    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

    Adapter ring compatibility problems and infinity focus

    • The most common problem is that of lens registration - the distance from the lens mount to the film plane. It may not be possible to build a lens adapter that gets this distance right for certain lens mount systems
    • For example, the back focus distance (distance from the rearmost lens element to the film plane) on EOS cameras is 44mm, but on Leica rangefinder cameras it's 27.8mm. Matching the back focus distance would require a lens mounted deep inside the camera body; not usually an option. In cases such as this you may either have to buy an adapter ring that won't let you achieve infinity focus or you'll have to get an adapter ring which contains one or more glass lens elements and which will inevitably degrade the image quality somewhat. These compensating elements let you achieve focus to infinity, though at the expense of image quality. Contax G, Konica F, Leica M, Minolta MD and Miranda lenses are other lens mounts with back focus distances less than that of Canon EOS
    • There is also the case of lenses which have lens register distances very close to that of a true Canon EF lens. Contax/Yashica lenses (45.5mm) and Canon EF lenses (44mm), for example, have only a 1.5mm difference in lens registration, and 1.5 is awfully thin for a metal ring adapter. Such adapters have to be machined to incredibly close tolerances in order for infinity focus to work, which means they can be quite expensive. Cheaper ones often have to be sanded down to maintain infinity focus - but even that is something of a dodgy proposition as you have to sand the surface down accurately from one side to the other, down to a fraction of a millimetre
    • Also appears that it isn't possible to make adapter rings that let you mount Pentax K (bayonet mount) lenses on EOS cameras with EF lens mounts. The Pentax K diaphragm coupling lever physically interferes with such a possibility. So you'd have to modify the lens (or the camera) to make such a conversion possible. Note that this does not apply to cameras compatible with the EF-S mount. The design of the EF-S mount, with its smaller mirror box thanks to the 1.6x crop factor, coincidentally permits the use of such lens adapters
    • Finally, and this isn't strictly to do with manual focus lenses per se, but you can't use Minolta Vectis or Four Thirds (Olympus, Kodak, Fuji, Sanyo, Sigma, Panasonic and Leica) lenses on EOS cameras. These lenses, in addition to being autofocus lenses, cast very small image circles; much too small to cover the imaging area of EOS cameras. In theory I suppose the Vectis lens design might cover an EF-S sensor, but it would probably be pointlessly expensive to make such an adapter

    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

Fair purchase for the price
03:21:33 11-02-2012
Not bad thing for such a price. Metal, not plastic. Easy to install and remove

The black coating is rather tender. Cannot support AF lenses, but what do you want for less then $10.

Well, this thing may be very useful if you have some manual lenses which you want to experiment with. But as I have already bought macro lens I'm not sure I shall use it often

Great value! Limited use

That is not a problem with this product, just an attribute of using extension tubes that you should know about if you haven't used them before.

Does exactly what it is supposed to do
00:00:00 05-16-2011
You will not be able to use these with autofocus but it really shouldn't matter because the depth of field is razor thin and you will need to manually focus anyway to get your desired shot. All they do is block light and extend the lens out from the body in order to achieve the magnification at the reduced distance. Pretty simple. They seem to have decent enough quality to last.

Useful tool
00:00:00 05-13-2011
I read few reviews about this product and then ordered it. I have used it with my camera with 18-55mm and 55-250mm lens. Considering the price it is an excellent bargain. You cannot use autofocus and aperture control. Aperture is manageable once you set its value, use DOF button and detach lens at the same time. It leaves the aperture there. I took pictures of icicles from window, in daylight, handheld across the window glass. It gave me marvelous results. I high recommend this product for those who want to save money and can play around with things manually.

My Review
00:00:00 05-09-2011
This is yet, another impeccable piece of perfection created by Canon. The order came in days before I expected it and it is at a great price compared to the other extension tubes. I have been having so much fun with my piece for extreme close-ups that my friends even say I am addicted to using it. A great buy!

Camera Extension Tube
00:00:00 05-05-2011
This was an easy purchase. I was looking for a way to take close up pictures of small items. This item was well described and pictured. I knew it would fit my camera and lens as it was stated in the description. It was shipped quickly and was well packaged. I was very satisfied with the purchase and would recommend it to anyone looking for such an EOS accessory.

This extension tube set was an excellent and in-expensive alternative to a Macro lens. I also very much appreciated Fotodiox's prompt responses to my e-mailed inquires.
