What is the disadvantage of extension tubes?

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.

Do extension tubes increase magnification?

An extension tube increases lens magnification by an amount equal to the extension distance divided by the lens focal length. For example, adding a 25 mm extension tube to a 50 mm lens will give a magnification gain of 0.5X.

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.

Can I use extension tubes with a zoom lens?

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.

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.
