Camera brands sold about 1.02 million interchangeable lens cameras with a full-frame sensor or higher in the first half of the year. During that same time frame, brands shipped 2.18 million lenses for those sensors. In the first half of the year, brands sold about 2.1 million crop sensor interchangeable lens cameras and about 2.7 million crop sensor lenses. The crop sensor category likely includes a larger percentage of beginners who only purchase a kit lens with the camera, without adding another lens to swap. Photographers using full-frame sensors – or larger, such as medium format – tend to include more professionals and serious hobbyists than the crop sensor category, which tends to have lower prices and cameras that cater to beginners.
