Nikon AF-S NIKKOR 28mm f/1.8G

Im really going nuts here trying to study all these different lenses with all their issues and problems and strengths. I have a D800 Nikon and I’m trying to figure out what is the best lens to use for it. In the above review on the 28 millim 1.8 f you state that it has Optical flaws like most other lenses. Am I to take it that there are some that do not have Optical Flaws? I see there’s issues with vignetting, chromatic abberation, Tstop, sharpness, uM and the like. With the exception of the Carl Zeiss otus which is way out of my price range every other one seems to have a weakness. And even the Carl Zeiss otus has a weakness in that it is not autofocus. each of the lenses which follow from nose descending orders seems to have cut some kind of an issue in one of these areas or another I’ll be it ever so slightly. But I have no idea what order of these areas is most important which is least important how much is too much of a flow to be acceptable or not? I’m completely lost in terms of what the proper balance is for the greatest finished product period ended and then of course there are issues with photo shopping and things like that which can offset and adjust some of these flaws or weak areas in these lenses butt I just don’t know. I am kind of looking for an out-of-the-box Superior lens for under $2,000 which will maximize the output of the d800e. the 70 to 200 millimeter Nikon is too heavy to hang around my neck so I love to take landscapes on a tripod. But I would like to be able to use the same lens for multiple uses. I would like to be able to walk around on the street and take fabulous pictures and take wonderful landscapes with the lens. Later on down the road 5 years from now maybe I’ll buy a second lens but right now I need something that will do 35 or 36 megapixel sharpness and they’re only appears to be a handful of lenses on dxomark which will output that kind of sharpness. I have a ton of questions but I think I’ve asked enough for now thank you so sincerely Richard
