This 4-stop, 105mm Heliopan ND Filter 105mm 4-Stopis an ND filter with a 16x filter factor that provides a 4-stop exposure reduction. Its 1.2 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed without overexposing your image. By slowing your exposure time, you can create motion blur for special effects or to convey a sense of movement. Opening your iris allows you to create shallow depth of field, which can help isolate your subject. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.

To prevent internal ghosting and reflections, each glass surface includes four layers of anti-reflection coating. Together, these eight coatings offer greater protection to the filter substrate and help it to stay clean for longer than with uncoated filters. This Heliopan neutral density filter is constructed from Schott glass for increased optical clarity as well as color fidelity and features a brass filter ring for enhanced durability and jamming prevention.

Q: 1. what is difference between polarizing filter model 706261 and 706262?

A: The 706262 is a slim filter, which means it's frame is not as thick. This is important on a wide angle lens, as you will get vignetting on a thicker filter.

Q: 2. How does this attach to the phone? I have a clip on ND I'm not happy with since it has light leaking in.

A: The Kase ND64 6-Stop ND Filter for Smartphones BH #KA1117130001 would come with a stick on L-Shaped Magnetic Adapter that is semi-permanent adhesive.

Q: 3. How does this compare to Hoya or Sony brand circular polarizer?

A: Heliopan is a top class brand name

Q: 4. Does this filter have front threads for attaching a lens cap?

A: Yes, Heliopan 95mm High-Transmission Circular Polarizing Multi-Coated Filter has a 95mm front accessory thread to safely attach caps or other filters.

Q: 5. How much does the filter weigh?

A: I don't have the means to weigh the filter directly. I does not weigh more than any other of the B&W filters in this particular mount. You can go to the manufacturer website for this exact product and ask the weight question. B&W Photo does not permit inserting outside links, so do a Google Search on Schneider Optics, once on the website, copy and paste the manufacturer's part number that B&H Photo includes, that will give you the specifics on this product. Then you will have links to ask the weight question of an associate. I hope this helps.

Q: 6. What's the weight of the filter Could it be used instead of the balancing ring needed for the X5S?(drone proposes).

A: Unfortunately we cannot weight any products here and the manufacturers do not provide the weight of lens filters. It may be best to ask your question on the drone Q&A itself, but we would guess that it is the same weight and could be used as a balancing ring if necessary--though it is not an exact measurement.

Q: 7. Is there a benefit to this Heliopan which costs x3 times the B+W high transmission counterpart? Thanks!

A: This Heliopan 77mm High-Transmission Circular Polarizing Multi-Coated Filter provides greater light transmission at 99.8%, which is about the same as a clear UV filter, but in a circular polarizer which usually loses much more light on average. Both filters have a brass metal filter ring. And Heliopan offers a Limited Lifetime Warranty, over the other's Limited 1-Year Warranty.

Q: 8. What's the weight of the filter Could it be used instead of the balancing ring needed for the X5S?(drone proposes).

A: Unfortunately we are not able to weigh products here, and it is not a provided specification from the manufacturer. It is recommended you contact the manufacturer for any more in-depth specifications such as this. But it is our guess that it would work very similarly to a balancing ring, though it is not an exact measurement.

Q: 9. I do not have a lot of experience with Neutral Density filters. I bought one that is a 10 stop, and I did not realize that I would not be able to see through it. So it is much more work setting up my shot. Will I be able to see through a 3 stop filter?

A: Put the camera on a tripod, manual focus then screw the the filter on carefully. Cover the viewfinder as light leaks on long exposure. Take the photo with a cable release or 2 second timerIt is for very long exposures for minute. Cool cloud effects. i doubt if you could see throu the 3 stop either. They all are for tripod use

Q: 10. I have the cannon 70D. Will this filter fits my lens?

A: It will depend on the lens you are using on the Canon 70D. This filter will fit a lens with a 72mm filter thread.
