Diopter distance?


Recommended Posts

Is there a rule to measure what diopter to use on certain distances?

For example a 100mm taking lens on a FF. with a 2X anamorphic lens with a diopter of +1= focus is everything in 1 meter

+2 everything between 1 and 2 meters? 

Or something like that? As I would like to know what diopters are good to have in my bag.

 

Thanks!

+0.5 diopter = 2000mm max focus distance when lens set to infinity and minimum focus distance half the original

+1 diopter = 1000mm max focus distance when lens set to infinity and minimum focus distance quarter the original

+2 diopter = 500mm max focus distance when lens set to infinity and minimum focus distance one eighth of the original

+4diopter = 250mm max focus distance when lens set to infinity and minimum focus distance one sixteenth of the original
