Depth of field tables

Tables showing depth of field and hyperfocal distances for various combinations of focal length and aperture. With apologies to our American friends, all distances are in metric units.

For APS-C DSLRs

These tables are for APS-C digital SLRs like the Canon EOS 350D. They use a circle of confusion of 0.016mm, which is on the conservative side for APS-C, so you may find you get a little more depth of field than is indicated.

For fixed-lens 35mm rangefinders

These tables are for the fixed-lens rangefinder cameras that were made by various Japanese companies in the '60s and '70s. There are tables for focal lengths of 40, 42 and 45mm over a couple of different aperture ranges. Between them they cover all the popular Canon Canonet and Olympus models of the 1970s, and probably a number of other cameras as well. They assume a circle of confusion of 0.030mm which is a pretty typical value.
