The Cokin X-Pro Hard-Edge Graduated Blue Filter 0.6is designed for use with a Cokin X-Pro Series Filter Holder. It can be used to add blue to a hazy or colorless sky. When used instead of a polarizer filter to enhance the sky within an image, the desired effect can be applied only to the sky, without any unwanted polarization or additional contrast to any part of the image. The filter is densest at the edge and tapers to clear by the middle, with a hard-edged line of transition between the dense and clear areas. A graduated filter with a hard-edged line of transition is useful for images which include defined horizon lines. This filter has up to a 0.6 density and reduces light from entering a lens by up to two stops.

This filter is made of durable, optical resin (CR39) and measures 3.0mm thick.

Q: 1. I have a Nikon d300 and a Nikon 35mm 1.8mm 52mm filter would this work with this

A: Yes it will work, but you need to buy the 52mm adapter ring to fit the Cokon filter.

Q: 2. Are the Cpkin filters in the p series 100 x 150?

A: No, they are not. The above filter, which is designed for the Cokin P-series filter holder, measures 3.3 x 3.9 (84.0 x 100.0 mm) in size. A filter measuring 100mm x 150mm in size would be too large to fit in a Cokin P-series filter holder.

Q: 3. does this kit include a medium graduated neutral density filter?

A: Yes

Q: 4. Is it exactly the same hard stop-1 and hard stop-2 ND filter in Cokin kit CH3HO25 and cokin kit CH300-02?Which party number has ND soft stop-1 and soft stop-2 in the cheaper P series? (not Cokin Nuances P-Series)Thanks :)

A: The filters in both B&H # COCH3HO25 and B&H # COCH30002 are exactly the same. The difference being one set has the holder and the other does not. Sorry, there are no soft edge P series filers that are not Nuances.

Q: 5. Is this a hard grad ND filter? I believe it is from the description but wanted to check. My instructor urges me to buy a 2-stop or 3-stop soft graduated neutral density (grad ND) filter. If this is not the right one which one do you offer for the A series of Cokin filters?

A: Yes, this is a hard graduated ND filter. The soft 121 Graduated ND filter by Cokin is designated as such with an S after the number, so you are going to want this one: http://bhpho.to/1hwdrCw

Q: 6. Is this hard or soft edge?

A: The progression is graduated from the middle of the sheet to the top. This modest graduation can be seen on an image of the filter on the Cokin website.

Q: 7. Will the Cokin P-series filter holder fit my Rokkor MC W. and MC macro lenses?

A: As long as your Rokkor lenses have a standard filter thread between 48-82mm, and a focal length longer than 20mm, you could use the regular P-series filter holder with your lenses.

Q: 8. What is the difference between the Cokin P121 and the P121S graduated neutral density filters? Both are stated to be 3-stop graduated filters. Does the s version make a more gradual transition from clear to dark than the base 121?

A: The S version is a softer graduation

Q: 9. will this work on my A7II lens?

A: While it should be compatible, the answer will depend on the lens you own, not which camera you own. As the Sony Alpha a7II Mirrorless Digital Camera uses interchangeable lenses, we would first need to know which lens you own (or the filter thread size for your lens) to see if there is an adapter ring compatible for your lens' filter thread size. As this was not listed in your inquiry, I would have to recommend to e-mail us the brand/model name of your lens, the B&H number, or the filter thread size of your lens to prophoto@bhphotovideo.com and we could then inform you if the system would work with your equipment, and which lens adapter ring would be required for purchase to use the filter holder system with your equipment.

Q: 10. Does the filter holder rotate like the Lee system?

A: Yes, the Cokin Z-Pro holder rotates.
