Hi Guys.
I will share my very prejudiced view in this.
Education is expensive, but ignorance costs even more.
I'm convinced that one would benefit greatly by stretching a bit towards a mid-range body which has more features of interest to an advancing imagemaker. Many newcomers buy entry level cameras and soon learn why they should have bought something a bit up-line. That may be why so many entry level cameras are for sale used. While this may be good for the manufacturers and dealers, it is not so good for putting the best value and performance into the hands of the new aspiring photographic student.
A sensor is important, but it does not alone make a camera. How the camera fits the hand, how large, clearly, and brightly the viewfinder looks, how easily and intuitively the controls are accessed, and the availability of accessories, photographer-centric features, lenses, and service all matter too. The length of the "trick list" does not matter.
Something like the Nikon D7000, or equivalent Canon, or better, would be in line with my thinking. Canon or Nikon because the availability of affordable accessories, lenses, and service are not in question. There are lots of lenses and aftermarket products for those brands.
One might favor Canon EOS for its short flange to film plane (sensor) distance. This makes it possible (via adapters) for Canon to mount more other-brand glass than anybody else. If one wants to (manually) experiment with lots of optics, cheap and costly, this is a great choice. Pentax comes close with their M42/K mounts, but with lesser availability of modern bodies, accessories, and service in some places.
Nikon bodies will, with minor tuning in a few cases (AI-mod), mount F mount NIkkors and other F mount lenses from the sixties and since. And there are hundreds of them. But Nikon will mount almost nothing else (allowing infinity focus) without adapters involving image-degrading corrective optics. Canon has the edge in this.
The EVF is getting better by the day, and will replace the OVF someday. Nikon and Canon will adjust to this reality, or they will soon wish they had. In the meanwhile, the mirror box with a bright glass pentaprism finder is hard to beat. The entry level dSLRs have dimmer pentamirror finders, and those entry-level cameras with EVFs have been marginal so far. A high quality finder is one of those features that a newbie does not understand and appreciate at first. But he will later.
There is no economy in swapping about on the way up to whatever we needed in the first place.
