Bisher habe ich als leicht ambitionierter Hobbyfotograf noch keinen Polarisationsfilter verwendet, somit handelt es sich hier um meinen ersten Kontakt mit deartigem Fotoequipment. Verarbeitungstechnisch habe ich nicht allzu viel erwartet, wurde aber positiv überrascht. Der metallische Filter wirkt insgesamt sehr wertig und sauber verarbeitet. Ich verwende eine Canon EOS 550D, auf dessen Standardobjektiv sich der Filter problemlos aufschrauben lässt. Um den Filter entsprechd justieren zu können, muss man den Filter natürlich entsprechend festziehen, sodass er sich nicht direkt wieder löst. Gegebenenfalls ist es dann allerdings auch etwas knifflig den Filter wieder zu entfernen. Der leichte Widerstand beim Drehen ermöglicht präzises und punktgenaues Einstellen.Die gewünschten Effekte erbringt der Filter problemlos. Gerade beim Entfernen ungewünschter Reflektionen arbeitet der Filter effektiv. Der Bildeindruck scheint mir insgesamt etwas weicher zu sein als ohne Filter und der Lichtverlust ist nur minimal. Meines Erachtens intensiviert sich der Farbeindruck nur sehr geringfügig, eher wirken die Bilder durch leichte Kontrasterhöhung und subtile Verdunklung edler. Beim Fotografieren von Himmeln wird das Blau aus meiner Sicht nicht bedeutend verstärkt, dafür erhalten Wolken aber eine schönere Struktur. Alles in allem also eine gute und preisgünstige Ergänzung zum Fotoequipment, mit deren Hilfe man seine Fotografien subtil verbessern und modifizieren kann.

Just received my new keurig but one part is missing it’s the dial for the months on the filter

Hat man eine Osmo Pocket sind die Filter einfach ein muss.Kaufempfehlung.

Good replacement filter, you really notice and it helps the engine rev a lot more freely.

filter fits perfect but doesn't feel like any additional horsepower and definitely no mpg gain at all, that being said, the savings will come bc we replace these filters 2 times a year so after one year we will see a dollar amount savings just by keeping this filter cleaned.

Perfect fit for replacement paper filter. First thing I replace on all my cars.

Before I get started with the review, a note on packaging: These filters each come in a very large cylindrical case that's quite different from what I'm used to my filters arriving in. That's not a criticism, merely something I thought I'd mention because I was struck by it when these were first delivered. There's nothing wrong with these cases per se, but I am in the dark as to what benefit they're supposed to offer over the usual design.Anyway. I should explain where I'm coming from in order for this review to make sense. The majority of pro mist filter reviews I've seen suggest sticking with the1/8 strength because the reviewer finds the 1/4 produces too pronounced an effect. With all due respect, I want my filters to produce a pronounced effect. I don't keep filters (other than the UV) on my lens unless I specifically want to change the picture in a particular way. At such times the change should be noticeable! If it's too much I'll just take the filter off and shoot without it. I sometimes compare a lens filter to a jacket: I want my jacket to be heavy because, if I wear it outside and find that I'm too warm, I can simply take it off; but if I wear it outside and find I'm too cold, now what am I supposed to do?In a perfect world I think I probably would have skipped the 1/8, 1/4, and 1/2 filters and gone straight to a 1. But beggars can't be choosers, so I've got the 1/8 and 1/4 combo pack.You can see my test shots, which are of a perfectly ordinary naked light bulb in an otherwise dark room. It was a small room so I underexposed all of the pictures by two full stops in an attempt to duplicate outdoor conditions where the light would not have reflected off the surfaces of such a tight space. I used one of those cork screw shaped light bulbs rather than an old-fashioned one that's shaped like an actual bulb (hmm) so that there would be a bit more contrast baked into the image. Focal length and all other variables were controlled for across all shots, including my position relative to the bulb. Apologies that I wasn't able to keep all four images perfectly centered, seeing the bulb slide around as I move from one picture to the next annoys my OCD quite a lot. But setting up my tripod seemed like more trouble than it was worth, and since the background is dark, it doesn't make a difference for test purposes.The first shot is the control: No filter at all. Contrast is quite high. The second shot is the 1/8 filter. The effect is very subtle but not negligible. The third shot is the 1/4. The effect here is pronounced: the white balance is warmer and the halation is fairly dramatic. The fourth shot was an experiment in stacking both filters to see if that would yield even more pronounced results. Somewhat to my surprise, the effect is actually less pronounced than using the 1/4 alone, though more pronounced than the 1/8. (By the way, the threads on them are solid but not very smooth, and produce an unpleasant nails-on-a-chalkboard type screech as I screw them together. I stacked and unstacked them quite a few times just to try the threads out, and on one occasion I needed to use filter wrenches to separate them.)Based on my experiments it seems that the 1/4 filter is where it's at. By contrast, I don't think I'll give the 1/8 filter one of the coveted spots in my very crowded filter pouch. At one point I actually considered doing the hairspray trick on one of these filters to see if I could make the pictures even mistier (especially if I was going to stack the filters, as I could spray the filter at the bottom of the stack and seal the sticky surface between the two). Then I thought, if an improvised trick like that, which is meant to be used on a $6 UV filter, is necessary to get a $90 pro mist filter to look like a pro mist filter, then what's the point? Thankfully, based on my test shots, I don't think that will be necessary.EDIT: It looks like when this review posted, Amazon changed the order of the test shots for no reason. So the first shot is no filter, the second shot is the stack, the third is 1/8 and the fourth is 1/4.

K&N will always be better than a stock filter. I did notice a little better pickup and mileage but not a huge difference. I put the filter in my 08 silverado 4.3l v6. I would imagine that a CAI would give you more horsepower but I didnt want to spend the money on that.
