Focal Lengths with Teleconvertor lenses - Photography

Hi, Can anyone advise what the depth of field would be with a Sigma 70-200mm lens on a Nikon 801 fitted with a 2x teleconvertor. The lens would be working at the 200mm length. Many thanks. Ray -- This E-Mail has been checked by eTrust EZ Antivirus...

    Default Focal Lengths with Teleconvertor lenses

    Hi,

    Can anyone advise what the depth of field would be with a Sigma 70-200mm
    lens on a Nikon 801 fitted with a 2x teleconvertor. The lens would be
    working at the 200mm length.

    Many thanks.

    The DOF would depend upon the aperture you are using. I would imagine
    it might be as simple as halving what is printed on the barrel for a
    given aperture.
