This Series 9 Tiffen Series 9 ND Filter 2.3-Stopis a solid neutral density filter providing a 2.3-stop exposure. This 0.7 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 made using ColorCore technology, a process that involves laminating the filter substrate between two pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings. This filter is compatible with Series 9 filter holders.

Q: 3. Tiffen ND 0.9 filter dark enough for taking water fall ?

A: The best ND filter for photographing Waterfalls will vary based on the shooting conditions and the effect you are looking to achieve. By experimenting you will discover what works best for you. A 3-Stop ND filter is a good place to start. I would suggest getting a Circular Polarizer as well. A Circular Polarizer will reduce reflections off the water, and block some light as well. Here is a link where you can find Circular Polarizers on our site. https://bhpho.to/3xMEALl

Q: 7. Hi, I own a Canon 60D with the Canon EOS 18-135mm kit lens. I am wondering if this Tiffen ND filter fits my lens or not. If not, can you provide me a link of the right filter I am looking for? I need a 3x and a 6x (maybe even a 9x).Thanks-Gianluca

A: The Canon 18-135mm lens uses 67mm sized filters. This one in question is too large as it is a 77mm size. Below is a link to all of the 67mm sized ND filters we offer on our website. On the left hand side are search result filters you may select to result only ones which suit your criteria, which they do have a section to narrow down based on density.http://bhpho.to/1pBCrIB

Q: 8. Will this vignette with 7.5mm ultrawide Laowa lens?

A: There will be very little vignetting with this filter.

Q: 9. Is this filter multi-coated?

A: The answer is a qualified - NO. Tiffen filters are not solid glass likemost other filters. They are created by a special lamination process.The dyes are mixed with thinners and solvents and they applied to aglass substrate. The laminate forms an ultra thin coating that isless than 1 mil thick. A second clear glass plate is placed on top ofthe coated glass forming a sandwich. The laminate filter is thensubjected to high heat and pressure to fuse it together. Since thecoating is between the two layers of glass it is protected indfinitelyfrom any wear. The outer surfaces of the filter are not coated to myknowledge. You can scratch tho outer glass but not the coating inbetween.
