Useful and easy – Digital DoF Review

Was concerned about the only bad review that says it is not accurate. So compared it to Cambridge in Colour online calculator and got good agreement with CoC set to 0.011 mm for generic 35 mm sensor (with Cambridge calculator set to 20/20 vision). So you should set it for your preferred CoC value, in sensor distances rather than enlarged print distances.
