Greetings folks. Currently I have the AF-S NIKKOR 50mm F1.8G. I use it as my street lens on my D750. Up until I have started to use my Sigmas at F/1.4 on DX bodies, (DX Versions)A few weeks back, I never thought I would see a reason to get the AF-S NIKKOR 50mm F1.4G. My question is simply this. How does it perform compared to the very good AF-S NIKKOR 50mm F1.8G? I am sure there are folks who have both here. I shoot the 1.8 version wide open all the time and it is sharp as a tack. Would it be reasnable to think I would get decent photos from the F/1.4 version as well?
