The 4 x 4" Cavision Enhanced Range ND Filter 4x4 4-Stophas a filter factor of 8x that provides a 4-stop exposure reduction and is compatible with filter holders that can accommodate 3mm thick rectangular filters. Its 1.2 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By increasing your aperture or slowing your exposure time, you can control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.

This filter is uncoated and is constructed from optical glass for clarity as well as color fidelity. Its enhanced range design is intended to maintain image sharpness when used with lenses that feature a focal length of up to 300mm.

Q: 8. Hello. I am looking to reduce my f-stop during panning shots. I do Motorsport photography and typically pan anywhere from 1/30th to 1/320. In that range, I’ve been up to f-18. I use the 300 f2.8 with both TC’s with exceptional results. My concern/question is, will this negatively affect or impact the AF system? Even though I already get a nice motion blur with panning techniques, I’d like to reduce the f-stop further to add some additional blurring in the out of focus areas. Any help here would be appreciated. Thanks.

A: This should not effect the focusing system much. If you were using anything 6-stop or more, the you may see varying results, but because it is only a 3-stop, you would be more than fine.
