There are few things we, as photographers, are more OCD about than tack-sharp focus. We invest so many of our hard-earned dollars into nice glass, painstakingly focus, then spend hours in post afterwards pulling our hair out when the eyes aren’t sharp. While of course sometimes OOF images are due to user error, small variations in the lens and camera can result in less-than-sharp images. These discrepancies in camera / lens combination can be dialed in to get perfectly sharp images more consistently. Enter FoCal, a [semi]automated focus calibration software.
