Use of Converters as a DOF Tool

greenspun.com : LUSENET : Pentax 67 SLR : One Thread

Has anyone used the 1.4x or 2x converter as a means to increase the DOF at a certain focal length? For example, if I want an f/45 90mm, I could attach the 2x to a 45mm. Anyone tried this combination? I would love to have a 150mm with f/45 DOF. Was wondering how feasible this is using the 75mm and 2x? I considered the 1.4x but it is quite limited in the lenses it can use. SR
