    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. 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 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

    • 1 x MASSA Camera Lens Filters Step Down 30mm-25mm Adapter

Screw threads work well. Item is solid construction.

None that I have found so far.

Recommend this item for anyone wanting a good quality step down filter ring. Price is also very good.

Works as advertised
00:00:00 10-01-2009
What can I say, it works as advertised, a good adapter ring with solid structure. It allows the use of 25mm filters and accessories on a lens with a 30mm filter thread. I have useed it for nearly half a year. No problem found yet. Yet the price is reasonable. So I can say it was a good purchase, highly recommend this item to all of you.
