How to Choose Adapter Ring?

• First of all you have to buy the appropriate physical lens adapter required to get your lens attached to your camera. For this you should consult your favourite camera shop . But a number of manufacturers build simple metal ring adapters that let you attach various types of lenses
• If you've got, for example, a lens designed for an old Pentax threaded (screw mount) camera like the Pentax Spotmatic you'll need an adapter for M42 lenses. Same with the new line of Carl Zeiss ZS lenses, which also use M42. If you have a telescope you'll probably need a T-mount adapter, assuming your telescope has the ability to be hooked up to a camera at all. Or if you have a Nikon lens you'll need an adapter that lets you fit Nikon F lenses to your EOS body. Likewise Leica R, Leica Visoflex, Olympus OM, Contax/Yashica RTS, Rollei, and Contax manual focus, or even big Hasselblad, Mamiya 645, Pentacon 66, Pentax 645 and Pentax 6x7 medium format lenses can all be adapted. Microscopes apparently often require C-mount adapters. Tamron built a series of Adaptall II lenses and you can still occasionally find used Adaptall II->EOS adapters around. I have links to some sources for these adapters at the end of the page
• Most adapters are simply metal rings with an EF bayonet on one side; And since the EF mounting ring is larger in diameter than most 35mm SLR lens mounts quite a few lenses can be adapted to the EOS system

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
