I shoot an a850. If I attach a crop lenses, do I get FF DOF with it, or crop DOF? I am assuming if I shoot an 35 f1.8, I am getting the crop of 52mm 2.4 or whatever it is. Thanks.

You have to take in account the focal length, abgle of view, aperture and distance to the subject, and also the size of the final image. So DOF is more complex than just focal length and sensor size.
