Macro Extension Tube set for SLR cameras with M42
lens mount is composed of 3 extension tubes - 7mm, 14mm, and 28mm with M42х1 screw
mount adapters. Mount the tubes between lens and camera body to get your choice
of macro ranges - 8 combinations in total, made from anodized aluminum.
Mounting Extension Tube in between the camera body and lens will create
more distance between the lens and film plane. By moving the lens further away
from the film or digital camera sensor, the lens is forced to focus much closer
than normal. The greater the length of the extension tube, the closer the lens
can focus.
Use this set with your normal lens and you will get the quality, which
is as good as the original lens and the size, sharpness and versatility is
perfect for the macro and close-up pictures.
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.
This Extension tube can be also used with the modern Digital SLR cameras
with M42 lens and M42 adapter for your camera body.
