I am new to the Vixia line.  I recently picked up a Vixia HF R40 and I'm pretty suprised at the quality.  However, it lacks the ability to add a wide angle lens adapter.

Is there any list of Vixia HF camcorders that have lens adapters?  I would like to review their specifications and possibly pick up another one or two with the options I might be most interested in.  

thanks!
