5D2 is lighter and smaller then D700, although it is lesser a camera too.
No onboard flash, no focusing assistance lamp. Center AF point is very accurate, however other focusing points are quite mediocre. Canon implementation of Auto ISO is a joke.
But with all this mentioned, when I was standing in B&H and selecting FF body, I sad to myself D700 is definitely better camera, but I will not be carrying this tank around my neck on a weekend hike all day long
I can not do direct comparison, because I sold K10D before buying 5D2, but I think 5D2 is a little bigger and a also a little lighter then PENTAX K10D, or at least it feel lighter for some reason.
Originally posted by c.r.brown Same here, I've been unhappy with the focusing on my K10D and have been thinking of the K7 if I stay at APS-C and a D700 if FF, went and checked one out it was quite a bit heavier thatn the K10d but the focus was wicked fast and silent. I dont think the VF was any brighter, didnt have them side-by-side to verify. Hand held the snapshots were in focus where for me on the k10d they would have most likely been oof.
The LCD was nice and exposure looked good. Tried it with the 85 1.8 they had.
Definitely some things to think about.
I haven't tried the Canon 5D2 yet, I like the look of the D700 better but the large dial on the back of the 5D2 looks worthwhile. Image quality is probably a wash between the two. If the Canon is lighter I'd proabably go that route so I can use my Pentax lenses.
Also I think the D700 may be a bit more intimidating if it was pointed at you.
