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..
Are extension tubes worth it?
And then again, if you are just an occasional macro photographer, or if you don’t have the money to spend on a macro lens, extension tubes are a very good choice. These tubes are small, lightweight, and can be used with almost every lens, even a macro lens.
Can I use extension tubes with a zoom lens?
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.
What is a Canon extension tube?
An extension tube is an accessory that increases the magnification of a lens simply by moving the optics further away from the camera.
Can you stack Canon extension tubes?
How do you use Extension Tubes? You attach extension tubes between your camera body and the lens. You can use one or stack them for maximum effect.
How many stops do you lose with a 2X teleconverter?
A 1.4X teleconverter loses one stop. A 2X teleconverter loses two stops. You can stack some teleconverters, but it is usually a desperation measure–news photographers, for instance. Two 2X teleconverters will lose 4 stops of light.
How do you calculate extension tube magnification?
The extra magnification is calculated by dividing your extension tube length by the focal length of your camera lens. It is important to note that this is additional magnification. Each lens has a defined magnification at its Minimum Focusing Distance.
Can you shoot macro with telephoto lens?
That’s when I put on a longer lens and turn to telephoto macros. I used the Olympus 40-150mm f/2.8 PRO to capture these flowers. I zoomed in to 105mm (210mm equivalent) and was several feet away from the subject.
Lenses.

What is a macro lens Canon? A macro lens is a lens that specifically allows you to focus extremely close to a subject so that it appears large in the viewfinder (and in the final image).
What is the disadvantage of extension tubes?
Extension Tube Disadvantages
Provides only a minimal magnification gain with telephoto lenses. Causes your lens to lose the ability to focus on distant objects. (as described in the tutorial on macro lenses: effective f-stop). Causes your lens to focus more closely than it was designed.
Can you use extension tubes for portraits?
The further away your lens is from the sensor, the closer your lens can focus. For macro photography, you’ll need close focusing. Lens extension tubes extend the magnification of your lenses. They provide an inexpensive and effective starting point in building a macro photography kit.
Do extension tubes reduce light?
Because extension tubes do not have optics, they do not affect the optical quality of a lens. Because of their function, there are other effects: decrease of light; shallower depth of field; and loss of ability to focus at infinity. The longer the extension tube, the closer the lens can focus.
How many extension tubes can I use?
How do you use Extension Tubes? You attach extension tubes between your camera body and the lens. You can use one or stack them for maximum effect.
What lens is best for extension tubes?
Extension tubes are most effective when used with lenses of focal lengths between 24-100mm. They are not so effective when used with telephoto lenses (for these, use a close-up lens). You can’t use an extension tube with some wide-angle lenses as it becomes impossible to focus with it fitted.
What is the disadvantage of using a macro filter? What is a disadvantage of using a macro filter? They can degrade the quality of the image. Insects are best photographed at midday when the insects are more active.
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.
Which is better close-up filters vs extension tubes?
Extension tubes are more expensive, but also a more versatile option. They show the best results with wide angle lenses, but strongly lose out to close-up filters on telephoto lenses. Rings do not have optics, and therefore do not bring distortion into the image.
How are extension tubes calculated?
Extension Tube Formulas
- The (minimum) magnification with lens focus set to Infinity is. Magnification = Exten_length / Focal_length.
- The (maximum) Magnification at Closest Focus is. Magnification =
- The additional internal focus extension at Closest Focus is. internal extension = Focal_length x Closest_Mag.
Can I use an extension tube with a 35mm lens?
Extension tubes and magnification
Extension tubes work best with lenses of focal lengths between 24 and 100mm. They are not so effective when used with telephoto lenses (a close-up lens is the best option). You can’t use an extension tube with some wide-angle lenses as it becomes impossible to focus with it fitted.
What does a Canon extension tube do?
An extension tube is an accessory that increases the magnification of a lens simply by moving the optics further away from the camera.
Do extension tubes increase magnification?
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 change aperture?
What is a lens extender used for?
Lens extenders (also known as teleconverters) increase the effective focal length of your lenses. Find out how lens extenders can enhance your telephoto capabilities and prove helpful especially when you can’t physically get closer to your subject.
What does a lens doubler do? A teleconverter allows you to increase the apparent focal length of a lens, giving you a greater telephoto effect than a lens alone. A teleconverter is basically a magnifying lens that is placed between the camera body and lens.
