For those of you who own and use both a D600 and D7100 I am curious to know how each camera compliments your photography interests.
I have a D7100 and enjoy using it. I am considering purchasing a D600 based on my experience with a rental with a Nikkor 70-200mm 1:2.8GII ED VR.
It seems to me that the images out of the D600 are a tad sharper than the 7100. Here are two images out of the D600, the second being a crop of the first. There are no comparable D7100 shots of the same scene, so this is just an impression I have.
I have both these cameras and actually my experience is that the D7100 is a wee bit sharper, although I'd describe it as slightly harder edges.
But I'm not personally so interested in the sharpness comparison and haven't been looking out for it. For me the dual setup works with the DX D7100 as my telephoto wildlife rig and the FX D600 for portraiture, landscapes etc...
I really like that the two bodies are virtually identical in setup. There's only a couple of minor differences, two things that I notice are the lack of a remote control setting on the drive dial and no picture control button on the D7100. But it's a quick fix in 'My Menu' and assigning the Fn button to get these two features accessible. Other than that it's seamless moving between the two.
I definitely notice that the D600 is heavier and I like that for the use I put it to. I also have a grip for the D600 but I doubt I'll grip the D7100. Same battery/charger is a bonus.
Obviously the autofocus has greater area coverage in the D7100.
All in all I find them to be a great compliment to one another.
Philip: Thanks for your comments. I had no trouble setting up and using the rented d600 since the controls are almost the same, as you mentioned. This is a positive for me since my reflexes are honed to work the D7100.
Bob, I can't comment on the sharpness since I do not have the D610 yet .
I have been shooting Dx (D300/D300s) and Fx (D700, D3S) in tandem for quite some time. I have MB10s for the cameras. I shoot mainly wildlife, sport, PJ and documentary . For me it is mostly about the available light or unavailable light .
I'm loving the D7100, my 'toy' camera . The D300 is showing some problems with AF and the D700 has some quirks (metering) since it took a fall, died and was revived by Nikon.
The sizes and weights of the cameras vs the others is a major factor for me now. I have many good lenses but I am also creating a walkabout/travel set(trying to keep the IQ's as high as possible).
I think the same form factor will allow me to use the two, D7100/D610, for just about anything in most light.
If you have all the time in the world, D7100 is a great complement to D600. D7100 is better for small/distant wildlife and macro while D600 is better for low light. On the other hand if you tend to use cameras side-by-side it may be awkward. Too often you may discover that the "right" lens is on the "wrong" camera.
I have a D7000 and a D600. Both are exceptional cameras and produce quality results so I can imagine the D7100 would be even better. If I'm shooting an event I put my 70-200mm on the D7000 for reach of the candid shots and my 24-70mm on the D600 for group shots.
Having both bodies is like doubling the number of lenses in my bag.

It has been almost 3 months since I posted this topic and at that time I used a rented D600 with a 70-200 mm f/2.8 lens. I turned out that the layout of the D600 was very similar to my D7100 minimizing learning time and minimizing the need to remember which camera I was using and where the conrols were. The D600 was slightly heavier, but felt good in my hands.
My intention was to use the D600 for landscapes, low light situations, action sports while using the D7100 for wildlife, esp birds where reach is sometime critical and which the DX format would give me, e.g. a 300mm lens would have an effective 35mm focal length of 450mm. I could do this with the D600 but would lose half my pixels. Either camera could serve as a backup if I needed one.
So, I did purchase a D600 at the time of falling prices with the announcement of the D610. I also purchased the 24-85mm kit lens and really like both the camera and the lens and am happy with my decision. It is working like I thought it would. Now saving up for the 70-200mm.
I travel with a D7000 and D600 with a 300 f4 + TC14E II, 70-200 f4, Voigtlander 58 f1.4 and Nikkor 35 f2. I get some great combinations with both cameras set up. I usually use D600 + 300f4 + TC14E II for 420 mm, with the D7000 + 70-200 f4 for 105-300 range. I can get extra reach by putting the D7000 on the 300 + TC14 and less reach with the D600 on 70-200 f4. The 58 is a normal on D600 and 85 on the D7000. Lots of combinations for four lenses.
