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 If you’re coming late to this party, here’s some background on object field methods. It is a tenet of the object-field (OF) approach to depth of… [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, I modeled a really great lens, the Zeiss Otus 85/1.4 ZF.2, and ran a set of depth of field curves. Today, I’ll do the same… [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 One of the things that I’ve been meaning to get to is better modeling of the on-axis performance of a really good lens. I’ve taken as… [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 When I first started my investigations into depth of field management, I was driven by two very separate things that ganged up to point me in… [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 object field MTF50 behavior with the lens focused at infinity, and found that with our simulated top drawer 55mm lens, a simulated… [Read More]
