Thanks Curtis, Philip (GREAT shots both of you - I love your portraits and street scenes, Philip).
Curtis - I just bought a D600 a couple of weeks ago... gotta change my profile!
Looking at your kit I see a mix of AF and MF lenses, a fact that can certainly contribute to confusion when considering kit building. You have both 85 and 180mm AF lenses, both of which are fine. The question only you can answer, is how far you want to go into this world of manual focusing. I still had both the Canon 85 f/1.2L and the Nikon 85 f/1.4D when I became enamored with the 85 f/1.4 AI-s. By that time I was committed to Nikon and to MF focusing so the decision to sell the last five Canon L lenses, including the 85 which was my all time favorite, was simple. Selling those lenses I liberated the money I used to buy the 85 f/1.4 AI-s, the 105 f/1.8 AI-s and the 135 f/2 AI-s... the high price spread.
I have no regrets. I sold a number of Nikon AF lenses I'd acquired when I first began my adventure, but kept three, including the 85 f/1.4D, the 28-70 f/2.8 AF-s and the 50 f/1.8. I took the 50 with me to Florida because my partner asked that she have an AF lens available when she used my camera. But I virtually never use AF any longer.
You have some lovely MF lenses, so you certainly have the opportunity to explore further with your D600. Perhaps you will wish to extend your adventure by adding more MF lenses to your kit. If you like fast lenses, the three I added when I sold my Canon gear would certainly fit the bill. They are all exceptionally good lenses and a joy to use.
Have fun. Half the adventure is mulling over the kind of questions you are raising. Kit building really is forever simply because the more we shoot, the more we learn about our gear and the use of light, the greater the desire to keep experimenting. Photography is an amazing hobby for most of us, one that is great fun to share...
