To ellis49: Shallow DOFgerhardt::2005-11-18 2:28
Hi Gert,

I am not sure if I took this photo with or wothout the 1.4TC. I did not keep notes. :)

What would the impact of the TC be on the DOF given the fact that the distance to the subject and all other settings remain the same?

Extension tubes woulld narrow the DOF and give less light, right?

What would happen with extension tubes and TC ? In what order do you place them on the camera? TC first then tubes then lens?

Would you gain any benefit from this setup? Theoretical the TC gives you added working distance and the tubes less?

Kind regards
Gerhard
