nisi launches variable nd filter without the dreaded x-effect


nisi filters has announced a new variable nd filter that, at least according to the company, does not produce the dreaded x-effect at its most extreme settings. the nisi filters pro nano 1.5-5-stop enhance nd-vario offers between 1.5 stops and 5 stop of density variation to allow for moderate long exposures for stills photographers, and reduced light intensity for videographers needing to control apertures. the ‘density’ of the filter is controlled by turning one polarizer against another, with a geared knob that turns the forward sheet of glass for added accuracy. the company also says that it has avoided the dark x-effect that many variable nd filters suffer from when used at their densest settings, but it doesn’t say how. the filter is said to enhance color too, but at the same t

canon patents innovative lens adapter with built-in electronic nd filter


a canon patent from october, 2017 resurfaced on the canon rumor mill today, and it describes something pretty innovative from the japanese camera giant. the patent shows a lens adapter—ostensibly designed for a mirrorless camera—that features a built-in variable-voltage nd filter. the nd filter component is "formed from an electrochromic device [or a liquid crystal element] which changes light transmittance on application of a voltage." that way, you could electronically and silently change the amount of light hitting your camera's sensor without stopping down the lens. as canon news points out, this would be particularly useful for video shooting, since it's silent, and it would allow you to separate depth-of-field control from brightness (i.e. shoot with a shallow depth-of-field i

moment filter mount lets you add 62mm filters to its iphone lenses


with its beautifully-manufactured metal lenses, moment has firmly established itself in the 'high-end' bracket of the market for iphone accessory lenses. and now, the us-brand is taking it to the next level by launching an accessory that'll make its products even more attractive to anyone who takes their iphoneography seriously: a 62mm filter mount. thanks to two rubber collars that are included in the package, the mount is compatible with all moment lenses. one collar has been specifically designed to hold the wide angle lens, while the other works with all other lenses in the moment line-up. your filters screw into a metal filter adapter ring, which slides onto the rubber collar. the latter then firmly attaches to your lens. the kit allows you to attach any filter with a 62mm thr






sigma can install a rear-mounted filter holder on your canon 14mm f1.8 art lens


lens manufacturer sigma has announced an interesting new service: users of the company's canon mount 14mm f1.8 dg hsm art lens can now pay the company to fit a rear mount filter holder onto their lens. the fhr-11 filter holder is designed to allow gel filters to be held over the rear element of the lens so photographers can enjoy "more freedom of expression." those who want to fit the holder themselves can buy it without the installation service, but keep in mind that damage caused by erroneous fitting will not be covered by the lens' warranty. sigma says the time the fitting will take depends on local services, but in japan users are being told to expect the lens to be away for a week. in the uk, the fhr-11 on its own costs £35 (~$45 usd), while the filter+install service costs £60






irix announces 100mm filter system for wide angle lenses


lens manufacturer irix announced earlier today that it plans to release a filter holder and a collection of filters in 100x100mm and 100x150mm sizes—a system designed especially to fit its 15mm f2.4 lens. the holder accepts a special bayonet mount adapter to attach to the front of the 15mm lens, while a range of additional screw thread adapters will allow the holder to be used with other lenses. the irix edge 100 system will consist of a dual slot holder that the company claims is the lightest in its class. the holder is made from ‘aluminium alloy’ and features a rotating joint to allow easy positioning of graduated filters and polarisers. irix says that the holder, called the ifh-100, has a profile that’s slim enough to avoid mechanical vignetting even when two filters are held in

stc adds 6-stop neutral density to its clip-on sensor filter range


specialist filter manufacturer stc optical ltd has expanded its range of clip filters to include a nd64 with infrared-cut properties. the new filter, which clips directly in front of the camera’s sensor instead of over the front of the lens, provides 6 stops of light reduction while maintaining accurate colors by preventing infrared light from passing freely during the exposure. the benefit of using filters over the sensor is that the same filter can be used whichever lens is fitted, so users don’t have to buy a separate size for each lens diameter, or a different adapter ring. these kinds of filters are especially useful when used with ultra-wide lenses as they present no danger of vignetting and they fit behind lenses that can't accept conventional front-element screw-in
