and this filter will last a long time with better gas mileage thank you edward

I have used a few Hoya filters of different types for a long time and achieved satisfactory results. Most of the work for which I use these does not involve results that would be strongly affected by minor variations in filter parameters. This most recent purchase has been examined, quickly exposure tested, and added to the photo bag. There will not likely be any future exciting results to report unless some important photo turns up with major issues related to the filter or it falls out of its mounting somewhere in the field! It will likely be used for relatively benign tasks like photographing waterfalls.

I bought this filter to use for long exposure photography with my Nikon D600, as well as being able to use wide apertures in bright sunlight. As long as you stay within the marked limits of the filter, it works as advertised and produces great results. Colors seem to be unaffected, but some minor post-processing adjustment may be necessary to get the photo to where you want it to be. I expect this is normal.What's great about it is that it is easy to use. One short twist and you go from light to dark or dark to light. There is no need to remove the filter to re-adjust focus the way you'd have to do with darker filters. Just twist it to its lightest setting and you can see through the viewfinder. (Maybe a different story if you're trying to use live view)The clarity is very nice and photos come out sharp.This is nearly a perfect and very convenient product EXCEPT.... there may be some cases at its darkest setting where you may see some uneven exposure or vignetting. Instead of the vignetting being visible in the corners, it may appear in the top and bottom middle of the frame. You probably won't notice it at all if you're shooting longer exposures in less available light (I didn't), but if you're using it at its darkest setting in bright daylight, you might see it.To be honest this filter is not dark enough to use for long exposures in bright daylight, so this may not be much of an issue. For that you'd have to go with a 1.2 or darker filter anyway. When using this filter, make sure to always stay within the marked limits. If you try to go beyond that at the darkest setting, you're going to see a giant, dark X across your photo. There's nothing to stop you from twisting the filter 360 degrees, so just pay attention to the markings as you're rotating it.Overall I would recommend this product for its clarity, ease of use, convenience and construction. It produces great results when used correctly. If you want to do long exposures in bright sunlight or directly into the sunset, you'll need something stronger than this. Otherwise it will work well even during the day with shorter exposures.

2015 vw tiguan. always replace your crappy oem air filter with kn. Very easy to do. Better filter, more air flow, cheaper in the long run. Seller was very fast with shipping.

This filter is a big improvement over OEM and other aftermarket filters.Less airflow restriction with OEM level of filtration is the best combination you could ask for!Easy to clean and re-oil and put back into use for a LONG time!You will save a ton of money over the life of this filter in your vehicle!

This filter is awesome, lets me take long shots during the day and these pictures are coming out great! A++.

The filter is in the upper end of those I have used before, but has a strong tendency to red shift the photo at the darker end. I still use it all the time and have some great waterfall shots with it, but on bright days I have to limit the exposure to about 15s to avoid killing all the blue in the shot.

I've been searching to buy a air filter for my kia sedona and luckily I found it. I used Wix brand of air filter but it was disposable and don't last for long. K&N cost a little but it will last for long.
