The affect of F stop on DOF with a 100mm macro
I am trying to understand the EF100mm non USM macro lens, so I have been shooting at 1:1, the closest focal point and closing the apperture down to see the change in DOF these were all shot at iso 400 f/2.8 the pin has a curve across the top and a line on the bottom of the frame which are in focus. As the f/ stop icreases,… -

The larger apertures don't give enough DOF (unless your going for the very limited DOF look) and the smaller apertures, while… -

I have seen some nice photos that exploited an extream limited DOF to good advantage. Unfortunately, this is not one of them:): . f/3.5 1/60 ISO 800 This one turned out a…
