I've had my D300 for quite some time now and have been very happy with it. However, I just feel like I'm missing out on something not having an FX body. When I went from my D80 to my D300, it was a big jump in IQ. Now, after 3 or so years with the D300, I feel like I am wanting that next extra little bit - that FX something that no one can quite describe. I've pretty much resigned myself that now is not the time to make that jump since prices have actually increased due to the limited supply of D700s. So, I'm looking to upgrade when the D800 comes out. I don't know, maybe I'm hoping for too much. I know it is the photographer that makes the image. The camera is just a tool. And while I love photography, my skills are pretty average. So, am I really going to notice that elusive FX difference?
