Another "conspiracy theory" on Nikon's marketing strategy:
"Holy cow, I just realized Nikon's big deception: the D600, D800, D800E and D4 are all the same cameras designed and produced in parallel at the same time and all have the same insides, producing the same images with the same processing power, same LCDs, same green-shift problems and identical AF controls. They differ only in exterior packaging and when Nikon chose to announce them to make them appear different."
"Today, Nikon's 2012 FX trio of D600, D800 and D4 obviously were all designed and manufactured at the same time with the same innards, and merely announced in descending cost order at different times to try to hide the simple fact that they're the same camera inside."
"What's most astounding is how they all have the same processing power. Simple technology tells us that with the D4's big battery that Nikon would put more computing power in it, but let's compare the computing power of each:
MP FPS Pixels processed per second
D4 16 10 160 MP/s
D800 36 4 144 MP/s
D600 24 5.5 132 MP/s
Yes, there's a small difference, but nothing significant. Heck, Nikon didn't even throw double processors in the D4; it's got about the same processing ability as the D600.
Autofocus? It's all the same. They all have the same stupid pushbutton replacing the real AF controls of all previous cameras."
"Firmware? The same. Same menus, same options, same everything — except that the D600 does away with the dopey Settings Banks and replaces them with its U1 and U2 modes.
LCDs? The same slightly yellow ones.
Color rendition? All three cameras are a little too green, begging us to set M1 for white balance shift. Sadly, in all three, M1 is a little too much, and M0 a little to little.
Metering? The same options. Maybe the Matrix has a few more pixels in the D4 and D800, but with over 2,000 pixels in the D600's meter, it's got way, way more than enough. They're all still based on the same 30,000 image reference as the Matrix meters were back 25 years ago. "
"Flash metering? Same. White Balance? Same. And so it goes...
"16, 24 or 36 MP is all the same. Nikon's simply varied them to segment the market. 10 MP is more than enough for anything. Nikon got the frame rate up in the D4 by reducing resolution instead of putting more processing in the D4, and put way too many pixels in the D800 to attract computer guys who love processing. Honestly, 24 MP is ideal, and we only get that in the D600. I always set my D800 down in resolution; throughput goes to pot trying to work on hundreds of 36 MP images, unless of course you're a guy who builds computers.
So there we have it all blown-open: all of Nikon's current FX cameras are essentially the same thing, put in different bodies."
Quoting Ken Rockwell. Exaggerated? Of course, that is Ken's style to inject some entertainment in his writing. There are many differences in body build which he ignored in this supposed "marketing strategy." Some truth in the sensor affecting fps with the same processing power, sure? Much truth in the commonality of many features? Yes. Still, at the end of the day they serve three different user needs and I am glad we have each of them to select from.
I would add one metric Ken didn't: high ISO lack of noise. Aren't they all about the same at ISO 3200, 6400 and 12,800? Is there really a good reason to list a higher native ISO for the D4 or was that just "marketing strategy?
As much as we love Nikon products we do have to admit the company is out to make as much money as possible by selling as many products as possible and certainly they will use some marketing strategy to accomplish that. And . . . they are not going to share that strategy with the public so we have to infer it from their actions.
Back to DX. What is Nikon's DX marketing strategy? Will all DX bodies use the same 24 megapixel sensor found in the D3200 and increase fps by increasing processing power? Or will all use the same processing power and achieve higher FPS by reducing the megapixels in the D400? Will the most significant difference really be just in the bodies (size, robustness and direct access to a few more controls)? We will see soon. It will be interesting as the D400, D7200 and D5200 should all be out in 2013.
