Heliopan 707790 overview

  • 1Description

The Heliopan 77mm Variable Gray ND Filter is a solid variable neutral density filter providing a reduction of about 1 to 6 stops. The 0.3 to 1.8 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. The degree of density is easily controlled by rotating the front filter ring, allowing you to previsualize the additional exposure length required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image.

This filter features a brass mounting ring that is painted matte black to help reduce reflections. High quality Schott glass provides optical clarity and greater contrast to help render scenes with greater fidelity and resolution. This filter does not have front threads for attaching other filters.

Variable neutral density filter allows you to dial in differing amounts of density scene to scene.
0.3 to 1.8 ND filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.
Providing a reduction of 1 to 6 stops, this filter allows you to control depth of field and convey movement more easily.
Filter does not affect coloration of the image.
Matte black brass ring reduces reflections and improves durability.

Heliopan 707790 reviews

77mm Variable Gray ND Filter is rated 3.6 out of 5 by 12.
Rated 1 out of 5 by from No front thread - Cannot attach a hood! I have a LCW Fader ND II I use for video. I found it was softer than I liked. After all the glowing reviews of the Heliopan Vario I decided to purchase the 77mm version. I also purchased a 77mm lens hood to attach to the front of the Heliopan. Upon arrival I was surprised to see the Heliopan has no front thread so I cannot attach a hood. What gives? I made the decision to buy the Heliopan and hood rather than a matte box and 4x4 filters. Now I'm back to the drawing board. The Heliopan is going and I will buy a matte box and 4x4 filters. Considering the price of the Heliopan I'm extremely annoyed!!

Rated 5 out of 5 by from I love this filter! I use this filter for multimedia work so I only have to carry one ND filter and can simply rotate the front to change the density. My favorite part is the built in stops. I've used other fader / variable ND filters that just spin and spin like a normal polarizer filter. With this filter you know when the filter is maxed out on either end. Perhaps the person in the previous review with the x-photograph had a faulty filter without proper stops. I also like that this filter has the same front threads allowing me to use the same lens cap. That's not the case with some filters, such as the Genus, which has a larger front. This also means you can't use your lens hoods (at least on the Canon 24-70 and 70-200 L lenses) with the Genus, but you can with the Heliopan. The ability to use my lens hood is invaluable, as I often work in harsh conditions, blocking not only the sun, but also dirt from motocross tracks, paintballs, etc. from my lens. I compared the Heliopan, Singh-Ray, and the Genus Filters for both sharpness and flare blocking ability. Photographing a test target (tripod, shutter release, mirror lockup) I found the Heliopan to be the sharpest, with the Sing-Ray being very close. Both easily out-performed the Genus. The Sing-Ray did the best job at blocking flare, with Heliopan in second, and Genus in last.

Rated 3 out of 5 by from Cheap packaging, questionable quality. Both times I ordered this Variable Gray ND Filter by Heliopan, the packaging was beaten up, and even a part chipped off on the second shipment. I ordered it twice because I thought the first time I was receiving used goods, by the look of the package. The second one arrived in packaging of similar poor condition. The condition of the packaging caused me to question the quality of the filter inside.The filter, though of hefty weight, is not the most quality-controlled piece of equipment I have come across. There are different tensions experienced when spinning the filter lenses to adjust the filter power. For instance the filter loosely turns at the lightest ranged of power on my filter--the two lenses actually rattle a bit against each other!--but as I get to the darkest end of the light filtering power, the tension between the lenses, on turning them, becomes so high as to be able to unscrew the entire filter from the end of my camera lens. These findings are disappointing given the over $price of the filter.My use of the product: I use the filter to enable my aperture to remain open so that I can retain a shallow depth of field without having to increase the shutter speed. This is important in my use of my 5DMIII as a video camera (keeping the shutter speed at 50 for that attempted filmic look).

Rated 1 out of 5 by from Convenience 5 Stars, Overall 1 Star I was hoping this filter would be a valuable asset as the convenience would be superb. I need a filter to allow use of fast lenses in bright conditions, depending on the ambient light the amount of neutral density varies from 1-4 stops. The convenience was great but the negative aspects of this filter were too great. Firstly the filter arrived in filthy condition, dust on the glass surfaces but more importantly there was haze on the inner surfaces of the two polarizers. An impossible situation to remedy unless I could disassemble the filter, clean it and reassemble to original correct alignment. This is exactly what I did as Heliopan doesn't appear to lock their retaining rings very well, it was screwed down loosely and could be removed without any damage to the rings or polarizers. Reassembling required proper placement of the polarizers but this was not difficult. Once cleaned and aligned I was able to evaluate the images and found too much image degradation for my taste. I called the distributor and asked some questions about the filter and was told the individual polarizers are not multicoated. I would think it would be a better product if multicoating was present, four glass surfaces, internal reflections etc. might be contributing to the image degradation. With a little help from the internet I was able to learn that this setup is a circular polarizer in the rear and a linear polarizer in front. I was then able to construct my own variable nd filter from polarizers I already owned. Although suposedly inferior filters my setup resulted in the same degradation of image quality as the heliopan, no better but no worse. I ultimately returned the filter fearing it would fall apart in use and poor image quality, and I ordered the 4 stop Heliopan ND. I consider Heliopan filters the best available but not this one. Purchase this for convenience but realize image quality will suffer.

Rated 4 out of 5 by from Fantastic build quality I bought this to use with my Canon 100-400 L telephoto lens, using it for motorsports photography to be able to get the f-stop down while using slow shutter speeds on a bright sunny day. I tested it out at 400mm and the image was ok, but there a slight bit of softness being introduced. For me this was not what I was expecting for a $450 variable filter, thinking this was the best you could get. I started out with the Light Craft II and that was atrocious with this setup (like putting Vaseline on the front of the lens) so that went back. Now I am sending this one back as well and going for a single ND 1 and 2 Stop filters from B+W hoping this will improve image quality. It did allow me to open up the aperture, placing the background out of focus (shallow dof) while panning on slow shutter speeds of 1/30th to 1/500 and up. Just not up to snuff based on the price tag. On lower focal lengths I think this filter would be great, but for longer telephoto lenses the IQ loss is visible, specially if you do a before and after. If the two .3 and .6 ND filters work out this will be about half the price of this filter and the quality will be better IMO. There is just a lot this filter has to do in order to get it to be variable, so the less glass there is between your lens the better. The front end of the filter is very narrow so you can't mount the lens cap on it as well leaving this very pricy filter exposed. And if you plan on using it with a hood, it makes changing the ND stop difficult.

Rated 1 out of 5 by from I would give this one a miss I was really disappointed with the this product. As I increased the ND effect an obvious cross-pattern artifact appeared on the images. So much that the filter was only usable to about 3-4 stop of ND effect. I returned the product to B&H without a problem and they were fantastic.

Rated 5 out of 5 by from Complete set of ND filters in one Very well build high quality ND 0.3-1.8/2.0 1-6/6.6 stops nd filters. The ND degree is well marked with smooth transition full stop at the min/max points.There are two versions for this filter 0.3-1.8 6 stops and 0.3-2.0 6.6 stops. Still waiting for B&H response for sending me the 0.3-1.8 version when my order was for the 0.3-2.0 one.Combined with 58-77mm and 67-77mm step-up rings (also by Heliopan) I'm covered for all my lenses and a wide ND range.

Rated 5 out of 5 by from Spacesaver Take out all those other filters and replace them with this beauty. I first was skeptical but this filter has proven itself time and time again. Screws on very easily and adjusts to the right density by rotating the outer ring. the only problem I found was trying to remove it from the case . Heliopan made an excellent filter. I use mine with my 28-300 lens, 77mm and have plenty of extra room in my camera bag. It's hefty enough and weighs in , so you know you won't drop it in handling.
