>Nikon 24-120mm f/3.5-5.6 NOT RECOMMENDED (one of Nikon's 10 >worst lenses of all time). This is what KenRockwell says about >this lense,
The 24-120 f4 is a totally different kettle of fish to the older versions. Nikon has had 3 versions of 24-120 over the years and this latest 24-120 is by far the best.
I have a 28-105 from my film shooting days and an 18-200VR from my DX days. Recently bought a 24-120 f4 to go on my D800 and ran a bunch of test shots with all three lenses on the D800.
In increasing order of IQ they rank 18-200, 28-105, 24-120 f4. The 28-105 is marginally better than the 18-200 in terms of contrast and has a slight edge in sharpness. the 24-120 is significantly sharper than both of the others, right across the range, including wide open and in the corners. It has signifcantly better bokeh than the others at same aperture due to softer edges on the out of focus highlights. I am finding I really have no further need for my two older midrange zooms.
