K&F CONCEPT CPL Filter for iPhone, 52mm Polarizing for iPhone Lens

Filming videos through the windscreen of a car you usually end up with quite distracting reflections, especially driving along a tree lined road with sun flicker. This lens filter removed 90% of windscreen reflections and in parts of my footage it looks like there is no windscreen at all! Now, I've read the one star reviews saying it doesn't work, but that's because the user doesn't know how polarising filters work. They have to be rotated to give the desired polarisation. If rotated to the "wrong" position the glare increases, but if rotated to the right position, the glare all but disappears - and that's why the lens is rotatable! But the effect is difficult to see with today's monitor screens, even on a large screen cellphone. So it requires some sacrificial shots that you can view on a large monitor. In my application with the clip upright, the lens was rotated such that the two grooves were horizontal, and that cancelled out 90 percent of reflections. Perhaps try that before misleading would-be purchasers with one star "do not buy" reviews, which are very misleading and annoying.

I think this had been returned by a previous buyer. The box was not wrapped in cellophane as one of their previous filter had been, and the opening edge was crumpled. The filter itself is packed in a plastic box with a foam fitting, the inside of the lid has a lot of scratches, making it look as though the filter had been taken in and out several times, although at present I cannot see any damage to the filter and the clip is strong. It fits my iPhone 16 Pro in a case, but I have not yet been able to test it completely, so far I have only achieved the result I expected once, and yes, I do know how they work having frequently used fiiters on a DSLR.

Game changer for better quality pictures with your phone! Massive difference when used.

Didn't make the slightest difference to any of my photographs. Clunky to get on and off. Useless product.

I bought this to photograph my oil paintings. I always struggled to photograph them without the glare. However, this lens is amazing. It erased the glare even on dark colours.

Average could be better but could be worse

Works quite well and does fit on a large range of phones. Got some great shots with this.

Walked by coventry river on a half gray to white clouded day. The purpose was to test the lens when viewing water which glows from sunlight. Water can look fizzy and it did reduce it to be fair. It was a small reduction in glow but, enough to make the visuals more decent. Glow can be annoying on surfaces and can lose detail in visuals until it is tinted like cars, glass windows, rivers, limestone, tarmac.

[Edit]: Nach einer 3-Sterne-Bewertung wurde ich vom Vertrieb angeschrieben, die meine Unzufriedenheit bedauerten und boten Ersatzprodukte an. Fand ich super. Diese gab es aber dann nicht in meiner Wunschgröße, so dass ich am Ende eine Gutschrift erhalten habe. Top-Service! Danke! Der Filter macht grundsätzlich, was er soll – allerdings nur in bestimmten Situationen. Spiegelungen lassen sich tatsächlich nur bei getöntem Glas zuverlässig reduzieren. Bei klarem Glas, z. B. Fensterscheiben oder Plexiglas ohne Tönung, bringt der Polarisationsfilter wenig bis gar nichts. Hier bleiben die Spiegelungen einfach bestehen, besonders wenn hellere Umgebungen reflektiert werden. Gebäudefotografie ohne Spiegelung ist also keine erfolgreiche Mission mit dem Produkt. Ich habe den Filter bisher hauptsächlich an Glasflächen getestet. Flüssigkeitsoberflächen (z. B. Wasser) konnte ich noch nicht ausprobieren – das werde ich noch nachholen und meine Bewertung ggf. ergänzen. Wichtig für Interessierte: Wer denkt, dass sich mit diesem Filter alle Spiegelungen auf jeder Glas- oder Flüssigkeitsoberfläche komplett entfernen lassen, wird enttäuscht werden. Der Effekt ist begrenzt und hängt stark von der jeweiligen Situation ab. Fazit: Solides Zubehör, aber mit klaren Grenzen. Für bestimmte Anwendungen praktisch, für "Wundereffekte" ungeeignet. Preis-Leistung je nach Anwendungsfall ok.

Produit conforme qui fait bien son travail. Le filtre fonctionne parfaitement. Rien à redire.

Très bien si vous faite du carspotting la calité est vraiment bien et pour les moto

ما أنصح فيه، تأثيره قليل جداً لدرجة أنه يستاهل

Works great, son uses it for his detailing videos. Happy with the purchase.
