The 5D having lesser build quality than the D200? You must be kidding (or just do not know).
In what way is the metering of a D200 better? And since when its the rather appaling AF of the D200 better than the excellent AF of the 5D? How is the 5D not durable? What is wrong with the materials used in a 5D? And since when is it twice the price of a 200D?
Sounds like FUD in the way MS fans like to put down Apple products.
The 5D is of excellent build quality, its image quality is way above that of the D200, its AF system is better, and only people who need to be making photos in streaming rain need a weather sealed camera (and that are not many, I can tell you).
What you should do is actually use a 5D sometime. You then will know what a well made and fast and accurate (AF) camera it is. And how good its image quality is (and how dynamic).
Nikon has nothing comparable to the 5D, simple as that. Yes, not everybody wants full frame. I know that. But that is why Canon also has a 30D. For when you do want the extra tele reach, or do not want the added expenses.
The upgrade to the 5D is just a natural one, the 1D will move up, so the 5D can move up too in resolution. What else is new in camera land.
I've played around with a 5D before in stores on a number of occasions, the build quality between that and the D200 is night and day - I'd suggest you open your eyes a little to other companies before tagging yourself as a hypocrite and comparing me to some MS troll.
Everything is different, from the location of buttons, to the way that they are constructed (textured, molded buttons that fit the contours of the camera, versus little cheapo glossy plastic dots that canon likes to call buttons.) Um, Inset status LCD screen to prevent scratches? Included screen protector for main LCD? Or the fact that the status LCD is significantly larger on the D200, and displays more information (as does the viewfinder.) The battery gauge on the 5D has TWO STEPS. D200 has 5 step on the status LCD, percent remaining, and charge cycles / life in the menu.
D200 has multiple programmable shooting modes, custom modes, menu layouts, etc.
Anyways, back to construction - for $3k Canon doesn't even give you a spring-loaded CF door? Nice. I get that on a D40. I'm just saying, for you money - fit and finish goes MUCH further with most Nikon cameras. A number of the features I listed already can't be found on anything less than a 1D.
D200 has an internal iTTL (wireless) flash commander and speedlite, um..
I'm really not sure how you can possibly call the AF of the D200 appalling. Pretty much proof that you've never used the camera, or at least have no idea HOW to use a camera. I've shot with D200s in every imaginable condition from monsoon-like dark, rainy days shooting equestrian sports with subjects moving at 35mph getting tack sharp continuous AF, to low light / blackout conditions at night. I've never had a problem. Period. It's almost as good as the CAM2000 in the D2Hs / x that I've also used, which is one of the fastest systems on the market. Additionally, the D200 also has an 11 point AF grid versus 9 of the 5D, and has bunch of other features from closest-subject priority, 7-area wide, groups, etc (with variable target lock-on, tracking modes, etc.) The 5D is pretty much a studio camera, sports shooters like myself that need the 1.5x crop demand much more from an AF system. The working range of the D200's AF is -1 to +19 EV, versus -.5 to +18 EV of the 5D. I mean, were you pulling all of this out of your um.. ? ..well I have no idea where you get off calling the D200's AF appalling, unless you're saying the 5D's is even worse.
On to the metering. Nikon 3D Matrix II Metering is pretty much known around the market as being the best.
Compare the 1005-pixel 3D / color system in the Nikon to the 35 segment system in the Canon. Go ahead haha. The working range of the Nikon's AF is a full stop higher, working from 0-20EV versus 1-20 of the Canon's.
What else.. let's see. Dynamic range. I'm seeing both cameras at 8.2EV usable DR. I'm on a roll here.
So, not doing very well so far - the D200 is also compatible with just about any Nikkor lens ever made, versus EF mount for the 5D.
It's also faster, buffers almost twice as many RAW files in continuous mode, USB transfer rate is more than TWICE as fast as the 5D, shoots 5fps, supports GPS EXIF tags, has a higher capacity battery, embedded image comments, user memories, programmable function buttons, more than twice as much EV compensation possibilities (+/- 5 versus 2 for the 5D.)
I mean, I could go on forever. I didn't pick a camera then become a troll trying to convert everyone - I started out with nothing, and went with Nikon for a reason.
The funny thing is - after reading all of what I said, you'd think Canon would keep the 5D in a competitive price range with the D200. Regardless of what you think, street price of the D200 is almost half that of the 5D. Kbye.
