very high quality images for a web cam, good auto-focus and exposure compensation
I suggest users also download "Logitech Capture" software from Logitech website, if you are using this product for anything other than a conventional web cam. This software offers many, many controls not available with GHub software and really extends the usefulness of the product.
I bought one of these five years ago. It worked perfectly until recently when it quit working altogether. When the old one failed I bought this one to replace it.
