Keep that light out when using the Lee filter set. This adaptor kit is a great set up. Over the years, we have used many different types of kits, but this one really is great. Keeps the glass flush allowing for longer exposers, and less light distortion.
Brand: Lee Filters
Legal Disclaimer: Takes standard 100mm filters, and can be constructed to take up to four filters at any one time. It clips onto the adaptor ring which, in turn, screws onto your camera's lens.
