Re: Micro 4/3rds vs. Full Frame

The myth persists that the size of the sensor changes the depth of field or the resolution.

The sensor only changes the size of the image you have to work with and the angle of view you get with a given focal length lens.

Lenses that are designed for small sensors can be made smaller and lighter because the image produced does not have to cover as large an area.

Lenses designed for large sensors have to be larger to get as much exposure on the sensor.  They have to produce a much larger image and make the exposure as even as possible.

The appearance that smaller sensors have greater depth of field is because the lens uses a shorter focal length to get the same angle of view that you would see with a larger sensor.
