You did notice the first past of my reply right? The part where I ask how much does he want to spend. This has nothing to do with whether he is a beginner or not but only with what his budget is. Second, you make an assumption about what he will or will not be able to handle. Not sure about you but where I come from people are outfitted with this thing called a brain. It allows them to read, understand, comprehend, learn, etc.. So figuring out a camera should be pretty straight forward. You are pretty presumptuous with a person you don't even know.
You are absolutely right... hence my question to you. Now, if you would have read the OPs question correctly you would have figured out how much he has to spend as he clearly states that his options are the three cameras listed. Also considering he is still in school your suggestion is pretty far fetched. Also considering that he gave options for both brands, you can deduct that he does not own a DSLR now or that he is not yet attached to a brand. Again, that assumes a kind of beginner together with the overall picture. and the D3XX series is of course marked for a beginner.. right? that's why they are listed as beginner or even enthusiast cameras.
But yes, you are absolutely right, i need to check my facts and be less presumptuous and next time will follow exactly your suit. Because what I have must be what others need.
