D600 or no D600?

The news has been buzzing about the new D600 from Nikon. You probably already know this is the latest feature rich full frame DSLR from Nikon, at a "reasonable" price. Even Ken Rockwell pre-ordered one for himself.

I have been dreaming of this camera all summer, really wanting to upgrade from my D5100, but now that it is officially available I am probably going to pass....  The reason? The cost. Below is a breakdown of what it would cost for me to have a configuration equal to my D5100 setup.

Lets break it down:

1) Camera Body: $2,100
2) Battery grip: $322
3) 3 additional batteries @ $62 each
4) Nikon 16-35mm FX Ultra Wide angle lens to replace my 10-35mm DX lens: $1199
(Lens needs to support a 77mm filter for my current filter collection)

Total: $3,807

So now the cheap D600 is no longer a cheap upgrade for someone moving up to a full frame camera.

The logical next upgrade would be the D7000, but it isn't a big enough difference from the D5100 to make the leap. So for now I am going to wait for a few things before I upgrade:

1) I want to see what Nikon releases as the next generation of D7000 level cameras (released 2 years ago)
2) Wait to see if the D600 drops in price AND if a new selection of cheaper Ultra Wide angle lenses hit the market. Yes, I know cheaper does not mean better.

Next you may ask, why do you want to upgrade? These are a few of the reasons...

1) I want more controls at my fingertips and not hidden in menus
2) I want a histogram to view prior to shooting
3) Hoping for an onscreen level
4) Additional bracketing options
5) More autofocus points
6) Custom pre-sets
7) Better weather proofing.

D600 upgrade rambling

Now that I have seen photos of the future Nikon D600, I am wanting it even more. I am now realizing that the lens I use the most is a DX Tamron 10-24 lens and it can not take full advantage of the D600 sensor.

If I decide to upgrade to a D600 I need to figure out what Ultra Wide Angle lens will give me the same field of view that I get with the DX camera.  My research shows that many Ultra Wide FX compatible lenses do not allow you to screw on a filter. So not only do I need an equivalent  viewpoint, I also need something that will support my 77mm filters.

I am still new to the FX vs DX world, so it is hard for me to figure out which lens I should consider buying (without breaking the bank).  It looks like Nikon has a very good Wide lens but I am not sure if it is wide enough or equal to the Tamron.

If you have any thoughts, I would love to hear your feedback.
