This 3-stop, 35.5mm Heliopan ND Filter provides a 3-stop exposure reduction. Its 0.9 optical 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.

A: Yes this filter is compatible with the Panasonic Lumix S 20-60mm f/3.5-5.6 Lens.

Q: 2. What size cap will fit this filter?

A: I contacted a technical Rep with Bower, and he tried it with both a standard type 52mm lens cap, and also the newer design many manufacturers are using with the center-pinch type and both fit without issue. I'm not sure what that comment in the customer reviews may have been experiencing but it will hold a standard 52mm lens cap.

Q: 3. If I put a Moment 72mm VND filter(2 to 5-Stop) on a Sony Zeiss Vario-Tessar T* FE 16-35mm F4 ZA OSS lens, will the vignetting appear at 16mm?

A: Yes vignetting is likely to appear since Moment 72mm Variable Neutral Density 0.6 to 1.5 Filter is thick and that lens is very wide and if you are using that lens on a full frame camera.

Q: 4. 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: 5. 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
