The most common question people ask when buying their first DSLR is whether to side with Canon or Nikon. Indeed, even more experienced photographers tied to one system often think about what they would gain by switching sides. 

The fact is that both companies make excellent DSLRs. Nevertheless, at any given point they each have slightly different offerings on the market, and so it follows that some models will be better suited to your specific needs than others.
