Most studio photographers don't use medium format. However, the vast majority of people that use medium format cameras are studio photographers. They routinely need to produce poster size prints, so they need the higher resolution. Also, the bodies and lenses are large and heavy, so medium format cameras don't often get moved outside the studio, so people that don't always work in a studio often prefer something a little more portable.

- 'Full Frame' is the new 'Medium Format'.
