Extension Tubes for Canon EOS DSLR

This set includes three extension tubes measuring 10mm, 16mm and 21mm for Canon EOS DSLR cameras. They allow standard lenses to focus closer for macro photography. The tubes contain no optical elements and preserve the original lens quality. Auto-focus is maintained at f/5.6 or brighter apertures.

Practical Limits of Extension Tubes

Extension tubes reduce the minimum focusing distance but also decrease the amount of light reaching the sensor. Longer tube combinations require brighter lighting or slower shutter speeds. Auto-focus performance depends on the lens maximum aperture staying at f/5.6 or wider. Infinity focus is lost when any tube is attached.

Magnification Control Through Tube Length

The combined length of the tubes used determines the maximum magnification achievable. Stacking the 10mm, 16mm and 21mm tubes provides the closest focusing distance. Buyers who need variable magnification without changing lenses will find this flexible. Photographers requiring infinity focus while shooting macro should consider alternative close-up solutions.

Questions about this item

Should I use the 10mm, 16mm or 21mm tube for the magnification I want?

Each tube increases magnification by moving the lens farther from the sensor; the 21mm tube gives the closest focus and highest magnification, the 10mm the least, and they can be stacked for intermediate steps.

Will autofocus still work with these tubes on my lens?

Autofocus is maintained at f/5.6 or brighter; at smaller apertures the camera may hunt or fail to lock focus.

Do the tubes keep electronic communication with a Canon EOS body?

Yes, the set preserves the electronic contacts so aperture control and EXIF data pass through to the camera.
