The frame material of the clip filter is black anodized 304 stainless steel, which is non-magnetic and resistant to low temperatures. *Sony full-frame filters are firmly fixed and generally do not come off when changing lenses, but Sony APS-C filters are just resting on top of the filter, so the filter will fall off unless you turn the body upwards when changing lenses. *We recommend the focal length of the lens you use to be between 14mm and 200mm (35mm equivalent). If you use a lens with a focal length other than this, the clip filter may cause vignetting. *The optical axis will change slightly due to the installation of the clip filter. As a result, the angle of view becomes slightly wider. Please see the URL below for a list of compatible camera and lens models. https://stcoptics.com/en/clip_list/
