K&F CONCEPT 67mm-82mm Metal Step Up Ring

Correctly made with smooth threads that do not bind. A great solution for saving money on rarely used filters like expensive polarizers.

they do the job, unsure why they give you two of them but they're great, they do what you want them to do and seem good quality, very light.

This item is a set of two step-up rings. I now know the dimensions, and the terminology (step-up / step-down) work from the camera outwards, i.e. towards the subject. They arrived in a sealed package, with the description clearly shown, so I could check it was the correct item before opening. Each of the two rings was packaged separately in a clear plastic bag, and their dimensions are clearly marked in white text against the black anodised surface. I will NOT mix these up easily. There is also a vacuum packed microfibre cloth. The whole set is in a larger plastic storage box, which is very robust. The threads on the rings, both internal and external, have been manufactured to acceptable tolerances, and fit my filters and lens with reassuring precision. The after sales support is exemplary, with replies in less than one working day, from a named individual.

Great value. Durable, work as expected. They don't get stuck.

Impressive for the price. The 49mm - 55 mm fit my ancient Pentacon 1.8/50 exactly and easily screwed on There are two stepping rings, a microfibre cleaning cloth and a plastic case in the pack. Both rings are sturdy, thin and professionally finished. The case is big enough for more than two rings separated with tissue paper and the size marking on the ring allows for easy identification.

I have a number of products from K&F, and they have all been really good quality which is why I had no hesitation about purchasing this step up ring. It is good quality and a simple yet perfect solution to extend the use of the brilliant K&F Concept Pro square filter system on other 58mm lenses. The step up ring (2 supplied, in plastic case with soft microfibre cloth) attaches seamlessly between the lens and the 67mm adapter ring of the filter holder. Very thin construction so there is minimal extra bulk when combined to the overall set up. This is a good inexpensive solution allowing me to use my filter system on more lens combinations, as currently there is no 58mm filter system adapter ring available. Very happy with the purchase and would definitely recommend this K&F product and the K&F brand as a whole.

Amazing quality and I was very impressed will be looking into more of these products

Fits as expected, lightweight, easy screw on, good adaptor to have

Ho utilizzato questi anelli **step-up da 55 mm a 77 mm** per poter montare i miei filtri da 77 mm su un obiettivo con filettatura da 55 mm, e si sono rivelati molto utili. L’adattatore si avvita semplicemente sulla filettatura frontale dell’obiettivo (55 mm) e consente di utilizzare filtri più grandi come **UV, CPL o ND da 77 mm** senza problemi. La costruzione in **lega di alluminio anodizzato** è leggera ma abbastanza robusta, e le filettature sono precise: l’anello entra facilmente e i filtri si avvitano senza impuntamenti. Questo tipo di adattatore è ideale per **standardizzare i filtri su un diametro più grande**, evitando di acquistare lo stesso filtro in più misure. ([Walmart.com][1]) Nella confezione sono inclusi **due anelli**, utile se si hanno più obiettivi o come ricambio, oltre a un **panno in microfibra** per la pulizia delle lenti. Pro: costruzione in metallo leggera e resistente filettature precise e facili da montare permette di usare filtri da 77 mm su obiettivi da 55 mm confezione con due anelli + panno di pulizia Contro: con alcuni obiettivi il paraluce originale potrebbe non essere più utilizzabile Nel complesso è un accessorio economico ma molto pratico per chi usa filtri fotografici e vuole ridurre il numero di diametri diversi nel proprio kit.

Cumplen perfectamente, son geniales. Muy económicos comparados con la competencia, muy bien presentados en sus estuches rígidos estoy muy contento con la compra.

Helt ok, funkar.

اشتريته لتركيب فلاتر 82 على عدسات 52

Très bonne qualité, tient bien en place sans rester bloqué. Je recommande !
