The D4 only has 16MP... is it behind the D7000 with its 16MP? Would you take a D5100 with 16MP over a D700 with only 12MP? The D90 is just as good now as it was when it first came out.
Meh. There are many more parameters to a fotochip than just the megapixel. Such as:
- Color depth: how precisely can the chip meter fine differences between colors. The eye manages about 25 bit or so.
- Dynamic range: the eye can do 24 steps, chemical film can do 16-18 steps. My D5100 can do 12 steps at ISO 100 and thats right now brilliant for a digital camera.
- Low light performance: how low ISO values are still producing tolerable pictures ?
- Noise: Chemical film doesnt know this problem at all. How much noise is in the picture ?
- Detail: How well are fine details preserved ? Canons are known for good performance in this. In fact that seems to be the category where they are brilliant. I am not sure how this is measured though, it just appears in some magazine tests without explanation.
Interesting features:
- Eletronic Shutter: Can the chip realize extremely short shutter speeds electronically ?
- Automatic Gray filter: A feature I would like to see on future cameras: RAISE the ISO to much higher values if wanted, so grayfilters are superflous (for example to make slow movements visible on pictures).
And thats just the fotochip. The lenses add many more parameters of quality.
Keeping a dslr for 6+ years is like a baby wearing the same clothes for 6+ years

I dunno, if Nikon doesnt release their 3ccd on a chip in the next 6 years, I might still be happy with the D5100. I dont think theres much I cant do with it and getting a full frame is kind of silly for a hobby photographer like I am.
