1. More focus points. When using auto-focus, the D7000 will have an easier time focusing on what you want it to focus on. The D5100 has 11 and the D7000 has 39
2. 60% longer lasting batteries.
3. Faster continuous shooting. If you’re into shooting sports or any fast-moving subject, continuous shooting allows you to capture multiple images in a single second. The D5100 shoots at four frames per second whereas the D7000 shoots at six frames per second.
4. Weather sealed. This means you can shoot with the D7000 in the rain.
5. Two memory card slots. This is really a cool feature. The D7000 has two memory card slots which means you’ll be less likely to find yourself standing in front of a gorgeous scene with no more memory left.
6. Faster shutter speed. The fastest shutter speed on the D5100 is 1/4000th of a second; on the D7000: 1/8000th of a second. This would be good in, say a nuclear detonation or a nice shot of the sun,
Advantages of the D5100 over the D7000:
1. A flip out screen (handy if you want to put your camera anywhere but at your eye level and be able to see what your camera is about to capture before you shoot it) Great if you are in a crowd.
2. Smaller and lighter: The D5100 is 10% smaller and 30% lighter than the D7000. Weighing in at only 560 g or 1.23 lb/19.75 oz. zThis is something to consider if you plan on carrying your camera around with you all day
3. Less expensive so you can spend more on your lens! First of all, it’s important to understand where the D5100 fits in Nikon’s capabilities.
The D5100 is considered a “high-end enthusiast” D-SLR which means that it shares the same image sensor as the high-end D7000 without some of the higher-end features. The D5100 offers almost the same image quality as its bigger brother in a less-expensive, smaller package, while adding a few tricks the D7000 doesn’t have including an articulating display that helps you frame hard-to-reach spots. I consider the Nikon D5100 the best camera I have ever used.
A nice “bonus” feature is that the D5100 can use old manual focus lenses – even the non-AI models. They can only be used in Manual exposure mode of course. You will have to use an external meter to calculate exposure (or use the histogram information in the photo playback to check exposure). If you don’t mind using classic, old-school photography techniques, lenses like the 50mm f1.4 and 55mm micro Nikkor can be picked up at a very low-cost
