Likvid,if you calculate the focal length all in inches then isn't the resulting f/d ratio also in inches? Eg an f/d ratio of .42 should mean(as a decimal) just under half an inch(where .5 would be half inch)does that make sense? |
F/D is just a constant explaining the Focal length To Diameter Of the Dish Ratio, does not have anything to do with length in inches or mm.
