>the point many have made about getting an FX camera to "regain the DOF" their FX lenses originally had. I >had always assumed that if I got the DX equivalent lens, the DOF would also be the same. Actually the Nikonians poll implied it is the few (under 10%) who want FF for less dof. One challenge of going for minimal dof is many lenses have a significant optical quality reduction especially on 24x36 at or near full aperture needed for minimal dof. Just about all sports, PJ and wildlife photographers want either extra dof or the option of a faster shutter speed with the same dof - the main reason many pros prefer cropped sensors to FF. The ideal is to take advantage of the unique features of each format by using both - something many Canon users have been able to do for years
Photography is a bit like archery. A technically better camera, lens or arrow may not hit the target as often as it could if the photographer or archer does not practice enough.
