But now we're talking big money. It'd be cheaper for me to move and get a D300.Depends which model you mean. They're all right up there. 1D4 is Nikon D3 level. 1D series is built for speed and reach, and overall they're better at it (arguably) than anything else.
If you shoot tethered, Nikon doesn't write to the card (at least not on anything lower than the D3)
There's ways around that.
I couldn't tell you Tomas. I've only used it in Windows myself, as all my PCs run Windows.
to the OP
Can you not get some Pocket Wizards and make the whole CLS thing irrelevant?
