Micnova KK-C68P AF Macro Extension Tube Set for Canon (12mm/20mm/36mm) 60D 70D 5D2 5D3 7D 6D 650D 600D 550D

Extension tubes are designed to enable a lens to focus closer than its normal set minimum focusing distance. Getting closer has the effect of magnifying your subject (making it appear larger in the viewfinder and in your pictures). They are exceptionally useful for macro photography, enabling you to convert almost any lens into a macro lens at a fraction of the cost while maintaining its original optical quality.

This Autofocus Extension Tube Set (12/20/36mm) for Canon from Micnova contains three tubes of different length, a 12mm, 20mm, and 36mm, which can be used individually or in any combination to obtain the desired magnification.

Features:
For close-up photography.
3 tubes to vary magnification.
Be used for Canon EF & EF-S SLR cameras.
Designed with all the circuitry and mechanical coupling, these extension tubes are able to maintain autofocus and TTL auto exposure normally.
Can be used individually or in combination.
With plastic construction and lens mount index.
Front and rear caps prevent the dust into the tubes.
The greater the length of the extension tube, the closer the lens can focus.

Note:
Do not look at the sun or a bright light source through the lens with an extension tube mounted, or through the camera with a lens that has an extension tube mounted. Doing so could result in loss of vision. Looking at the sun directly through the lens with an extension tube mounted is especially hazardous.
Do not leave a lens with an extension tube mounted or a camera with a lens that has an extension tube mounted under sunlight without the lens cap attached. This is to prevent the lens from magnifying the sun's rays, which could cause fire.
