              I can't begin to express the dissapointment I feel at the bias and plain inaccuracy of these comparisons. Not necessarily against these two that are depicted but from the Nikon 7100 down. Even while being a Nikon fan myself these reviews are comical to say the least. Any new buyer using this website as a reference to help weigh their decision on a DSLR should disregard everything this site says and look elsewhere. The representation of the "Facts" are misguiding and in some cases an absolute lie. Trust it to your own detriment.
