EXTENSION TUBES MACRO AF FOR CANON EOS

Specification:

• gold-plated contacts instead of aluminum (better conduction and longer durability)
• they do not degrade image quality (they do not have any optical elements)
• solid bayonets
• they can be combined freely
• made only from the best components
• allow the use of multiple lenses
• allow all body functions to be used
• cause a decrease in the lens brightness calculated by the formula: Fr = F (f + d) / f [where: Fr - actual lens brightness; F- aperture set on the lens; f - focal length; lens (in mm); d - length of rings]
