Hey I am looking for a telelens, and first I was thinking of saving up for a 400mm f2.8 VR. That is going to take a while cause the price here in Norway are about 13000$. Then I saw someone that is trying to sell Nikon ED AF-I Nikkor 600mm 1:4 D not far from me to the price of 2800$. As you can see thats a big different moneywise, but its also an oldtype of lens. Is the 600mm "worth" to buy? I guess its a quite good lens, but its missing VR (for 4 more stops), its "only" f4 and its bigger and heavier that the 400mm. I like the 400mm f2.8 cause of the VR, f2.8 and you can put a 1.4 teleconverter so that you have a 600mm f4 with VR. But still its about 10 grand more to my wallet, and its going to be hard to convince my better halv to agree on a lens that costs that much Any suggestions? Edit: Forgot to tell that is shall be on a D3.
