1D MkIV swop for my 7D?

Not that the OP has laid out the specifics of the "trade" but we're all assuming trade + cash from him. So he's already lost out some resale from the 7D, he's going to be forking out more cash to make up for the difference. Or are you saying that the money he already spent on the 7D won't be considered lost?

And I'm pretty certain you made the statement "they will hold their resale value longer" more as a blanket statement and only now trying to apply it to the OP's situation, where the math still doesn't add up.

Point is, 1D4 is a GREAT camera. It's a better camera than the 7D in almost every way imaginable. If it meets his needs then sure, trade up. But don't think that "resale value" is one of the reasons to do so. The numbers don't lie. Resale value isn't better.

I think I hear someone calling you...

No brainer deal as far as I am concerned.

I agree, I have both but the 7d has seen little use since I got the mk4.

I would do the trade.

On topic please, and let's keep it friendly...

Resale value isn't even a factor in the decision. Resale value is nothing but an excuse to do nothing or buy something you can't really afford....None of this was a consideration in his original post.

I say go for it!

Sometimes the advantages aren't always "on paper" or in "black and white".

There's just "something" about shooting with, and especially OWNING a "PRO" camera body. The way it "feels" in your hand, the smooth, head turning, clickclickclickclickcl​ick... sound of the 10 FPS 1D Mark IV (or 1D Mark III)over the "plasticky" clack-clack-clack-clack-clack...of the 7D, the ruggedness, the "I'm Bad, Uh Huh, I'm Bad!!" feeling you get when shooting with a "pro" camera etc.

These are things that don't HAVE to be justified, they're just cool!

As far as not having a wide angle lens for the 1.3x crop cameras, there's the Tokina 11-16 which is usable without vignetting from about 12mm to 16, the EASILY modified Canon EF-S 10-22mm lens which is then usable from about 12 mm (even 11 mm if careful) to 22mm. (and both can then use filters). The unfilterable Sigma 12-24 etc. So there are plenty of ultra wide choices.

This is a no brainer!!

Go for it!

And do let us know how you feel after using MkIV.

ok, so you're comparing a 1D3...

what does a 40D go for? Compared to what it went for new?

T1i?

Well, you can't really compare the 7D's depreciation to the 40D or the T1i...especially since the 7D is an entirely new breed in the EOS system. You'd have to draw inferences based on how the Nikon D200 and D300 depreciated. So, after 1 generation, the D300 dropped from $1700 to $1000; after 2 generations, the D200 dropped from $1700 to $500. Assuming that the 7D line will be updated every 3 years, then the 7D will not lose that much value per year compared to the 1D series.
