But if you have a FF camera and want to change lens less, then the 28-300mm is the lens that can cover a huge range. But if you have a DX body, unless you are find with the 28mm..
There is no right or wrong, but more on affordability, whatever makes you comfortable. I use 28-300mm on my D90, but I do find the 28mm lacking in some way, but I only use this lens outdoors and for travel. Indoors I would use my 50mm or 85mm prime.
