Hoya 52 mm Pro ND 1000 Filter

Review of Hoya ProND1000 Neutral density filter: - Hoya ProND1000 is a 10 stop filter. I measure 10.3 stops in the green channel - Hoya ProND1000 is *extremely* color-neutral: A very small red cast is measurable, but not visually obvious (more below). - No discernible Infra-Red leakage / IR pollution. - Typical, decent quality aluminium frame. - Good price for performance. Safety: This is NOT a filter for photographing the sun. ========================================== - If you want to photograph the sun, use only a filter designed and certified for photographing the sun. - Solar filters have heavy IR and UV reduction, as well as high attenuation of visible light, to prevent damage to eyes or equipment. - Contact your local astronomy society, or university astronomy department for advice. Colour: ====== I've attached images of a ColorChecker chart, with: 1) Hoya ProND1000 filter 2) No filter 3) SRB ND1000 filter - These were all taken with a fixed "UniWB" white balance, which gives all images a strong green cast (the point of this weird white balance is to make it easier to check RAW exposure). - The filtered images were taken at 6", f/4. The unfiltered image was taken at 1/200 ", f/4. - The loss of focus in the filtered images is down to my sloppy technique with an extending zoom lens, the short object distance to the colour chart (~0.6m), and the wide-ish aperture (f/4). The lack of sharpness should not be attributed to the filters. The Hoya ProND 1000 is very neutral. Under Halogen lighting, I measure a very small red cast: Red up by 1.5%; Blue down by 0.25% (relative to green). The measured cast varies a little with lighting. If you are worried about this level of color cast, you should also be worrying about the color casts introduced by changing lenses. These shifts were measured on Nikon D7200 using RAW - i.e. linear light - data extracted using RawDigger. In comparison, It's quite clear that the SRB ND1000 has a blue cast. On the Nikon D7200 I used, Blue is up by about +20%, Red is down by about 30%. But the color shifts are fairly even across the different patches, so white balancing, either by setting a custom WB in the camera with the filter attached, or by adjusting the color temperature in RAW processing. The SRB has just a little difficulty with the lime-green patch on the third row, which is (relative to other patches) shifted slightly to yellow. The colour shifts quoted were measured under halogen lighting. I get similar results under high-quality (CRI Ra 98; CQS 95) LED lighting [Philips ExpertColor 4000K]. Construction: ============= Decent aluminium construction. Brass, with a knurled ring for better grip would be ideal (Like Breakthrough Technology X4 filters). Sharpness & visual artefacts: ============================= I have seen images ProND1000 images with halo artefacts perhaps related to reflections between sensor and filter. On Nikon D7200, I haven't been able to reproduce such artefacts: I've tried photographing lights, shining a torch at the filter out of frame. I've also seen reports of sharpness problems with the Hoya. But pixel-peeking with and without the filter shows *I*'m getting very sharp images, with no significant loss of detail, even inspecting images at 200%. I'm not aware of vignetting problems, except with Nikon 10-24 at 10mm at the extreme (<100 pixels) frame corners, which are down ~1/3 EV - seems like filter ring shading. I'm mostly using the Hoya with Nikon D7200 and Sigma 17-50 f/2.8 OS, at near 50mm and f/5-f/8. Usage: ===== - Autofocus may - or may not - be possible with a 10-stop filter fitted to your camera, depending on your camera, and available light. Some experimentation with live-view autofocus, and, for DSLRs, with TTL phase-detect auto-focus, is required. TTL phase-detect auto-focus may work well, but the problem is it may be hard-to-impossible to see what you are focussing on, because of the dark viewfinder relative to your environment. - A typical technique is to focus the camera without the filter, either manually, or with autofocus, and then attach the filter. Some care is required, particularly with extending zoom lenses, not to upset focus. Plate filters in a filter holder are better in this respect. There is a small focus shift on adding a filter, but negligible except for macro photography: the focus point will shift away from the camera by roughly 1/3 of the thickness of the filter glass - typically less than 1mm. - Possible difficulties in focussing suggest the use of small (ish) apertures to ensure adequate sharpness: say f/11 (full-frame); f/8 (APS-C); f/5.6 (Four Thirds). Significantly smaller apertures (higher f-numbers) will cause a loss of sharpness due to diffraction. - On SLRs, use the viewfinder blanking plate to prevent stray light entering the camera via the viewfinder. With a 10-stop filter, not much stray light needs to enter the camera to ruin a photograph. If you've lost the one that came with your camera, inexpensive 3rd-party replacements are available for popular camera models. On some camera models, you may get away without the blanking plate. I have tried and failed to provoke my D7200 to misbehave when using a 10-stop filter - for example by shining a 1.5W single-LED torch into the viewfinder. - Fitting *any* filter increases the likelihood of ghosting and flaring: Use a lens hood or matte-box to shade the filter and lens from stray light. Alternatives: ============= SRB ND1000: Moderate, correctable, blue cast; similar construction; half the price (roughly). Breakthrough Technology X4 Neutral Density 3.0: [I haven't tried this] Fairly neutral; low vignetting; Excellent construction; double the price (at least).

Recently taken delivery of this. On a 700d crop sensor camera I can use the filter on a 77mm thread canon 24-70 and (with a 77-67mm adapter ring) a 67mm thread canon 10-18mm stm lens without any vignetting / obstruction at all. I'm sure other lenses will be the same. The ability to use the filter with the 10-18mm stm lens really surprised me as 67mm filters screwed direct to the lens are visible in shot at the 10mm end and vignette to varying degrees at the narrower angles. I've had a good look at the images today and the shift in colour balance (when using Auto White Balance) is minimal to negligible (in the conditions the camera appeared to render slight inconsistent / different results in AWB mode whether the filter was fitted or not and so this may have been due to the camera and conditions). When selecting the White Balance either on a custom or one of the presets (I used Cloudy and direct sunlight) the difference in colour shift with / without the filter was negligible if noticeable at all. This was backed up by the camera's RGB histograms when reviewing the images. Also, reviewing the images at 100% zoom there was neglible, if any, change in sharpness in the images with / without the filter that I could see. In the conditions tested I would say use of the filter resulted in a difference of between 11 to 12 stops according to my 700d depending upon the composition of each shot. I still have concerns over the longevity of the surface treatment on the lens given other reviews I've read however for now I'm going to give it five stars. Having used other ND filters of varying qualities I'm v. happy with this thus far and would recommend buying it.

Bought this filter for landscape photography for long exposures of moving water. Allows for slower shutter speed to capture movement, say in a situation where normally you would need a shutter speed of a 60th of a second this filter would allow you to open the shutter for a full second. Obviously you need a tripod or solid surface to place camera on also to prevent blurring of image. Also would allow you to use a larger aperture and get a shallower depth of field The digital multi-coating is supposed to reduce the appearance of lens flare and ghosting. I find this is enough to capture the movement and when taking photos at sunset when light levels were lower I was able to open the shutter for 45 seconds or so using this filter. In bright midday daylight however it's not quite strong enough for that and if you want really long exposure times in bright light I would suggest getting a stronger filter. However as a multipurpose filter this one is perfect and can be used in a variety of situations, ideal if you don't want to go shelling out for a full range of filters

Its a really sturdy ND filter. Its 1.8 Stops which is really helpful in sunny day. I did a little bit of pixel peeping with it on on my 70d and canon 70-200 f2.8 II IS. The filter boost a little bit the contrast, the blue and red. But its really not noticable unless you do it with color checker. Would definitely buy the other version like nd16 or nd8 when putted on sale

Fidèle à eux même Amazon sont les meilleurs pour avoir tout les articles et en moins de 72h à domicile.

Bought this as a present. The recipient is very happy with it. At 4 stops, she is still able to clearly see to frame the shot and the camera has no problems metering through it. But it still is enough for things like waterfall shots.

El filtro ha llegado como se puede ver en la imagen pero por suerte solo la caja esta tocada, el filtro está en perfectas co di iones, y por eso me lo he quedado. Tenía dudas sobre pedir un nd16 o esté nd8 y me alegro de haber escogido este nd8. Lo uso con una Sony a6400 con un objetivo Sigma 16mm 1.4, para vídeo. La calidad del filtro es brutal, se nota la calidad japonesa. El filtro no produce viñeteo, ya que es un filtro fijo y eso pasa solo con los graduados o con los de muy mala calidad. El color de la imagen no se ve afectado, no sufre ningún tipo de modificación. En definitiva es un muy buen filtro de una muy buena marca. No es barato, pero la calidad cuesta. Ahora estoy mirando un filtro polarizador, por supuesto de la misma marca.

Un ottimo filtro ND 32, che permette esposizioni lunghe anche durante le ore di luce diurna. Secondo me è l'ideale nelle ore vicine all'alba/tramonto, quando la luce non è eccessiva. Di giorno 1-2 stop in più possono essere necessari per ottenere esposizioni di alcuni secondi. Attenzione perché se combinato con un altro filtro (ad es. un polarizzatore) su un obiettivo grandangolare (es. 24mm) si ottiene una leggera vignettatura sui 4 angoli, dovuta allo spessore eccessivo dei filtri che vanno quindi a creare un'ombra. Per il resto molto buono. Resistente, si pulisce facilmente. La confezione è ottima.
