NOW YOU CAN USE YOUR FILTERS ON ALL YOUR LENSES EVEN IF THEY ARE MISMATCHED.An age old problem for photographers is having to buy a filter for every lensthey own. Typically a photography kit has a collection of wide, medium andtelephoto lenses. The construction of each lens is somewhat dictated by itsfunction. The result is they all have different front diameters. Each lens has athreaded section up front for screwing on a filter or accessory. These two partshave to be matched by their diameter. If your lens has a front diameter of 82mmyou need to buy an 82mm sized filter. If your second lens is 77mm you are forcedto buy a second filter. Quality filters can be pricy and add up when they needto be duplicated for every combination you own.What is an adapter ringStep up rings or step down rings, also known as adapter rings, allow you to usefilters and accessories even if they are not the same size as the thread on yourcameras lens. Lenses and filters come in a large range of types and sizes andunfortunately they don't always fit together interchangeably. Within this widerange of possible sizes there is at least a level of standardization.Fortunately, there is a step up or step down filter for just about any need.How step up rings workStep up rings provide a way to fit a larger diameter filter or accessory onto asmaller lens. Every adapter is a metal ring with a male and a female thread. Themale thread screws onto the lens, the female thread accepts the accessory. Inthe case of a step up ring, the male thread is a smaller size and screws ontoyour lenses threading. The opposite side has the larger diameter female thread,to which you can then attach the filter or accessories or even more step uprings to match diameters 2 or more steps larger.How step down rings workStep down rings work in the exact same way but instead provide a way to attachsmaller accessories and filters to larger lenses. So their male thread attachesto the front of the lens, and on the opposite side of the ring in a narrowerdiameter female thread.It is important to note that typically, the farther away from the lens you placea filter the worse the optics will be. It is always best to look for thethinnest adapter ring that you can find as these will keep the filter close tothe lens. Stacking adapter rings or using step down rings may lead to vignettingas they become visible withing the cameras field of view.PLEASE NOTE K&F have full spares support in South Africa when purchased throughan authorised dealer.
