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..
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.
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.
Do extension tubes affect sharpness?
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).
Can you use extension tubes with any lens?
You can use extension tubes with any type of lenses: primes or zooms, portraits, or even macro! Extension tubes are an inexpensive way to get the kind of short focusing distances that you get from a dedicated and much more expensive macro lens.
Can I use the zoom lens as a macro lens?
If you don’t have a dedicated macro lens to photograph insects and flowers with, then the next best alternative is a zoom lens macro. There are many advantages to using a zoom lens for macros and closeups including: there is no need to be close to the subject.
What focal length is best for macro?
All things considered, macro lenses with a focal length of between 90mm and 105mm are most popular. They’re a manageable size and weight, affordable to buy, and have a convenient minimum focus distance of around 30cm.

Does extension tube change focal length? Adding an extension tube (or tubes) to the lens effectively changes the focal length. Because the aperture is calculated with focal length as a variable, the lens’s f-numbers change, as well. Therefore, your lens’s maximum aperture f-number is no longer the same when tubes are added—it is smaller.
Do extension tubes degrade the quality of the image?
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.
Is a 50mm lens good for macro?
Macro magnification and other lens options
It can actually be done with any lens but a 50mm will give you a 1:1 or true macro scale image. Long lenses will not give you as much magnification and wide angle lenses will give you more (28mm is about 3:1).
Do extension tubes change depth of field?
Extension tubes do affect the depth of field off a lens. However, this is more noticeable when you are close to the subject rather than when taking shots close to the maximum focusing distance of the telephoto lens. To increase the depth of field and have more of the subject in focus, move further away.
Do extension tubes change aperture?
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.
What is a macro extension?
Can you use a close-up lens with a macro lens? Like extension tubes, these filters allow you to achieve closer focus for close-up photographs using your “regular” lenses—no special dedicated macro lenses need to be used. And, yes, you can also use these filters to boost magnification on macro lenses, too!
Are macro filters any good? Filters are small and easy to transport and, if used with telephoto lenses, will provide far more magnification than extension tubes. But most importantly, macro filters don’t affect exposure or viewfinder brightness and your autofocus will still work as normal. This is not to say that macro filters are perfect.
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.
Can extension tubes damage your camera?
I’d be surprised if even defective extension tubes could “destroy” a camera, though I guess anything is possible. Non-destructive but annoying errors however do seem possible. In other words, the camera failing to work properly when the tubes are attached is one thing; the camera needing repair as a result is another.
How do you remove extension tubes from lenses?
1. Push the release pin towards the camera and hold it in as you rotate the lens to remove it from the extension tube assembly. 2. Press the lens release button on the camera and rotate the exten- sion tube assembly to release it from the camera, just as you would remove a normal SLR lens.
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.
Does Nikon make extension tubes?
Nikon produces a range of auto extension tubes which can be used with Nikon Ai, Ai-s, AF, AF-D and AF-S (D-type) lenses. Nikon auto extension tubes do not have CPU contacts required to adjust the aperture electronically using the camera dials.
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 difference between extension tubes and teleconverters?
an extension tube pushes the lens element closer to the subject. Teleconverters can focus to infinity, an extension tube reduces the maximum focal distance.
Is a teleconverter the same as extension tube? Quick contrast. Teleconverters act as a magnifying glass vs. an extension tube pushes the lens element closer to the subject. Teleconverters can focus to infinity, an extension tube reduces the maximum focal distance.
Can you stack macro filters?
Stack to Increase Magnification
You can stack close-up filters on top of each other to increase your magnification. All you have to do is screw on a close-up filter onto the filter that is already on the lens.
