Nikon D3100 VS. D300 VS. D700

For the cost of this camera, I don't think you can get anything better. The low light performance is off the charts. As a wedding photographer I regularly shoot with Nikon's high end professional equipment and I was amazed how close this camera is to a pro camera. Now let me get specific. In order to compare I took a look at 100% files out of each camera I own.

Which camera excels Nikon D3100($Cheap) VS. D300($1600) VS. D700 ($2,700):
* Lens = The D3100 is the only camera that comes with a lens at it's normal price
* ISO Performance = Tie between D3100 and D700! (It could be Nikon's new processing but the JPEG looks fantastic I was shooting D3100 on 6400iso with very little noise at all)
* Low Light Focusing = D700
* Focus Speed = D700
* External Buttons & Controls for Pros = D700
* Menu Navigation = D3100
* Ease of Use = D3100
* Megapixel = D3100 (14.2)
* Sensor size = D700 (Much more important than megapixels but I won't get into this)
* Can use older lenses with functionality = D700 & D300
* Video = D3100 of course! 1080P video looks amazing.
* Frame Rate = D300 at 6 photos a second
* Weight = D3100 (light as a feather)
* Ergonomics = D700 (big enough for all my finger)

Lens:
The lens is a kit lens, it will work outside but not so great in low light. The Vibration Reduction will help indoors but Vibration Reduction can't stop a child or pet in motion indoors. Consider buying a 35mm 1.8dx AFS for around $200 and you will be super happy with this camera.

Video:
I purchased the 3100 specifically to shoot video, so I put on Nikon's brand new 85mm 1.4g Nano lens and shot video with it. The lens costs more than double the camera but I wanted to see how the 1080P video looked. It has the look of a cinematic movie. After the 85mm, I put on Nikon's 50 1.2 manual focus lens and was able to take very cinematic video in manual mode. In order to make it brighter or darker you either need to use a really old lens like the 50mm 1.2 and hit the AE-L (auto exposure lock) and twist the aperture to change exposure. Or you can hit the AE-L button when you get the exposure you like. Its not a perfect system but it works well for me. Inside the menu options you can change the AE-L button to hold the setting until you reset which is helpful.

Jello Cam (What's not so great):
This camera still suffers from the "Jello Cam" look in video if it is not on a tripod and you are shaky. The video can look like jello if moved too quickly. Use a monopod or tripod when shooting to avoid this. I'm not sure if a faster video frame rate 60fps would help - but at 24 and 30 it can suffer badly.

Conclusion:
This is an amazing deal! Unless you make most of your income from photography or have a stockpile of old lenses (this camera can only autofocus with AFS lenses) then this camera is the must have camera of the year. If you have good composition skills and an eye for light you can take photos worthy of a magazine with this. Seriously, you won't regret buying this camera. When you do, do yourself a favor and buy an additional Nikon AFS lens that has a maximum aperture of 2.8, 1.8 or 1.4. These lenses will take better portraits and deal better in low light than the kit lens.
