If you use 2 different lenses, say a 50MM and a 100 MM .....which gives more wide depth of field? The subject area that is in the VF is the same using either lens, implying that the camera will move closer to the subject with the 50 than the 100.... The taking aperture is the same. The only difference is the distance to the subject ( the 50MM is closer )..... Please quote DOF distances in MM or inches....Please do not get into the circle of confusion, etc. Hold all those variables constant... The purpose in this question is to figure out if a wider angle lens has the same or wider DOF: if it does, then the closer proximity to the subject ( Half the distance) using the wider lens will alow a 2 stop smaller F-stop using a flash, therefore increasing DOF even more....a big bonus to tne macro types.... Thanks for helping.... I am trying to figure out which R series Macro lens I should explore...
