I presently have an 18-300mm lens that I use on my D7000 that gives me an effecive 27 to 450mm because of the crop factor. I plan to get a D800 but have not decided which lens(lenses) to purchase with it. I understand that if I use my 18-300mm lens on the d800, the d800 will automatically go into a DX crop mode. I know that the resolution wil be reduced to about 15mp. My question is does the crop factor still apply so that I am getting an effective reach of 450mm?

Steve,

The resulting photos and field of view will pretty much look identical.

The D7000 and D800 in DX mode will give you the same field of view. However, you will not get the benefit of the "DX reach factor" on the D800 because of the lack of resolution since the DX mode of the D800 has fewer pixels than the D7000.

Exactly the problem.
Why spend twice as much for a camera to get the same results?
You would be a lot better off with a 28-300 FX lens.

True, but the difference isn't huge. The D7000 has 16MP, the D800 in DX Crop Mode has 15.3MP.

I agree with Brian. I own both cameras and lenses and have used the 18-300 with my D800 with virtually the same megapixels as the D7000. You just won't notice the difference. By the way, the pictures were crisp with the combination.

Recently moved to a D800 after a few years with my D90.
I had a 50mm 1.8G and the 105mm VR for full frame, but had not decided which FX midrange zoom I would put on my wish list. I did have the 18-200mm DX, which gave me nice sharp results on the D90, and I decided to try it on the D800 one day so I didn't have to lug the D90 around as well.
An immediate downside is that the useable viewfinder is reduced to the centre only with the automatic crop, making it difficult to frame some shots. However, even with the crop factor, I gained a bit of resolution on the D800 (15 versus 12 MP)
But what I noticed immediately were the wonderfully detailed and sharp images using the 18-200. Using the raw files in LR4 I could pull what seemed to be a blown-out sky back so that it looked perfectly exposed, and recovered detail in dark shadows. So there may be a benefit to using the DX lenses on your D800 just for the better processor and dynamic range. I was stunned. So stunned that I somehow found some cash to pick up the 24-120 f4, a lens that is giving me great results.

You can force FX mode, though vignetting is likely if you do not.

I tried my nikon 12-24 on my D800E to see what happened. At about 15mm I could not see vignetting, though there may be a slight touch on the corners. By 18mm I am certain all vignetting is gone.

I slapped my 35mm f/1.8 DX lens on my D800 and manual override to FX mode. If I don't shoot wide open vignetting is too noticeable.
