Yes the 72 mm is the filter size - 28mm-200mm with 72mm filter size- they were discontinued being replaced by 62mm- I am hoping this will help with more light and clearer images - a suggested setting I found was F11 - 1/160- 400 film speed.
This is an auto/manual lens and I have ordered an adapter that has a "chip" in it to be programed so my Canon T3i will work with it. If not I like to shoot manual as that is how I stated with my SLR.

You indicate several times that this is a 72mn lens. I believe that this is the FILTER size, not the focal length.
