1DS Mark II, 1D Mark III, or 7D as Secondary Body

Right now, I'm shooting with the Canon 5D Mark II and Canon 50D Combo. I'm looking to move up and give the 50D to my girl. Looking to spend under 2K.

• Canon 1DS Mark II
  
• Canon 1D Mark III
  
• Canon 7D
  

The 7D has the same controls as the 5DII, which is a huge advantage IMHO. I like the 7D, it's a nice camera, however i'd probably think seriously about the 1DIII in your situation.

Secondary to me means something that's easy to carry. 7D gets my vote.

I've only used 5Ds and 20Ds but I've heard very good things about the 7D; mostly about the focusing ability, which is supposed to be phenomenal.

in the same boat, might go with the 7D because the battery is the same as my 5D MII and the simple fact that the LCD is much better quality and it uses the newer UDMA Compact flash cards

1d mark III would be a perfect compliment I think.
