The Nikon D7000 was designed to fall into a new class of "prosumer" DSLR cameras that have more advanced features than mid-range cameras like the D90. The D7000 has a higher resolution and several professional-level that the D90 does not have, such as dual SD card slots, weather and moisture sealing, 39 rather than 11 focus points, a 2016 segment color exposure meter, and magnesium alloy body construction. The D7000 is also more expensive than the Nikon D90 — it retails for $896 (body-only) while the D90 is significantly more affordable at $406 on Amazon.
