When friends approach me for buying advice on a camera, the first thing I ask them is to consider how often they believe they’ll use it because at times, they send me links to really expensive cameras that I would never pay for if meant just taking it out twice a month. I didn’t mind paying $1,200 for my D90 when it was first introduced because my wife can vouch for how inseparable as my iPhone it has been. In addition actual usage, there’s so many other variables to consider when buying a camera, none of which I was aware of when I bought my first dSLR.
