What does a 25mm extension tube do?

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. The end result of focusing closer is a larger magnification.

What is the difference between an extension tube and an extender?

Extension tubes (with no glass) will not reduce quality but just get you closer. The tele-extenders will reduce quality a bit (for 1.4x) or more (for 2x) but will crop tighter from farther back and make it easier to shoot without shading or scaring the subjects.

Do extension tubes increase working distance?

The extension tube serves to increase the distance between the lens and the sensor. This allows the lens to focus closer and, therefore, increase magnification, so you can use almost any lens for close-up photography. As with a macro lens, the longer the focal length, the greater the working distance you can achieve.

Do extension tubes reduce image quality?

In addition, because the extension tube does cause your lens to focus more closely than it was designed to, this can cause decreased sharpness and image quality (not because it changes the optics but because it changes how you are using your lens).

Do extension tubes change magnification?

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 the disadvantage of extension tubes?

Do extension tubes work with zoom lenses?

Extension tubes can be used with long telephoto zoom lenses. This type of set-up tends to give photographers more latitude when photographing subjects that are a few feet away from them, for example bees or butterflies that are a few feet inside a bed of flowers rather than on the periphery.
