• hood is in good condition and used for most RB lenses

This hood can be attached by screwing it into the lens ring.  When using it as the hood for the 127mm, 180mm, and 250mm lenses, pull the folded rubber hood straight out.  For the 90mm lens, fold it back half way.

When using a filter with this hood, please screw the filter into the lens first and then attach the hood onto the filter.
