Curious about what you think you would gain with the 5D3 over the 5D2 for landscape and architecture. Certainly not resolution, dynamic range, or sharpness. I've been tempted just because it's something new and/or different, but that $3000 is probably better spent somewhere else for this type of photography.
That's what I've also heard. I haven't made the plunge as I feel the upgrade is too costly. I spent the money on the Tilt Shift yesterday.
