From everything I've read the 24-120 lens is one of the poorest performing lenses Nikon has ever introduced. DXO gives it a very low rating and the so called experts don't seem to have been enamored with it either. I've never owned or used one but on here it seems to be a very popular lens. I have been thinking about getting one for awhile now so any input from y'all about your personal experience would be greatly appreciated.
