What is the disadvantage of extension tubes?

The only disadvantage of extension tubes is that there is some light loss. Adding an extension tube increases the effective aperture of the camera lens, which means you need to use either a longer shutter speed or higher ISO to compensate for the loss of light.

Can you use extension tubes with zoom lenses?

It is recommended to use extension tubes on standard-length lenses; however, they will work on any focal-length lens, including wide-angle and zoom lenses.

Do extension tubes reduce image quality?

An extension tube, regardless of brand, does not degrade image quality since it has no lens. As the name suggests, it is just a tube with no glass in it.

How do you focus on extension tubes?

The best way to use extension tubes is to set the lens to manual focus. You can use the manual focusing ring on your lens to focus on the subject. Depth-of-field is very narrow this close up. Don't be afraid to raise your ISO in order to get a small enough aperture to give you adequate depth-of-field.

What is a macro extension tube used for?

Lens extension tubes extend the magnification of your lenses. They provide an inexpensive and effective starting point in building a macro photography kit. These tubes fit between the camera body and the lens. They twist onto your camera as a normal lens would, and then the lens attaches to their front.

How do macro tubes work?

What they are is exactly what their name implies – little tubes that extend the lens. Essentially what it does is shifts the focus zone of the lens; you will no longer be able to focus at infinity but it will allow you to get closer so you can do those macro shots.

What is extension tube for Canon?

The Canon EF 25mm Extension Tube II is used to allow a lens to focus closer than it does natively. This is accomplished by moving the lens 25mm farther away from the camera body's sensor/film plane by fitting between the camera body and the lens.

What do extension tubes do in photography?

An extension tube is a hollow, light-tight tube that fits between your lens and your camera mount. It moves your lens further from the camera, and the front element closer to the subject. The closer you can focus, the more magnification you get. The above photo shows a 50mm lens fitted with a 25mm extension tube.
