This Clip-In ND1000 Neutral Density Filter from Kase fits select Sony Alpha cameras by attaching inside the camera body, in front of the image sensor. The filter darkens the exposure by 10 f-stops across the entire image area, allowing shutter speed to be lengthened for added blur. It also provides added aperture control in bright lighting conditions for finer manipulation of depth of field, making it an essential tool for landscape photographers.

The included magnetic adapter allows the filter to be quickly removed or exchanged, and with the filter behind the lens, there is no possibility of a lens vignetting. It is also an ideal way to add filtration to lenses without the ability to mount front filters, like ultra-wide and fisheye lenses.
