Compact camera modules that may be used in small form factor devices. The camera module may include a lens holder configured to receive one or more lens elements and a photosensor. In some embodiments, the lens holder may define a first recess for receiving the lens elements and a second recess for receiving one or more other components, such as the photosensor. In some embodiments, the photosensor may be configured to communicate with a flex circuit board without coupling the photosensor to a substrate to form a flip chip that communicates with the flex circuit board. The photosensor may be optically aligned with the lens elements and bonded to the lens holder such that the photosensor is fixed in an aligned position and at least partially enclosed by the lens holder.
