The 6700M (ILCE-6700M) is a Sony APS-C mirrorless interchangeable-lens camera kit, not a lens or a full-frame camera.
It is part of the Sony Alpha 6000/6700 series and comes with a bundled zoom lens (that’s what the “M” usually indicates). The camera features a 26MP APS-C Exmor R CMOS sensor, advanced real-time autofocus with subject recognition (humans, animals, birds, vehicles), strong 4K video capabilities, and in-body stabilization. It is designed as a compact but powerful hybrid camera for photography and video creators, offering high performance for travel, wildlife, vlogging, and everyday professional use in a smaller body than Sony’s full-frame Alpha series.
