Various embodiments include an interlock arrangement that may be used to attach a lens barrel to a lens carrier of a camera. In some embodiments, the interlock arrangement may restrict movement of the lens barrel relative to the lens carrier along at least an optical axis. In various examples, the interlock arrangement may include one or more grooves and one or more protrusions. For instance, a groove may be defined by the lens barrel or the lens carrier, and a protrusion may extend from the lens barrel or the lens carrier to at least partially into the groove. In some cases, the interlock arrangement may include an adhesive that at least partially fills gaps within the interlock arrangement between the lens barrel and the lens carrier. According to some embodiments, the interlock arrangement may include one or more recesses that provide inlets for the adhesive to be introduced to the gaps within the interlock arrangement.
