My basic question is, What did I do wrong that my resolution is low. Is it my camera, lens choice, size of print? I'm frustrated that I can't get a crisp poster of this size with my D7000. I want to upgrade to the D750 but I do a lot of work for this school, about 12 different sports for them a year, Will the D750 do better? I know that the 35mm lens would have been a better choice but I'm trying to upgrade as I go.... I feel like I'm comfortable with photography until I get to issues like this.
