Macro tubes increase the lens-to-sensor distance, allowing for closer focusing than what is normally allowed by the lens itself. The greater the length of the extension tube, the closer the lens can focus.

By placing distance between your camera body and lens, focusing distance is shortened and the magnifying effect of your subject is created. Macro tubes increase the lens-to-sensor distance, allowing for closer focusing than what is normally allowed by the lens itself. The greater the length of the extension tube, the closer the lens can focus. This means you can now get macro performance without needing to switch to a specialized lens and you will retain all the normal benefits of your optic when the macro function is not in use.\u003c\/p\u003e\n\u003cp\u003eThe camera mount coupling adapter and lens mount coupling adapter can be used independently of the extension tubes or you can add in the tubes for extreme macro photography. Because no other optical components are added with this kit, the image preserves the original optical properties of the lens. This is an affordable and simple way to turn your existing lens into an inexpensive macro lens. This tube set includes a lens-coupling ring and a body-coupling ring; three extension tubes of various sizes are also included to build up to the desired magnification.

By placing distance between your camera body and lens, focusing distance is shortened and the magnifying effect of your subject is created. Macro tubes increase the lens-to-sensor distance, allowing for closer focusing than what is normally allowed by the lens itself. The greater the length of the extension tube, the closer the lens can focus. This means you can now get macro performance without needing to switch to a specialized lens and you will retain all the normal benefits of your optic when the macro function is not in use.\u003c\/p\u003e\n\u003cp\u003eThe camera mount coupling adapter and lens mount coupling adapter can be used independently of the extension tubes or you can add in the tubes for extreme macro photography. Because no other optical components are added with this kit, the image preserves the original optical properties of the lens. This is an affordable and simple way to turn your existing lens into an inexpensive macro lens. This tube set includes a lens-coupling ring and a body-coupling ring; three extension tubes of various sizes are also included to build up to the desired magnification. Life size image can be achieved with this set up.\u003c\/p\u003e\n\u003cp align=\"right\"\u003e\u003cspan style=\"text-decoration: underline; color: #0000ff;\"\u003e\u003ca href=\"#top\"\u003eBack to Highlights\u003c\/a\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003e\u003cspan style=\"text-decoration: underline; color: #0000ff;\"\u003e\u003ca href=\"https:\/\/www.cambridgeincolour.com\/tutorials\/macro-extension-tubes-closeup.htm\" target=\"_blank\"\u003eExtension Tubes Overview ¹\u003c\/a\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003eAn extension tube is simply a hollow cylinder that fits in between your camera and lens, causing the lens to move farther from the sensor.

By placing distance between your camera body and lens, focusing distance is shortened and the magnifying effect of your subject is created. Macro tubes increase the lens-to-sensor distance, allowing for closer focusing than what is normally allowed by the lens itself. The greater the length of the extension tube, the closer the lens can focus. This means you can now get macro performance without needing to switch to a specialized lens and you will retain all the normal benefits of your optic when the macro function is not in use.\u003c\/p\u003e\n\u003cp\u003eThe camera mount coupling adapter and lens mount coupling adapter can be used independently of the extension tubes or you can add in the tubes for extreme macro photography. Because no other optical components are added with this kit, the image preserves the original optical properties of the lens. This is an affordable and simple way to turn your existing lens into an inexpensive macro lens. This tube set includes a lens-coupling ring and a body-coupling ring; three extension tubes of various sizes are also included to build up to the desired magnification. Life size image can be achieved with this set up.\u003c\/p\u003e\n\u003cp align=\"right\"\u003e\u003cspan style=\"text-decoration: underline; color: #0000ff;\"\u003e\u003ca href=\"#top\"\u003eBack to Highlights\u003c\/a\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003e\u003cspan style=\"text-decoration: underline; color: #0000ff;\"\u003e\u003ca href=\"https:\/\/www.cambridgeincolour.com\/tutorials\/macro-extension-tubes-closeup.htm\" target=\"_blank\"\u003eExtension Tubes Overview ¹\u003c\/a\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003eAn extension tube is simply a hollow cylinder that fits in between your camera and lens, causing the lens to move farther from the sensor.

By placing distance between your camera body and lens, focusing distance is shortened and the magnifying effect of your subject is created. Macro tubes increase the lens-to-sensor distance, allowing for closer focusing than what is normally allowed by the lens itself. The greater the length of the extension tube, the closer the lens can focus. This means you can now get macro performance without needing to switch to a specialized lens and you will retain all the normal benefits of your optic when the macro function is not in use.\u003c\/p\u003e\n\u003cp\u003eThe camera mount coupling adapter and lens mount coupling adapter can be used independently of the extension tubes or you can add in the tubes for extreme macro photography. Because no other optical components are added with this kit, the image preserves the original optical properties of the lens. This is an affordable and simple way to turn your existing lens into an inexpensive macro lens. This tube set includes a lens-coupling ring and a body-coupling ring; three extension tubes of various sizes are also included to build up to the desired magnification. Life size image can be achieved with this set up.\u003c\/p\u003e\n\u003cp align=\"right\"\u003e\u003cspan style=\"text-decoration: underline; color: #0000ff;\"\u003e\u003ca href=\"#top\"\u003eBack to Highlights\u003c\/a\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003e\u003cspan style=\"text-decoration: underline; color: #0000ff;\"\u003e\u003ca href=\"https:\/\/www.cambridgeincolour.com\/tutorials\/macro-extension-tubes-closeup.htm\" target=\"_blank\"\u003eExtension Tubes Overview ¹\u003c\/a\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003eAn extension tube is simply a hollow cylinder that fits in between your camera and lens, causing the lens to move farther from the sensor.

By placing distance between your camera body and lens, focusing distance is shortened and the magnifying effect of your subject is created. Macro tubes increase the lens-to-sensor distance, allowing for closer focusing than what is normally allowed by the lens itself. The greater the length of the extension tube, the closer the lens can focus. This means you can now get macro performance without needing to switch to a specialized lens and you will retain all the normal benefits of your optic when the macro function is not in use.\u003c\/p\u003e\n\u003cp\u003eThe camera mount coupling adapter and lens mount coupling adapter can be used independently of the extension tubes or you can add in the tubes for extreme macro photography. Because no other optical components are added with this kit, the image preserves the original optical properties of the lens. This is an affordable and simple way to turn your existing lens into an inexpensive macro lens. This tube set includes a lens-coupling ring and a body-coupling ring; three extension tubes of various sizes are also included to build up to the desired magnification. Life size image can be achieved with this set up.\u003c\/p\u003e\n\u003cp align=\"right\"\u003e\u003cspan style=\"text-decoration: underline; color: #0000ff;\"\u003e\u003ca href=\"#top\"\u003eBack to Highlights\u003c\/a\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003e\u003cspan style=\"text-decoration: underline; color: #0000ff;\"\u003e\u003ca href=\"https:\/\/www.cambridgeincolour.com\/tutorials\/macro-extension-tubes-closeup.htm\" target=\"_blank\"\u003eExtension Tubes Overview ¹\u003c\/a\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003eAn extension tube is simply a hollow cylinder that fits in between your camera and lens, causing the lens to move farther from the sensor.

By placing distance between your camera body and lens, focusing distance is shortened and the magnifying effect of your subject is created. Macro tubes increase the lens-to-sensor distance, allowing for closer focusing than what is normally allowed by the lens itself. The greater the length of the extension tube, the closer the lens can focus. This means you can now get macro performance without needing to switch to a specialized lens and you will retain all the normal benefits of your optic when the macro function is not in use.\u003c\/p\u003e\n\u003cp\u003eThe camera mount coupling adapter and lens mount coupling adapter can be used independently of the extension tubes or you can add in the tubes for extreme macro photography. Because no other optical components are added with this kit, the image preserves the original optical properties of the lens. This is an affordable and simple way to turn your existing lens into an inexpensive macro lens. This tube set includes a lens-coupling ring and a body-coupling ring; three extension tubes of various sizes are also included to build up to the desired magnification. Life size image can be achieved with this set up.\u003c\/p\u003e\n\u003cp align=\"right\"\u003e\u003cspan style=\"text-decoration: underline; color: #0000ff;\"\u003e\u003ca href=\"#top\"\u003eBack to Highlights\u003c\/a\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003e\u003cspan style=\"text-decoration: underline; color: #0000ff;\"\u003e\u003ca href=\"https:\/\/www.cambridgeincolour.com\/tutorials\/macro-extension-tubes-closeup.htm\" target=\"_blank\"\u003eExtension Tubes Overview ¹\u003c\/a\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003eAn extension tube is simply a hollow cylinder that fits in between your camera and lens, causing the lens to move farther from the sensor.

By placing distance between your camera body and lens, focusing distance is shortened and the magnifying effect of your subject is created. Macro tubes increase the lens-to-sensor distance, allowing for closer focusing than what is normally allowed by the lens itself. The greater the length of the extension tube, the closer the lens can focus. This means you can now get macro performance without needing to switch to a specialized lens and you will retain all the normal benefits of your optic when the macro function is not in use.\u003c\/p\u003e\n\u003cp\u003eThe camera mount coupling adapter and lens mount coupling adapter can be used independently of the extension tubes or you can add in the tubes for extreme macro photography. Because no other optical components are added with this kit, the image preserves the original optical properties of the lens. This is an affordable and simple way to turn your existing lens into an inexpensive macro lens. This tube set includes a lens-coupling ring and a body-coupling ring; three extension tubes of various sizes are also included to build up to the desired magnification. Life size image can be achieved with this set up.\u003c\/p\u003e\n\u003cp align=\"right\"\u003e\u003cspan style=\"text-decoration: underline; color: #0000ff;\"\u003e\u003ca href=\"#top\"\u003eBack to Highlights\u003c\/a\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003e\u003cspan style=\"text-decoration: underline; color: #0000ff;\"\u003e\u003ca href=\"https:\/\/www.cambridgeincolour.com\/tutorials\/macro-extension-tubes-closeup.htm\" target=\"_blank\"\u003eExtension Tubes Overview ¹\u003c\/a\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003eAn extension tube is simply a hollow cylinder that fits in between your camera and lens, causing the lens to move farther from the sensor.

Macro extension tubes are a wonderful alternative to expensive macro lenses. Macro extension tubes maintain the original optical quality while transforming the normal lens into a macro lens. By placing distance between your camera body and lens, focusing distance is shortened and the effect of magnifying your subject is created. Because no optical components are added into this extension tube, the image preserves the original optical properties of the lens.\u003c\/p\u003e\n\u003cp\u003eThis is far more desired than the close-up lenses which are added to the front of the lens via filter thread, which alter the optical quality resulting in a blurry image full of artifacts. Adding an extension tube increases the effective aperture, reducing the amount of light entering the camera, which means you will need to use either a longer shutter speed or higher ISO to compensate for the loss of light. Your camera, if it's set to an automatic exposure mode, will take care of this automatically for you.

Macro extension tubes are a wonderful alternative to expensive macro lenses. Macro extension tubes maintain the original optical quality while transforming the normal lens into a macro lens. By placing distance between your camera body and lens, focusing distance is shortened and the effect of magnifying your subject is created. Because no optical components are added into this extension tube, the image preserves the original optical properties of the lens.\u003c\/p\u003e\n\u003cp\u003eThis is far more desired than the close-up lenses which are added to the front of the lens via filter thread, which alter the optical quality resulting in a blurry image full of artifacts. Adding an extension tube increases the effective aperture, reducing the amount of light entering the camera, which means you will need to use either a longer shutter speed or higher ISO to compensate for the loss of light. Your camera, if it's set to an automatic exposure mode, will take care of this automatically for you.

Macro extension tubes are a wonderful alternative to expensive macro lenses. Macro extension tubes maintain the original optical quality while transforming the normal lens into a macro lens. By placing distance between your camera body and lens, focusing distance is shortened and the effect of magnifying your subject is created. Because no optical components are added into this extension tube, the image preserves the original optical properties of the lens.\u003c\/p\u003e\n\u003cp\u003eThis is far more desired than the close-up lenses which are added to the front of the lens via filter thread, which alter the optical quality resulting in a blurry image full of artifacts. Adding an extension tube increases the effective aperture, reducing the amount of light entering the camera, which means you will need to use either a longer shutter speed or higher ISO to compensate for the loss of light. Your camera, if it's set to an automatic exposure mode, will take care of this automatically for you.

Macro extension tubes are a wonderful alternative to expensive macro lenses. Macro extension tubes maintain the original optical quality while transforming the normal lens into a macro lens. By placing distance between your camera body and lens, focusing distance is shortened and the effect of magnifying your subject is created. Because no optical components are added into this extension tube, the image preserves the original optical properties of the lens.\u003c\/p\u003e\n\u003cp\u003eThis is far more desired than the close-up lenses which are added to the front of the lens via filter thread, which alter the optical quality resulting in a blurry image full of artifacts. Adding an extension tube increases the effective aperture, reducing the amount of light entering the camera, which means you will need to use either a longer shutter speed or higher ISO to compensate for the loss of light. Your camera, if it's set to an automatic exposure mode, will take care of this automatically for you. Macro extension tubes are an affordable and simple way to turn any existing lens into a macro lens.\u003c\/p\u003e\n\u003cp align=\"right\"\u003e\u003cspan style=\"text-decoration: underline; color: #0000ff;\"\u003e\u003ca href=\"#top\"\u003eBack to Highlights\u003c\/a\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003e\u003cspan style=\"text-decoration: underline; color: #0000ff;\"\u003e\u003ca href=\"https:\/\/www.cambridgeincolour.com\/tutorials\/macro-extension-tubes-closeup.htm\" target=\"_blank\"\u003eExtension Tubes Overview ¹\u003c\/a\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003eAn extension tube is simply a hollow cylinder that fits in between your camera and lens, causing the lens to move farther from the sensor.

Macro extension tubes are a wonderful alternative to expensive macro lenses. Macro extension tubes maintain the original optical quality while transforming the normal lens into a macro lens. By placing distance between your camera body and lens, focusing distance is shortened and the effect of magnifying your subject is created. Because no optical components are added into this extension tube, the image preserves the original optical properties of the lens.\u003c\/p\u003e\n\u003cp\u003eThis is far more desired than the close-up lenses which are added to the front of the lens via filter thread, which alter the optical quality resulting in a blurry image full of artifacts. Adding an extension tube increases the effective aperture, reducing the amount of light entering the camera, which means you will need to use either a longer shutter speed or higher ISO to compensate for the loss of light. Your camera, if it's set to an automatic exposure mode, will take care of this automatically for you.

Macro extension tubes are a wonderful alternative to expensive macro lenses. Macro extension tubes maintain the original optical quality while transforming the normal lens into a macro lens. By placing distance between your camera body and lens, focusing distance is shortened and the effect of magnifying your subject is created. Because no optical components are added into this extension tube, the image preserves the original optical properties of the lens.\u003c\/p\u003e\n\u003cp\u003eThis is far more desired than the close-up lenses which are added to the front of the lens via filter thread, which alter the optical quality resulting in a blurry image full of artifacts. Adding an extension tube increases the effective aperture, reducing the amount of light entering the camera, which means you will need to use either a longer shutter speed or higher ISO to compensate for the loss of light. Your camera, if it's set to an automatic exposure mode, will take care of this automatically for you.
