Feanor,


If you got-get it. I know that each time i have settled for something less,I end up regretting it. As mentioned by so many others, there are a dozen different ways to come close to the range you want, but they all have significant limitations. I too am seriously contemplating the 500 f.4, but the money is not available yet. ALthough, I don't think i would give up my down payment on a house, I would certainly look for a deal where the down wasn't as much. Back to the 500; one thing I have realized is that when you buy a sigificant peice of equipment, there is always something else you are going to need or want. In this case, good usable support, new type of filters etc. For a good tripod and gimbal head, you are talking another grand or more.If you decide on something else, the 100-400 is a great lens. Its versitile, clear and you can get high quality background blurr. I personally have grown to really like the slide zoom on it--well, there is my 2 cents worth. Good luck on your decision.
