I was disappointed in the DF. What I was hoping for was an actual FM (or FE) with digital innards. Something similar to what Leitz did with the digital Leica. What Nikon brought to market always seemed a bit clunky although it did have some nice specs. I was also hoping that Nikon would build a modest system around the camera with grips, etc. What we got seemed to be more of a tribute camera than anything else. The fact that Nikon only produced one camera bearing that name seems to confirm this idea. No DF2 for you!
The Zfc seems a bit closer to what I envisioned. Especially, the new black one. It still isn't perfect but I'm guessing it'll fly off the shelves this holiday season. Unfortunately, I have the same misgivings about this camera with regards to it's longevity in the Nikon lineup. Actually, I'm surprised it's still around.
