You can stop looking. Modern cameras integrate lens function tightly with the body. Each manufacturer has their own connections. You can get adaptors to physically connect eg nikon lenses to canon, but they wont auto focus, you wont be able to set aperture etc. You are fortunate that Sony kept the minolta mount alive and compatible.
the sony cameras as very good value, the 18-50 lens is worth next to nothing, just buy the camera with the most basic lens.
