The D700 creates a need for lots of expensive glass and is off the table to this point. Its just not realistic in my situation.
I am split in my choices now, 7D(if I just look at this in cost) would allow me to spend the extra money on the 135L I want rather badly, but would also create a need for an ultra wide fast lens too. My real fear is buyers remorse with the 7D, I dont want to find myself wishing I had gone with a FF after the fact(for all the benefits of a FF, first being the better ISO performance). In the end I know one day I will own a FF body, why put that off?
A 5DMII purchase will create the need for longer glass and up the price there + the cost of the 5D itself.
very very tough call.
I don't think it's a tough call.
If you want good glass, then you'll need to skimp on the cost of a body (which leaves you with a used 5D classic or a crop body).
Honestly, I don't know what you've been reading or who you've been talking to but the difference in ISO performance isn't that drastic (don't get me wrong, the difference is there, but it isn't as big as you seem to think it is)
I own a 7D, and have owned the following lenses.
24mm f/1.4L II
70-300mm f/4-5.6L IS
I have never thought to myself "Oh if only I had a full frame camera I would get better shots" ... Only advantage a full frame body will give me is significantly better isolation in portraiture, all the other factors are nice, but not $1,000 nice.
