    That should always be the case right? The OMD has a DOF of a 17.5mm lens even if it has an EFL of 35mm.

    Absolutely love the composition.. great work! Except:
    * First one WB is a little off..
    * Eye's were screaming for some sort of texture... maybe offset with a lit candle flame

    Oh wait... this is a test.. Nevermind :) 

    DOF difference is as expected. Some discussions probably occurred when 135 negative started to overtake MF and LF in popularity decades ago.

    What has field of view got to do with it? The person doing the test has mixed a number of things - field of view, focal length, aperture and depth of field and concluded what exactly?

    Taking a FF and :43: camera to get the same picture (both field of view and depth of field) you need:

    • Half the focal length on the :43: sensor
    • Twice the aperture (half the f-number) on the :43: sensor

    So to get the same field of view/depth of field as a 50mm @ F2 on FF, you need 25mm @ F1 on the :43:. Clearly, this ignores lens rendering/bokeh issues, white balance and the fact the sensor aspect ratios are different.

    Oh yeah, I just noticed that the writer wrote "field of view." I suppose he meant DOF.
