These spacers are ideal to get that back focus accurate - a good range of sizes
product is well made and threads have been formed well within tolerances (nice secure fit without binding)
the 'blacking' is a little bit shiny to start with this should dull down with being outside (no reflection perceived)
Ideal when changing the cameras to suit target
excellent service by FLO as always
