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]

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 Some people think of blur in terms of CoC, others (like myself) in terms of MTF50. Is there a way to bridge the divide? Indeed there… [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 looked yesterday at the distance sharpness implications for focusing at the hyperfocal distance with the standard 30 micrometer (um) circle of confusion (CoC), and they… [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 No doubt you’re familiar with the depth of field (DOF) markings on your lenses. If you’ve got manual focus lenses, the markings are probably fairly detailed…. [Read More]

This is the first of what turned out to be a very deep dive into depth of field. To see all the other posts in the series, scroll down to the bottom of this page — below the comments — and you’ll find links to all the other posts. I haven’t posted for a few… [Read More]
