How do you calculate extension tube 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.
What lenses go with 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.
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.

What does a telescope extension tube do?

What is the best option for taking a macro photographs?
Macro photography should be done in color, not in black and white as this hides detail. Landscapes are the one type of photograph where you should always use the traditional perspective. A photograph of a plain or prairie can also be turned into something quite interesting with active skies.
Can you use close up filters with macro lens?
Close up filters work as a secondary lens which attaches to your main camera lens and allows closer focusing of your subject (think macro photography)! With the use of close up filters, you can do just that – get closer to your subject and decrease the minimum focal distance.
