What is Adapter Rings?
- Adapter Rings allow the adaption of "Series Sized Filters" to your lens. Adapter rings contain two components: an adapter ring and a retaining ring. A Series Sized filter is a glass filter that does not contain filter threads. The Series Filter is held in place between the Adapter ring and the Retaining Ring
- The advantage of this method is utilizing same sized filter on a number of different sized lenses by attaching different sized lens adapters
- Not all lenses are designed with standard filter accessory screw in thread sizes. For these lenses, many of which are very popular, the way to mount a filter is via an adapter ring. A main feature of adapter rings is that you can utilize one size filter with a number of different sized lenses via different adapter rings
- An Adapter ring consists of two parts: an adapter ring and a retaining ring. The non-threaded filter is held in place between the two as you screw the retaining ring into the adapter ring. The adapter ring is than screwed directly into the lens or is mounted to the outside diameter of the lens barrel via a setscrew lock ring adapter
- To stack non-threaded filters, a second retaining ring is required to be threaded into the first retaining ring and the second filter is than held in place between the two
- Adapter rings contain two measuring specifications: 1) the direct screw in size to the lens such as 86mm, 95Cmm, etc / or outside lens diameter to mount a setscrew lock ring and 2) the size of the filter that the adapter wil1 accommodate
- Example: 105Cmm-4-1/2'' screws directly into a lens requiring a 105Cmm accessory size and accepts 4-1/2"round size non-threaded filters
- Example: 124SSLR-138mm features an adapter that set screws over a lens barrel (SSLR) with an outside diameter of 124mm and accepts 138mm round non-threaded filters
- Larger or smaller filters than the designated filter size may also be utilized on lenses via a Step Up or
- Step Down ring. To determine which type ring you need, start with the lens accessory size of your lens and convert it to the desired filter size needed to be used
- Example: A lens featuring a 62mm accessory size with the need to mount a 77mm filter would require a 62mm-77mm Step Up ring
- Example: A lens requiring a 58mm accessory size with the need to mount a 52mm filter would require a 58mm-52mm Step Down ring. It is not suggested to utilize a Step Down ring more than a two-size difference between the lens and filter otherwise lens vignetting may result
How to Use Camera Lens Adapter Rings:
- Purchase a close up lense if you are photographing things like plants, insects, jewelry and maybe even food items. Close up lenses, which screw into the front of the camera lens, contain multiple elements of optical glass and are used to change the focus range of the lens. They come in different magnifications and are sometimes sold in sets. A 1X adapter will halve the focus range of your lens. If your lens could focus at 3 feet, you can now focus at 1.5 feet. With a 2X adapter you could focus .75 feet. They dramatically reduce the depth of field, as is true with all macro photography. They are also usually the least expensive accessory lenses to purchase
- Telephoto Adapter: Buy telephoto adapters if you need to extend the telephoto range of the lens. These also contain multiple optical glass elements and are attached to the rear of the lens and then directly onto the camera. They are more expensive than close lenses and are very camera specific since they need to couple with the camera's autofocus and exposure mechanisms. You need to also be conscious of the weight it will add to the lens. A 2X adapter will turn a 200mm lens into a 400mm lens. It can also be used with zoom telephoto lenses. These adapters are great for sports and wildlife photography and are also used in street photography
- Bellows: Purchase an adapter that will alter the perspective of your camera in the same way a view camera does if you are doing architectural and scenic photography or any assignment where the perspective is critical. You can purchase an adapter like the one pictured at the top of this article from LensBaby (see Resources below). These adapters screw into the front of the lens and allow you to tilt the front element to alter the perspective and eliminate converging lines. Another way is to purchase a bellows like the one pictured here. This option actually provides more control since you have a bellows extension and front element tilt both available. You can always adjust perspective in post production, but you will lose some of the image in the editing process
- Fisheye Adapter: Buy special effects lens adapters like the fisheye adapter (pictured here) if you need to turn your wide-angle lens into a fisheye lens. You can also find polarizing filters to minimize reflections from water and glass. Both of these adapters are useful in general photography and provide a function that cannot be achieved in post production. There are also multiple image adapters, clear spot adapters, soft focus adapters and many more. These are much less useful in the digital age since all of the special effects can be easily created in post production
