The MK-VF2 viewfinder is well worth every penny I spent for it. It can be very securely attached to the camera. It has a diopter adjustment. A 3X magnification that makes focusing when doing macro photo's a snap. The comfortable eye piece can be adjusted to the left or right eye. The back half can be tilted up so your view screen is in a shadow if you are a bright ar4ea. I highly reccomend this item.
