Tilt Shift lens How effective is a tilt shift lens in getting that sharp "front to back" look you see in large format photos? Are they just as effective with a digital camera as with a film camera. i.e any comments on the 85mm Nikon tilt shift lens for landscape/nature photography. I love that perfect depth of field look of a 4x 5, but do not want to make that big of a switch!!! :) Joan

Joan, the 85PC lens is designed for use as a macro lens - and for that it's great with film, slightly less so with digital. This is because while the 85MM focal length translates into about 130MM effective focal length (crop factor) which is nice enough for macro work, the perspective control adjustments are somewhat less noticeable. The larger the image area, the shallower depth of field is at a given f-stop. So with a 4x5 camera DOF is pretty shallow, even at f11 or thereabouts, so tilting to get all the ground, say, into the focal plane really becomes apparent. But with the relatively tiny format of a DSLR, DOF is already much greater at that samne f11 aperture - so the difference in tilting is somewhat attenuated. When I shoot flowers (using tripod, angle finder, etc.) I can see some slight differences when I tilt the lens - but it's not nearly as obvious as with my 4x5. For macro work, though, the shift feature is quite nice - it's like a very-fine-tune control for lateral lens positioning/image composition.

Thanks Bob, that helps clarify my question. Thanks for taking the time to explain it to me! Joan
