Fairly reliable rumors surfaced today about the specs on Nikon’s newest full-frame dSLR, the anticipated D4. These come in addition to the (accurate, now-confirmed) rumors about the D800, which popped up a few months ago.

With the release of this new line of full-frame FX cameras, Nikon is redistributing their sensor technologies across product tiers in a way that departs from their approach with the previous line. Previously, the mid-tier professional FX cameras (the D700) simply featured a cheaper, higher pixel-density sensor than their upper-tier professional FX cameras. The contrast between landscape-quality sensors and low-light sensors was distributed between the two cameras in the upper-tier pro line (the D3X and D3S).

Now, Nikon is positioning the mid-tier pro D800 to carry their high megapixel, color-performant sensor, while the upper-tier pro D4 packs the high ISO/framerate sensor. I would wonder if it’s a trend the company will continue in the future, but I’m too busy scanning eBay to see if and when the price of the D3S will drop. [Nikon Rumors]
