When you are ready for another ... consider the MANUAL focus Rokinon 85mm f/1.4, which, if you can live with manual focusing, will save you $1000 over its alternative, the SONY CZ 85mm f/1.4. This will give you a lens that makes the girls faces look just a little less pudgy (they like that). ![]() A solid pair of glass options. |

The thing about really tight apertures is the optical/physical phenomena of "diffraction." This effect of light scattering through an aperture causes the image to apparently soften, not sharpen, as the stream of incoming light waves are literally forced in different direction by interaction with the edge of the tightened orifice. It usually happens more dramatically past f/13 in most telephoto lenses. So going "tight" may give you a deeper depth of field, but your image begins to blur or softening to this effect. f/32 digital images are usually so badly affected by this phenomena that most of the images are effectively unusable. Just something to consider, if what you are getting is looking a little rough and you cannot figure out exactly why. Last edited by DonSchap; 12-09-2009 at 10:13 AM. |
