Thank you for viewing. This is the RICOH external mini finder GV-2. It is compatible with cameras like the GR series. It's a small optical viewfinder that attaches to the hot shoe. It supports a 28mm equivalent (35mm equivalent) angle of view. The field of view is approximately 85%. The items for sale are the product and the dedicated pouch. There is no box or instruction manual. I purchased it myself and have kept it stored at home since then.
