Nikon D50 vs Nikon D80 — one reason why this is still such a hot topic for debate is because the D50 currently represents the best bang-for-the-buck Nikon digital SLR system … we’re talking about approximately $480 to $530 for the Nikon D50 kit which includes the Nikkor 18-55mm lens, depending on how good your bargain-hunting skills are.
The dilemma comes in when you consider that the D50 is $300 cheaper than the D80 … it can get a bit mind-numbing deciding whether you need the extra megapixels and features in the D80 to justify the additional expenditure. In many cases, the D50 in the right hands can take astounding pictures, but on the other hand, there are those who (like me!) need to always get the latest and greatest, within reason.
