Hello Wim,

How do you come to this numbers 1,5 and 1 2/3 stops?

According to my cacluations.



1,5 crop must have 2,25 times higher DOF - in terms of stops it is 1,17 Stops

1,6 crop must have 2,56 times higher DOF - 1,35 Stops.



With Kind Regards,

Miro



PS Finally I fond Wim to say something wrong. :-)
