This 2 x 2" Tiffen 81EF ND Filter 2x2" 1-Stopblends both an amber light-balancing 81EF and a 0.3 neutral density filter. The ND filtration provides a 1-stop exposure reduction for darkening the entire image in order to photograph with a wider aperture or slower shutter speed than normally required. The 81EF filtration covers the entire filter plane and lessens the color temperature by 650K, enabling the ability to attain 3200K balance when the prevailing light source is 3850K.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between two pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. This filter measures 2 x 2" / 50.8 x 50.8mm.

0.3 Optical Density    ColorCore Technology    Warming Filter to Decrease Color Temp    ND Filter to Increase Exposure Length

Combination of both an amber light-balancing 81EF and an ND filter.

0.3 ND filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.

81EF light-balancing filter decreases color temperature and provides a warming effect.

Q: 1. Does this fit the Canon 14mm F2.8 L Mark 1 lens?

A: No, this Tiffen 48mm Rear Mount ND 1.2 Filter is not compatible with the rear filter slot on the Canon 14mm f/2.8L lens.

Q: 2. Would a 25-30 second exposure of a waterfall be possible on a partly sunny day at f/22?

A: You almost certainly need a denser filter, or double up on some NDs, unless you have an extremely low ISO. I doubt an ISO of 50 would be enough.

Q: 5. 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: 6. I want take water falls is this ND 0.9 (3 stop) capable ? for water fall? Or I need more darker ND filter what do you suggest?

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. Will this filter fit the Canon 70-200 lens?

Q: 10. 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.
