Manual Extension Tubes are designed to enable a lens to focus closer than its normal minimum focusing distance. They have the effect of magnifying your subject and are useful for macro photography, allowing you to convert almost any lens into a macro lens while maintaining its original optical quality. All functions are in manual mode using these extension tubes--7mm, 14mm, and 28mm--which can be used individually or in any combination to obtain the desired magnification.
With all M42 mount lenses you will need to use manual focus and manual aperture while shooting. Please make sure that your M42 lens has a switch or button to put the lens into stop-down mode, commonly referred to as the Auto-Manual or A/M switch.
