I am getting into digital photography and have heard that the Nikon D40 is one of the best entry level DSLRs. Is this true? Is it a good camera for a beginner? Is would rather get a nikon than anything else because my buddies all have nikons (but they say that I have to buy a camera myself) and I can borrow there lens (yes I know that with some lenses you lose the AF). Also, what external flashes can you use with the D40? Also, how hard is it to develop negatives in B&W if you know nothing and have no materials? Basically starting from scratch. Thanks in advance.
