     Hi LUGGERS
    =20
     I am curious about the coverage of the 28mm PC Super Angulon-R lens=2E=
=20
     According to the catalogue, this lens has an angle of view of 73/93=20
     degrees=2E I would assume the 93 deg is the coverage when the lens is=20
     shifted=2E
    =20
     Looking at the angle of view of the 19mm Elmarit-R, its coverage is 96=
=20
     degrees=2E Can I assume that, instead of using the 28mm PC with shift=20=
to=20
     maintain straight lines in my image, I use the 19mm and making sure=20
     that the film plane is parallel with the image, will also maintain=20
     straight lines in my image? When the final print is out, I just have=20
     to crop the unwanted foreground=2E
    =20
     I will then have the same coverage as the image taken with the 28mm=20
     PC=2E Is this really true? Would appreciate your comments=2E
    =20
     Thanks
