Question for the group:
I understand that the effective focal length when using these lenses from 35mm to m4/3 is approx. 2x. When using the focus range numbers printed on the barrel, are these also doubled, or not since the lens is still focusing at the same distance away, and the sensor is just "cropped"? How about the DoF sizings (16, 8, 4, R, 4, 8, 16) that let me know how much leeway to either side I have? I understand the aperture doesn't change (measurement is based on size of lens vs opening created), but I have heard different answers on if the DoF changes for a given lens at the same aperture opening, depending on the sensor size (35mm vs m4/3).
Of course, all of these questions assume the lens barrel markings are accurate at their given distances when put on a 35mm body. Sorry if they have been asked before, couldn't see anything directly stating the above.
