I have been pondering either the Nikon D90 or the D300, but now that the Canon 5D Mark II is out, I'm tempted to convert. The first two, of course, are DX format and the preferred Nikon lenses to use are the DX series, where the "conversion" factor for the cropped sensor is 1.5 to 1 (i.e. a 20 mm DX lens gives you what you used to get from a 35 mm film camera lens).
Dumb question: For the so called "full sensor" cameras like the 5DII, does that mean we're back to the old rules that applied to 35 mm film cameras on what to expect from a lens? I assume so. Literature seems clear that the 5DII would take the old (pre-digital) EF lenses, not the digital EF-S lenses.
If that's so, you Canon guys out there: What's your favorite lens choice for wide and macro work? I was looking at the Tokina 11-16 and the Nikon 60 macro in the Nikon digital world, but now I have to start all over.
Any help out there? Thanks.
