Macro magic - a guide to close-up camera kit    
Words and pictures by Peter Bargh (article updated Jan 2012)

Close up photography can be expensive if you buy a true macro lens. But there are less expensive ways of going in close.

Each of the close-up gadgets used for this article were attached to the camera and, to ensure consistency, the lens was set to infinity in each shot. It is possible, in some cases, to get a larger magnification by focusing at a closer setting. The camera was tripod mounted and the distance from the subject to the front of the lens was measured to give a useful reference for photographers shooting timid insects. The results are shown as full 35mm frames so you can compare the size of image from each product as it would appear.

Macro Lens

All dedicated close up photographers either own or lust after a pukka macro lens as they have the advantage of offering a near perfect performance and gains the close-up ability by just rotating the lens barrel. With most of the other options you have to attach the accessory to do close ups and remove it to go back to distant photography. All fiddly stuff! The Micro Nikkor lens used for this shot, like most true macro lenses, is designed to work at its optimum for close-ups. It delivers a 1:2 half life-size ratio - or 1:1 with optional PK-13 tube, some manufacturers provide lenses with true 1:1 ratio without requiring an optional converter.

Many of the less expensive products featured here go in much closer, offering greater subject magnification, but few do it as well as a macro lens which produces razor sharp images.

Reversing Ring

A reversing ring, as the name implies, reverses the lens on the camera body. You need to buy one that matches your body mount with the lens' filter thread. All auto coupling is lost so program exposure and shutter-priority modes are not possible, but most cameras will work okay in aperture-priority or manual mode using stop down metering. 

A reversing ring offers a life-size image that's razor sharp in the centre, but a little softer at the edges compared with a macro lens, but the price is excellent.

Extension Tubes

These are a set of three tubes in different lengths that go between the camera and lens to offer a choice of macro ranges.

They are available in a variety of lengths ­ 12mm, 20mm, 25mm and 36mm, and are sold singly or in sets of three that can be used in any combination to give six options. Their only real drawback is that there is a loss of light in the tubes - this adjustment is made automatically by modern cameras with through-the-lens metering, but compensation is required if you're using non TTL flash. Used in conjunction with a 50mm lens, a 25mm tube gives you half-life-size image, and a full set 1:1 reproduction. We added all three tubes to show the larger than life-size reproduction. As there are no elements inside the tubes, quality is as good as the original lens and the size and versatility is perfect for the nature photographer.

Close-Up Lens

This is a small dioptre lens that's often wrongly referred to as a filter. It's available from most filter manufacturers including a version for Cokin's A and P square filter system. They're available in three magnifications: +1, +2 and +3 and, like tubes, can be used in any combination to vary the magnification. Using all three together gives a combined +6 magnification which is on the edge of macro world, but individually they're quite limited for this sort of photographer. They're ideal for larger subjects such as flowers or for anyone wanting to copy old photographs though. The metering and exposure modes in your camera aren't affected so close up lenses are simple to use, and if you use the Cokin version the one filter will adapt to a wide variety of lenses with the relevant filter ring. The quality of results is on a par with those from the reversing ring.

Close-up lenses set +1, +2, +4

Close-up lenses individually don't always offer enough magnification, but add them together and it's a different story. We screwed together a +1, +2, +4 to give a +7 magnification.

You can expect a loss in quality because light will bounce off all the lens to air surfaces. This appears as slight overall softness with a reduction in contrast. Even so, the quality is still acceptable for most of us and, unless you're intending making big enlargements, it's a good option to consider.

+10 macro lens

This option is the extreme of the close-up lens, offering a powerful +10 magnification. It's simple to use and gives no loss of light or problems with camera metering using auto exposure modes. The image, however, appears no sharper than the combined close-up lenses, so if your subjects vary in size go for the more versatile close up lens set.

Macro Converter

This seven-element 2x converter has the added benefit of a macro mode which extends out to offer a 1:1 life-size ratio. You lose two stops of light, but the metering coupling is maintained so your camera will take care of the exposure, even in auto mode. The converter, made by Teleplus, is available in most manual focus lens mounts including Canon, Nikon, Olympus, Pentax, Minolta and Yashica and is a very versatile option. The results produced are the closest you'll obtain to having a true macro lens. Use it with a telephoto lens and you have a powerful magnifier from close up and afar.

Bellows

Bellows are the most flexible and versatile of all the ultra close up accessories, but they're also the most bulky, cumbersome and fiddly to use. They consist of a rack that attaches to the tripod with a set of rubber or cloth bellows mounted on front and back frames. The frames have a lens mount on one end and a camera mount on the other. To increase magnification you extend the bellows. This will either adjust by unlocking the rail and manually sliding it to the necessary extension or by a rack and pinion method. The latter is the more precise type. Both usually have a fine focus control to ensure the sharpest results.

When the bellows are extended you really need a TTL meter or you will have to manually compensate for the loss of light reaching the film. The further you extend the lens from the film the more light lost.

Some of the more expensive models have an additional focus rail that lets you swiftly move the whole camera/bellows position closer to the subject so you don't have to continually adjust the tripod position.

Coupling Ring

This adaptor requires two lenses to function - one is attached, as normal, on the camera, the other is reversed on front of the camera lens. The ring screws into the filter thread of both lenses. This method offers the closest focus of them all, but care is needed when choosing lens and aperture combinations. The best results are obtained when a smaller focal length lens such as a 50mm is reversed on the front of a longer one, say 105mm. You need to shoot with the reversed lens at the maximum aperture because the image goes black at the edges as you stop down. Results are sharp at the centre, but there's considerable fall off in quality towards the edges of the photo.
