This is a continuation of a report on new ways to look at depth of field. The series starts here: A new way to look at depth of field I will have more to say about the hyper-hyperfocal distance that I talked about yesterday, but I want to get started on something that I promised… [Read More]

This is a continuation of a report on new ways to look at depth of field. The series starts here: A new way to look at depth of field We’ve seen in this series that stopping down giveth depth of field (DOF), and taketh away sharpness (measured in terms of MTF50, Is there a way… [Read More]

This is a continuation of a report on new ways to look at depth of field. The series starts here: A new way to look at depth of field   Yesterday, we looked at the focus distance that made a minimal impact on the sharpness for objects at infinity, with minimal being defined as a… [Read More]

This is a continuation of a report on new ways to look at depth of field. The series starts here: A new way to look at depth of field On DPR, someone asked an excellent question: We frequently talk about focusing at infinity, or at some large distance, but it often seems, to me at… [Read More]

This is a continuation of a report on new ways to look at depth of field. The series starts here: A new way to look at depth of field A reasonable, if somewhat relaxed, portrait distance for a 55mm lens is 2 meters. I have done some actual DOF testing with the 60mm f/4 Coastal… [Read More]
