What it does appear to have is a focus ring. This is normal for hyperfocal (ie. fixed focus) camera modules. The pi also had one - hence why it looks similar. You can tune the camera module for macro focus, or go for hyperfocal. This means that everything from infinity to 1/2 the hyperfocal distance is in focus. For a relatively small sensor size, this is not a problem. The advantages are that you don't need to focus, so you can take photos quicker. The disadvantage is that the photo has no bokeh, and is not pin sharp except at the hyperfocal distance. Another disadvantage is no macro mode.
I hope to be proved wrong, and the module is an autofocus module - however if it is hyperfocal that is not the end of the world
