i have played around with a d70 + kit lens (which is i believe after googling is the AF-S Nikkor DX 18-70mm f3.5-4.5G IF-ED Zoom).
to achieve shallow depth of field with model sharp and background blur with the d70, i could only shoot half body shots (about waist up). when i tried full-length, i couldn't achieve the same depth of field... am i doing anything wrong? is it possible to shoot full-length + clear model + background blur with the kit lens? or will i have to get a lens with bigger aperture or longer lens?
i have pretty much decided on 400d + 17-85mm (but it only has maximum aperture of 4 though longer focal length..) would like to know what i'm in for (i.e. would i be able to take full-length shots with shallow depth of field or only half body?)
