So why then would there be a disadvantage for me to buy an FX lens for a DX body if it will still give me the same angle of view as the DX on DX equivalent?? lol I've just confused myself I think....
3rd party lenses are fine if they can do equal or better than the Nikkor. In my experience, I have only come across two lenses that fitted the criteria. The Tokina 12-24mm f/4 for almost half the price of the Nikon version and the Sigma 50mm f/1.4 prime which is better than the Nikon version in my opinion.
I shot a wedding two weeks ago and the 24-70mm and the 70-200mm were the ones that I used the most.
The disadvantage would be cost since FX lenses are more expensive. They are also heavier. And if you shoot wide, the widest FX lens is 14mm which makes is about 21mm on DX.
For non-fisheye, the widest FX lens is 12mm, while for DX it is 8.
I am looking at Nikon's website...

And I don't see a FX lens at 12mm. The widest is the 14-24mm f/2.8.
Sigma has a full-frame "DG" lens that is 12-24mm and a "DC" lens that is 8-16mm. I consider the term "DX" and "FX" to be Nikon specific.
Just keep in mind that the 12-24mm sigma lens for full frame or the 8-16mm lens for crop cameras are about as special purpose lenses as a fisheye is. 12mm on FX is a MASSIVELY wide lens, with a near-fisheye 122 degree FOV at the widest setting. A lot of compositions simply don't work with this kind of width.
Even 24 mm on full frame is very wide, somewhere between a long UW lens and a wide wide-angle. My 12-24 mm on DX tempts me way too often to use extreme settings and it's definitely a lens for special purposes.You have range up to 24 equiv. No problem, you have the freedom.

That's because the focal lengths FX zooms in particular are designed with full frame bodies in mind, but photographers really work with viewing angles when they compose an image. Giving the focal length has just become the customary way to label certain angles of view. This means a 24 mm lens on a DX body (whose crop factor is 1.5) will have the same viewing angle as a 36 mm lens on a full frame body, i. e. it's a moderate wide-angle lens.So why then would there be a disadvantage for me to buy an FX lens for a DX body if it will still give me the same angle of view as the DX on DX equivalent?? lol I've just confused myself I think....
Of course there are disadvantages when using FX lenses on DX bodies. Most notably, it's an issue of whether the focal lengths offered actually suit your needs on a DX body.There isn't a disadvantage.
The 70-300 lens on crop would be like a 105-450 on full frame.
Unless you are more interested in the very long end, the appropriate replacement for a full frame 70-200 f2.8 would be the crop Sigma 50-150 or maybe the crop Tokina 50-135.
There's a new Sigma 50-150 f2.8 DC with OS that has been announced some months ago, but it's still not available.
I also have it narrowed down to the 16-35 f/4 VR and a 50mm prime, or the 24-70 f/2.8 and adding a third party wide angle lens at a later date when funds have replenished.
I'm definitely more interested in a longer reach for this lens, for playing around with some mild wild-life telephoto shots. Nothing that would justify spending more for a 2.8 70-200, but I would like something nicer than the 55-200 VR I had before...
70-200 is not appropriate for crop. I said the equivalent 50-150 DX.
Sure it is. It is great glass and as long as you are prepared for what you have on the short end it is a great lens for any and all outdoor uses.
I would be similar to buying a 120-300 f2.8 for FX.
But if you get the 50-150 2.8 DC matching a 16-50 DX or 17-55 DX, you can then just get precisely that 120-300 FX for a massive 180-400mm f2.8 equiv.
70-200 is not appropriate for crop. I said the equivalent 50-150 DX.
I shoot my 80-200 on my D2x fairly often (when it doesn't have the 300/4 on it) and it doesn't think it's not appropriate at all.
As a long lens, not as an alternative to a 50-150.
