Help!!!!! Nikon D600 With Nikon 24-120mm f/4G ED VR AF-S lens

The size difference is what will will make the difference on a long trip, it also reduces the size of the bag you need to carry it around with.

Also, my 24-70 F2.8 I used to own was not sharp at 24mm.

I find the 24-120 F4 very sharp even at F4. Just as sharp as the 24-70 F2.8 I owned.

Only negative for me is the vignetting which NX2 cant resolve completely. Hopefully Nikon will address this in an update. The lens hood will also allow flare more easily than the 24-70 F2.8 hood.
