I have not given up, but I am anxious to see it. I have a D200 with a bad shutter and a D300s that still works. I use a two camera rig to shoot musicals, so I need to replace the D200.
Bottom line: I'm set up for DX. It does what I need. I don't want another D300s because it's old technology now. I've considered the other options, but a D400 is what I need.
I have another musical in March. Now I usually put my 28-70mm f/2.8 on one camera and the 70-200mm f/2.8 on the other. But unless I can come up with something, I'll be doing a lot of lens swapping for that musical. Sure would be nice if I could get a D400. I guess it's too late for that now, but until I replace the D200, I'll be in the lens swapping in the dark mode.
