Introduction<\/h2>\n

H&Y Revorings<\/figcaption><\/figure>\n

H&Y has been responsible for some innovative filter solutions for cameras over the last years (e.g. the magnetic filter holders<\/a>) but there is still something I am sure most of us filter users are not happy with: adapter rings. This is a problem the so called “RevoRing” is meant to solve, so let us have a look how it works.<\/p>\n

<\/p>\n

How does it work?<\/h2>\n

A RevoRing can be described as a mix of an adapter ring and an aperture diaphragm. It allows to attach one (bigger) size of filter to several lenses with different (smaller) filter threads.<\/p>\n

The RevoRing comes in different sizes that accomodate different ranges of lens filter threads. At the time of writing this article the following sizes are available:<\/p>\n\n\n\n\n\t\n\t\n\t\n\t\n\t\n\t
Filter Size<\/td>Filter Thread (Lens)<\/td>\n<\/tr>\n
52mm<\/td>37-49mm<\/td>\n<\/tr>\n
67mm<\/td>46-62mm<\/td>\n<\/tr>\n
77mm<\/td>52-72mm<\/td>\n<\/tr>\n
82mm<\/td>67-82mm<\/td>\n<\/tr>\n
95mm<\/td>82-95mm<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n

The RevoRings are also available with already built-in neutral density + polarizer filter.<\/p>\n

Handling<\/h2>\n

The diaphragm in the RevoRing is spring loaded, so before attaching it to a lens you need to hold the lower ring with one hand and rotate the upper ring with your other hand. You can then put it on your lens, release the spring and the RevoRing will be attached to your lens. I made a short video showing how it works:<\/p>\n
