Re: Focus Errors and Sensor Size ...
In reply to Detail Man, Aug 29, 2013

I find Falk Lumo's interesting Section 2.3 (Defocus) quite interesting (as well as complicating):

... with a much better formatted PDF version of the same text and graphics found here:

I consider the dramatic (square or cubic) improvement of focus accuracy with sensor size to be the main advantage of a larger sensor size as it can't be offset by use of equivalent lenses.

- Section 2.3.5 (A Note on Equivalency)

Methinks that the above statement (alone) would be an excellent subject to further explore. If it is true, then there exists a specific (and not commonly mentioned) advantage of larger Sensor Sizes.

My little GH2 and LX3 are already sniffling and weeping at the proposition they may not be "perfect".
