The thing about the D5200 is that in November it will be 3 years old, so it's nearing the end of its life cycle and should be replaced soon. The Canon T5i has already been replaced with the T6i and T6S. The D5200 has a 24MP sensor.
This gives you the ability to print larger but at the expense of having 21% smaller pixels (compared to the 700D) which should produce a narrower dynamic range than the 700D. Here's a comparison - http://www.digicamdb.com/compare/nikon_d... The difference between 18MP and 24MP will not be noticeable unless you print larger than about 11x14 which most people never do. The issue that many have once they get a camera with 24MP or more, is that the sensor has such high resolution that any little imperfection in their shooting technique becomes magnified.
I noticed this myself when I got my 40MP camera. Hand holding it was very difficult at first and I now normally use faster shutter speeds, or more often than not, a good sturdy Manfrotto tripod and a ball head. You'll need a good sturdy one with 24MP.
The old rule of thumb that your shutter speed should be 1/your focal length just doesn't apply to high resolution cameras. Most will agree that you need to double that rule of thumb, but don't forget about the 1.5x crop factor with Nikons. If you are interested in sequential shots like shooting a skateboarder making a jump, or you like to shoot sports, the 700D with its 5 frames per second (fps) shooting rate will allow you to get more shots than what the D5200 can do at a slow 3fps.
Here's a comparison of main specifications: http://www.dpreview.com/products/compare... Specs, however, are just a part of the game. You need to understand how the camera actually performs. It's like knowing the horsepower of a car but not knowing that it weight 4 tons.
What may sound great (e.g. 400 HP) is negated by the weight of the car making it slow even though it's got a lot of power. So, go to http://www.imaging-resource.com/ and read up on the two cameras to ensure that its performance will meet or exceed your needs. Since you're a landscape and nature shooter, I'd go with the D5200 because of the higher MP count.
Typical for landscapes shooters is printing large. Typical for nature shooters is cropping in heavy on distant objects like bears and moose. Both situations call for a camera with higher MP sensors.
Just be sure to shoot in RAW to have the most dynamic range available to you when you edit your images. In terms of lenses, some Canon's are better than Nikon, and some Nikon's are better than Canon. But then again, some Pentax, Sony, Olympus or Fuji's are tops too.
So I wouldn't get to hung up on which brand makes "the best" lenses either. Just be sure that which ever brand that you buy into offers (either by the name brand or by third party vendors like Sigma) the lenses that you need now and may need in the future.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
