my theory is that, once manufacturing issues are solved, Canon will have to lower the price of their 5D3 because of low sales numbers, given that the D800 is so much better for stills in nearly every image quality metric, and its price is significantly lower too
Why aren't you on a waiting list for the D-800 then?
Likely because he is just a troll or realistically does know that it will Nikon take quite some time to resolve all these issues with the D800.
I compared these 2 cams myself extensively too, out of 3 D800 I tried, in 3 different countries (UK, Germany, Spain), from 3 different production batches, at least one of them suffered from the following defects (some of which, like the left AF, all 3 showed the defect):
- strange spots on the sensor, (dirt, oil, I don't know) out of box!
- green tint on LCD, no color accuracy (officially not acknowledged by N, though obvious!)
- AWB with green tint
- outer left AF points not working, AF point pivoting
- soft focus on left side with some lenses
- scratches on mirror, out of box!
- total camera hang ups in some configs (by now there was a firmware update, but I read that it did not solve it with all cams)
- HDMI out not working with some recorders (one dealer couldn't get it to work, well I don't need that anyway, but an example for Specsheet hype vs RL)
- long exposure issues (see some blogs for details...this is really an ... for landscaping)
- liveview zoomed in is "wobbly" & noisy, useless for manual focusing
- moire issues
- LCDisplay frame rate very low (not a big thingy, but I think its the quality of the chosen LCD/Rendering solution chosen, which is just subpar)
- high video noise
- high mirror vibration, blurring pics
- Flashes are wirelessly not triggered reliably
- faulty battery
- misaligned pentaprism (basically more than 3 cams, because this was noticed by one dealer and he had a second D800...he shouldn't have told me...)
For several of these defects you'll easily find youtube videos and threads in Nikon forums discussing these too...
For me, it looks like Nikon currently has severe quality control issues with the D800.
Some of these obviously won't be solved by firmware and Nikon is not showing any(!) interest in acknowledging them (compared to Canon, who acted fairly quickly regarding the "little" light leak issue). Spoke with Nikon Germany sales on a fair again just recently too...which reduced my expectation that Nikon is going to do a lot about AF or other things I mentioned.
They consider most of the list as up to specs...
To me it looks like there are many, many more issues with the new FF from Nikon compared to Canon's... and Nikon does not seem to do anything or care about several of them (except battery issues so far, where they are basically forced to).
Put on top that, I have the impression that the German Nikon support is far worse than the Canon.
I personally move the price difference now into the category "you get what you pay for".
Oh and by the way, if I expose correct, I do not need the extra DR at low ISO, but at mid to high ISO I'm happy about the extra DR (over the Nikon), because there I probably need it more often when shooting AL...
I still prefer the Canon Skin tones and the 5D3 is more responsive than the D800.
(and there is more about the 5D3, which I prefer, but thats not subject of my post here)
So no, in no way is the D800 in IQ or other aspects far superior to the 5D3. Only for controlled light situations and tripod landscaping it is, but in real life, only in these situations, and for my taste only by a small amount. In others she is NOT.
Lesson learned: stop comparing spec sheets, but rent and go out and try/compare the cams of your interest yourself.
And stop interpreting silly sales charts of Amazon, they do not tell you what the right Cam is for you!
my 2 cents
PS I bought the 5D3 with a german warranty, plus my CPS dealer grants an extended Canon warranty to 3 years.
Again, you get what you pay for
