") and I am looking for some "simple to understand" definitions, like the image look sharp, background will look blurrier, perfect for night photography etc. I would like to know the difference b/w D and G also.
