The Cokin P Series 85A Balancing Filteris designed for use with a Cokin P Series Filter Holder. It is uniform in color and with a mired shift value of +112, can be applied to purposely create a warm cast over an entire image. This effect can be obtained under daylight when this filter is used on a film camera system with daylight film installed, or on a digital camera system with its daylight white balance setting selected. The Cokin P Series 85A Light Balancing Filter is also useful for balancing light sources with a color temperature of 5500K for type A tungsten film, which is designed to accurately reproduce colors under 3400K light sources.

This filter is made of durable, optical resin (CR39). When used, the Cokin P Series 85A Light Balancing Filter's 0.2 density darkens the entire image by 0.6 stops. This reduction in exposure can be compensated for by adjusting the aperture setting of the lens it is placed on, or the shutter speed of the camera being used.

The greater the difference between the color temperatures they are designed to correct for over 3400K, light balancing filters for type A tungsten film are considered to be progressively stronger in their effect when used to add warmth to a daylight image.

Q: 3. I am interested in purchasing good quality graduated ND and reverse grad ND filters for landscape photography, perhaps Singh-Ray or equivalent. I use a Canon 5D Mk III with EF 24-70, f/2.8 (82mm) and EF 70-200, f/2.8 (77mm) lenses. In the future, I may also purchase a wider angle prime lens (say 12-14mm) for landscape work. I would like to be able to mount the grad ND filters on these lenses but am not familiar at all with Cokin or any other holders. What would you advise about the type of adapters and holders I should be researching? Thank you.

A: I highly recommend Cokin filters. I have been using them for a long time. You need an adapter ring for your77mm lens. I have a 77mm lens and a 67mm lens. I also have a 67mm adapter for my 67mm lens. Cokinfilters are much cheaper then Sing-Ray and Lee filters. Good shooting.

Q: 6. Well this be able to fit on Tamron 11-16mm without vignetting on a nikon d7000?

With the above adapter ring, the holder would connect to your lens and you should not get vignetting with this setup.

Q: 8. I have a 24mm lens that and uses a 52mm ring. Do I need an adapter ring to attach this cokin filter holder to my lens?

Q: 9. Will this holder produce vignetting with a Canon 17-40 lens on a full frame body?

A: No, you should not have an issue with using the Canon 17-40mm lens with the Cokin Z-PRO Filter Holder. The Canon 17-40mm uses 77mm filters, and would need the Cokin 77mm Z-PRO Adapter Ring (0.75mm Pitch Thread), B&H # COARZP77, to connect the adapter ring to the filter holder. The Cokin Z-PRO filter holder is large enough for lenses with 95mm filter threads, and would be large enough to prevent vignetting on the 17-40mm lens.

Q: 10. Will these hold the 85mm Format-Hitech filters? just curious since i have the Format hitech filters.
