Extension tube

Extension tubes
A set of three different sized hollow tubes that fit in any combination between the lens and camera body to extend the lens-to-film distance and increase its close focus capability.

EXTENSION TUBES OVERVIEW
An extension tube is simply a hollow cylinder that fits in between your camera and lens, causing the lens to move further from the sensor.

Extension Tubes
An Extension Tube is a tool used in macro photography that attaches to the face of the camera at one end and to the lens at the other end.

Techniques Glossary Extension tube
A hollow tube that fits between the lens and camera body to extend the lens-to-film/sensor distance and increases its close-focus capability.

Do extension tubes effect image quality?
Extension tubes do not effect image quality due to the fact that it is not optically changing your camera lens.

Macro extension tubes are camera accessories intended to move the lens farther from the image plane and are used mainly in macro photography.

Extension Tubes
An extension tube is merely a hollow ring that can be mounted between a lens and camera to provide greater extension.

EXTENSION TUBES
Another way to make the Nikonos focus closer than the standard 0.8 metre is to move the 35 mm lens away from the film by fitting an extension tube between the lens and the camera body.

Extension Tubes
If the lens you are using will not focus close enough there are a couple of ways to make it do so. If the lens is detachable from the camera, you can use 'extension tubes'.

Extension tube: The extension tube has no glass inside, but does move the lens farther from the sensor plane, thereby shifting the focus range.

Extension Tube
Extension tubes increase magnification by fitting between the lens and camera body (SLR/DSLR) and are used for macro and closeup photography.

EXTENSION TUBES - Tubes made from metal and, more frequently, plastic inserted between the lens and the camera, thereby making the lens to film distance greater. The result is increased magnification for close-up photography.

Extension tubes. Metal rings attached between the camera lens and the body to allow closer-than-normal focusing in order to increase the image size.

Extension Tubes: Hollow metal tubes that mount between the camera and the lens to permit closer that normal focusing. The longer the extension the closer the lens will focus, a lower priced substitute for a bellows unit.

Extension tubes.
Metal tubes used to obtain the additional separation between lens and film for close-up photography. They are fitted with screw thread or bayonet mounts to suit various lens mounts.

Extension tubes
Metal tubes added to 35mm or medium format cameras, to extend the lens film distance, enabling a magnification greater than x 1(life size).

Extension tubes. Rings or short tubes mounted between camera body and lens to space the lens further away from the film and so allow the sharp focusing of very close subjects.

Extension tubes: These look like and attach to the camera the same way as teleconverters do, except they have no glass built into them. Extension tubes are used mainly for close-up photography and can be used with any lens.

Extension tubes
I don't recommend using these, I think it is better to use a diopter or teleconverter. The extension tubes will make your port needs much longer, and you have to deal with loss of light.

Extension Tube
This is a lens enclosure without any glass elements. You attach an extension tube to your camera and then the lens to the end of the tube. This device allows you to be nearer the subject and remain in focus.

Extension tubes ramp up the magnification even more. They attach to the end of your macro lens, and they come in all kinds of shapes and sizes.

Extension Tubes
These are metal tubes of varying lengths that are attached between the camera body and the camera lens. There is a basic principle they exploit to achieve higher magnifications using normal camera lenses.

Extension tubes allow you to get even closer by increasing the distance between the camera and the film surface or sensor, although focusing does become more of a challenge.

Extension tubes fit between a removable lens and the camera body and allow the lens to focus much closer than normal, giving increased magnification. The larger the amount of extension, the greater the increase in magnification.

Extension tubes can be used with any lens, but the screw in closeup lenses will only fit lenses of a certain filter size.

Extension tubes will allow you to focus closer to your subject and therefore increase image magnification. The main drawback to this method is loss of working distance from your subject.

An extension tube fits between the lens and the camera body. An extension tube is essentially a hollow tube that contains no lens elements. An extension tube moves the lens farther from the sensor; this allows the lens to focus closer.

Adding extension tubes causes significant loss of light of up to two stops but your TTL metering system will compensate for this. However, I would recommend taking some test shots with your extension-lens-flash combo before going on a bigger shoot.

If you have extension tubes or a macro lens you can use them as an alternative to the close-up lens.

You can add extension tubes or bellows between your lens and camera body. I always focus manually so these extensions being manual focus only is no bother.
Close up lenses don't help that much at life size.

3) Buy an extension tube.
These are hollow plastic tubes which fit between the lens and the camera body, thereby increasing the distance of the lens to the camera and thus reducing the close focus distance of your lens.

2 Get some extension tubes. Extension tubes are simply empty tubes (no optics) that fit between your lens and camera body. They can be used with any lens to make it focus closer and at high quality.

If you don’t want to lay out the big bucks for a macro lens, you can use extension tubes, a bellows, or close up filters. Of the three, I opt for the filters for their ease of use.

The underwater photo examples originally were made using the Nikonos underwater system-a body and flash with two lenses (a 15mm wide-angle and 35mm with extension tubes for close-up work).

Unlike a macro lens, there's no glass in an extension tube. It's a hollow cylinder designed to sit between a DSLR and a non-macro lens, presumably whatever you typically shoot with (like a telephoto or wide angle lens).

True macro photography requires a close-up dioptre lens, macro lens, and/or extension tubes. You can use several of these in combination with each other and your camera's regular lens to achieve very close-up and macro photography.

If you have a little more to spend, you could consider investing in an extension tube.

Extension Ring Also known as Extension Tubes. An Extension Ring is a device placed between the lens and camera body to extend the lens-to-film (or imaging sensor) distance for closer focusing. Find out more.

HUMMINGBIRD TIP: Arm yourself with a 500mm (or equivalent) telephoto and 50mm worth of close-up extension tubes. Shoot under bright overcast skies. Build a better background by repositioning a feeder near flowers or by setting up your own bouquet.

A multiplier for the exposure increase required when the light reaching the film is decreased from either increasing the distance between the lens and the film (as with extension tubes and bellows) or when a filter is attached.
