I'm planning on buying a D800 in a couple of weeks, and I've spent a long time researching lenses to go with it having no real knowledge of the Nikon line-up. I can only really afford two lenses to start with, one of which will be the 50mm 1.8. I'd like a zoom to go with it is well and I'm tied between the Nikkor 24-120 f4, Nikkor 24-70 2.4 and Sigma 24-70. I've got the last one on my K5 and it's my most used lens as I like the focal range, sharpness and contrast it gives. Of course, on the D800 the equivalent range would be 35-105 so the first zoom listed would be closest. I rarely want anything outside of the Sigma's range, and hardly ever fit a lens longer than it to my K5.
My thought was to go with the (not especially fast) 24-120 at first and then later add an 85mm, and then a 12-24, 24-70 and 70-200 as funds allow, does that sound like a good plan of action?
