Teleconverters (Multipliers) - A technical overview
Quote:
(1) They work no "magic" with depth of field. The depth of field of a 300/4 lens plus a 2x multiplier (= 600/8) is exactly the same as the depth of field of any other 600/8 lens. For a lens system of any given focal length and aperture, the depth of field is essentially the same, whether or not a multiplier is used.
